After conducting several dives with the Canon 7D inside the Aquatica A7D housing, I can confidently say that the combination delivers an outstanding underwater shooting experience. Coming from an older Canon 40D/50D setup with a matching Aquatica housing, the most immediate improvements were in the viewfinder and autofocus performance.
The 7D’s viewfinder, enhanced by the optional AquaView accessory, is noticeably brighter and more expansive. Autofocus speed underwater is another major highlight—it’s remarkably fast and responsive, bringing a significant improvement over my previous setup. The internal fit and finish of the housing are precise, ensuring a snug and secure placement for the camera body. However, one minor drawback was the lack of a factory-installed moisture alarm. Installing it manually was not difficult, but pre-installation would have been appreciated.
Features of the Aquatica A7D Housing
The Aquatica A7D housing showcases a high level of engineering precision. Machined from a solid block of aluminum, it provides both strength and durability for deep diving applications. It is rated for depths of up to 90 meters, with an optional upgrade to reach 130 meters, ideal for deep wreck and cave exploration.
Connectivity options include both optical and sync cord bulkheads, giving flexibility to various lighting systems. The housing features a bayonet port mount, allowing for quick and secure lens and port changes without removing the camera body from the housing. This design offers versatility underwater, especially when changing from macro to wide-angle configurations. Optional accessories like a hydrophone and a high-quality AquaView viewfinder enhance the shooting experience further.
Underwater Still Photography Experience
Compared to its predecessors, the Aquatica A7D housing is more compact and lightweight. When paired with my existing collection of lenses, strobes, and ports, transitioning to the 7D was seamless for still photography. The controls—aperture, shutter speed, and shutter release—are logically positioned and easy to operate, even underwater.
The design improvements include dials with more pronounced edges, making them easier to grip while wearing gloves in colder waters. The buttons respond well despite being spring-loaded, and the angled button bank on the rear left is ergonomically placed for quick access. One notable feature is the handgrip design, which offers a very comfortable hold—tailored for practical underwater use.
Display and LCD Visibility
The LCD visibility on the Aquatica A7D housing is excellent. One issue I encountered with the 50D was partial screen obstruction, particularly with the AquaView viewfinder. The 7D housing resolves this by optimizing the position of the rear LCD window, making the display fully visible even with the AquaView attached. Although some divers might miss the traditional top LCD screen, I personally never relied on it with previous Canon models, especially considering that the main information display is accessible through the 7D’s built-in screen.
Buoyancy and Balance Underwater
While I did not collect exact measurements for buoyancy, I can share general observations. With an 8” dome, a 28mm lens, two DS-125 strobes, and 6” Stix arms combined with 10-ounce floats, the entire rig is just slightly negatively buoyant. However, the setup tends to rotate upwards due to the buoyant dome. Using a flat port increases the overall negative buoyancy and minimizes the rotation, creating a more stable configuration.
The housing does not feel heavy in water. It maintains neutral handling characteristics, especially with the aid of floatation accessories. This makes long dives and complex shots much easier to manage.
Introduction to Underwater Video with the Canon 7D
Diving into the realm of underwater video using the Canon 7D was a new experience for me. While I had a solid background in still photography, I approached video with only a beginner’s understanding. The Canon 7D offered exciting video capabilities that I was eager to explore, and the Aquatica A7D housing promised a durable, ergonomic interface to support that journey. Though my initial expectations were modest, the potential became increasingly apparent as I learned to manage focus, exposure, and stability in an underwater environment.
Using video underwater presents a unique set of challenges that differ significantly from shooting stills. These include maintaining consistent focus, dealing with ambient light shifts, stabilizing the camera, and composing shots on a moving platform. Despite these hurdles, I was eager to make the most of the Canon 7D’s strengths—particularly its fast autofocus system, strong high-ISO performance, and full HD video recording capabilities.
Challenges with Underwater Macro Video
I initially attempted underwater macro videography using the Canon 60mm macro lens. It quickly became clear that this was not a beginner-friendly task. Macro shooting demands an extraordinary level of precision in focus and camera stability—both of which are difficult to achieve underwater, especially without support equipment. The small movements caused by currents, breathing, and even hand tremors make it nearly impossible to maintain sharp focus on small subjects. After multiple failed attempts at recording usable footage, I realized that a tripod or some form of underwater stabilizer is almost mandatory for serious macro video work.
One of the primary issues I encountered during this phase was focus inconsistency. The Canon 7D offers different methods of autofocus during video recording, but macro videography demands pinpoint control, and the slightest deviation from the subject's focal plane results in unusable footage. In my early attempts, I made the mistake of remapping the AF-ON button using custom controls designed for still shooting. While this configuration was excellent for photos, it effectively disabled autofocus while recording video. As a result, I had to rely entirely on manual focus, which proved incredibly difficult in macro scenarios.
After realizing the limitations of my setup, I decided to create a dedicated video shooting mode using the C1 custom mode on the camera. This allowed me to switch quickly between a still-focused Manual mode and a video-specific configuration that preserved autofocus functionality during recording. This separation made a big difference in usability and allowed for more fluid transitions between different shooting tasks during a single dive.
Wide-Angle Video Potential and Real-World Performance
After struggling with macro, I shifted my focus to wide-angle video, where the challenges are different but more manageable for someone with my experience level. I used a Canon 28mm f/1.8 lens, which provided a broader field of view and a greater depth of field. These characteristics made focus maintenance much more forgiving. Stability also became less critical, as wide-angle footage tends to show less motion distortion from minor movements. The resulting clips, while not yet professional grade, were significantly more usable and visually pleasing than my earlier macro attempts.
Wide-angle video is particularly well suited to wreck and cave diving, where large structures and ambient light play key roles in composition. One of my concerns going into these environments was the low-light performance of the camera. Fortunately, the Canon 7D performs admirably at ISO 800, maintaining image quality with minimal noise. While I lack a direct comparison to other systems, the output is crisp and well-exposed given the circumstances.
Locking focus before recording is one effective technique I adopted when shooting wide-angle. By using the shutter button or AF-ON to acquire focus, then switching to manual mode or disabling autofocus temporarily, I could avoid focus hunting during recording. This method works well as long as the subject remains in a consistent focal range. The camera’s depth of field, especially at f/5.6 or narrower, provides enough buffer to keep moving subjects reasonably sharp.
Aquatica Housing Ergonomics for Video Use
One issue that surfaced during my video tests was the placement of the Start/Stop button on the Aquatica housing. To activate video recording, you must press this button, which is located in such a way that it is nearly impossible to reach while keeping your right hand fully on the grip. With my large hands, I still had to disengage from the grip to operate the button, which made smooth shooting transitions difficult. In still photography, this is not a problem, but for video, where you want to start recording without altering your framing or focus, this design becomes a hindrance.
The problem is most pronounced in macro video or scenarios that require careful framing. When I released the grip to press Start/Stop, I often shifted the camera’s position, lost focus, or even bumped into the subject. For wide-angle video, this was less of a problem because I had more room to reposition the shot after pressing the button, but it’s still not ideal. In future versions of the housing, a repositioned or remote Start/Stop control would be a welcome upgrade.
I experimented with a workaround using AF Live mode during video to reacquire focus. Unfortunately, underwater AF Live is unreliable and often results in jittery footage with rapid exposure shifts. It also introduces significant lag and hunting, which ruins the continuity of the video. In practical terms, I ruled out AF Live as a viable option for underwater use.
Exposure Settings and Low-Light Considerations
Shooting video underwater requires careful control of exposure. The need to balance ISO, aperture, and shutter speed becomes more critical when working in low-light conditions, such as deep wreck dives or during overcast weather. I typically aim for ISO settings around 640–800, depending on the ambient light and the reach of my artificial lighting setup. The Canon 7D handles these ISO ranges with grace, producing relatively noise-free footage with decent dynamic range.
One of the trade-offs I encountered was between aperture and lighting power. My strobe light, the Fisheye HG20DX, does not provide enough illumination to support small apertures like f/16, so I often shoot more open at f/2.8 to f/5.6. This creates a shallower depth of field, which can be artistic but also unforgiving when it comes to maintaining focus. Choosing the right aperture is a balancing act between desired focus depth, image sharpness, and lighting conditions.
Video demands consistent lighting, and while my Fisheye light worked adequately, I frequently encountered situations where the frame lacked even illumination. Shadows became a challenge in uneven terrain or when following moving subjects. A more powerful video light or a second light source would be ideal to evenly light the scene. The quality of footage improves drastically with well-distributed lighting, particularly when trying to capture rich colors and fine details in wide-angle scenes.
Audio Considerations in Underwater Video
The Canon 7D features a built-in microphone, and while it’s serviceable, its utility underwater is limited. I opted not to install the optional hydrophone accessory offered by Aquatica, reasoning that most compelling underwater video is ultimately overlaid with music or narration in post-production. That said, the built-in mic captures environmental sounds reasonably well. You can hear breathing noises, regulator bubbles, and even ambient hums if you’re close enough to mechanical structures.
While not essential for casual shooters, audio can add an immersive layer to underwater footage. In specific cases, such as documenting marine life behavior or diver interactions, retaining natural sound might be valuable. However, given the limitations of built-in microphones underwater, serious videographers will want to invest in hydrophones or external audio recording devices.
Stability and Movement Underwater
One of the most important lessons I learned was how critical camera stability is during underwater video recording. The weight and balance of the rig play a major role in determining how steady your footage will be. My setup, which included floatation arms and lightweight strobes, provided reasonably balanced handling, but it was still prone to small drifts and bobbing movements. Using two hands, proper trim, and slow breathing techniques helped, but I still experienced occasional wobbles.
Macro subjects in particular highlight any camera movement. The slightest motion can shift your frame and throw focus off completely. This is why a tripod or stabilizer is essential for high-quality macro video. For wide-angle scenes, the movements are less noticeable, but smooth panning and hovering techniques still require practice.
To improve stability, I began to pay more attention to my buoyancy control and breathing rhythm. Holding breath temporarily before initiating a shot, maintaining eye-level posture, and using both hands in a braced grip all helped to minimize shake. Over time, I noticed a significant improvement in the quality and watchability of my clips.
The Role of Custom Functions and Video Modes
One of the most useful aspects of the Canon 7D is its customizable control system. By assigning video-specific settings to the C1 or C2 mode, I created a seamless workflow that separated my video setup from still photography. This allowed me to quickly switch between two shooting styles with a single dial rotation, avoiding lengthy menu dives during a dive session.
In my video mode, I preset the camera to aperture priority, set the aperture around f/4 or f/5.6, ISO at 640, and enabled autofocus. This configuration struck a balance between sharpness, low-light performance, and ease of use. I also turned off image review to save battery and memory card space, as repeated clip reviews can be time-consuming underwater.
Custom functions allowed me to disable unnecessary features and reassign controls, helping me adapt the camera to the specific challenges of underwater video. This is one of the camera’s greatest strengths—it empowers users to tailor the experience to their needs.
Lighting Gear and Future Upgrades
My current lighting setup, while functional, left me wanting more power and flexibility. The Fisheye HG20DX provides continuous lighting but lacks the output to support complex scenes or expansive wide-angle subjects. To improve, I plan to upgrade to a dual-light system with adjustable beam angles and stronger intensity.
For those looking to shoot professional-grade underwater video, investing in high-powered LED lights with diffusers is essential. These lights not only provide better exposure but also help restore color, which is often lost at depth. Red filters, manual white balance, and post-production color grading can also assist in enhancing the visual appeal of underwater footage.
Above-Water Handling of the Aquatica A7D Housing
The Aquatica A7D housing proves to be just as reliable above water as it is beneath the surface. Handling it on land offers the first sense of the engineering quality that Aquatica has delivered. The housing feels rugged, precise, and secure in hand. While slightly heavy, as expected from a solid aluminum build, it balances well when fitted with a dome port and strobes. The grip handles are sturdy and comfortable, molded perfectly for firm control. Whether you're assembling the system on a dive boat or prepping gear at home, the ergonomic contours of the housing make the setup process straightforward.
On deck or in transit, the housing’s robust construction provides peace of mind. The finish is a deep black coating that not only looks sleek but also appears highly durable. It resists scratches and holds up well to exposure from sea spray, sand, and minor impacts. Even when loaded with a camera, strobe arms, dome port, and floatation accessories, the housing feels cohesive and manageable.
Aquatica’s attention to detail is especially noticeable during practical handling. All levers, buttons, and dials are logically placed. Nothing feels loose or poorly aligned. The buttons are spring-loaded yet remain tactile, even with gloves on. The locking mechanisms are responsive and firm, making accidental disengagement unlikely.
Camera Mounting and Interior Access
Installing the Canon 7D into the Aquatica housing is simple and smooth. The camera slides into place with precision, sitting perfectly within the internal mounts. Everything aligns without force, and the ports match their controls accurately. Aquatica has worked hard to ensure that there is no ambiguity when placing the camera inside. You immediately sense that the design is tailored for an exact fit.
One limitation is that once the camera is inside the housing, you cannot remove the memory card without taking it out again. This is not a dealbreaker, but it does make pre-dive preparation crucial. You need to double-check your card capacity before sealing the housing. Fortunately, battery replacement is more forgiving and can be done without completely disassembling the system.
Removing the camera is equally easy. Even when a lens and zoom gear are attached, the housing allows for a straightforward withdrawal. You don’t need to remove the dome port unless you’re changing lenses, which saves valuable time during quick turnarounds. These small design choices enhance the experience and prevent unnecessary fiddling.
Port System and Locking Mechanism
The port mount system on the A7D housing uses a bayonet configuration, allowing quick changes between dome ports and flat ports. It’s a robust and intuitive system. Ports lock firmly into place, minimizing the risk of leaks or disconnection during a dive. One limitation of this system is that it only locks the first port component to the housing. If you’re using additional accessories, like a collar or extension ring, the lock doesn’t secure those in place directly.
This doesn't create a major risk if everything is assembled correctly, but it’s a small design element that could be improved. For multi-part setups, it’s essential to double-check the bayonet alignment to ensure every component is seated tightly before entering the water.
Maintenance and Saltwater Cleaning
After multiple dives, one of the pleasant surprises has been the ease of post-dive cleaning. Salt buildup, a common nuisance with other housings, has been noticeably minimal. The button design appears to include recessed holes that let fresh water flow through, washing out salt more efficiently. This subtle yet impactful design choice helps extend the life of the housing and makes routine maintenance more effective.
Soaking the housing in fresh water after each dive is still essential, but the internal components and buttons do not show the same salt crust that I experienced on my older Aquatica model. The smoother o-ring grooves and seals make it easier to apply lubrication and check for debris. The main bulkhead o-ring, in particular, now sits more evenly and doesn’t shift around in the groove like older versions. This refinement is reassuring, as it reduces the risk of flooding due to misalignment.
The rear port o-ring and buttons have similarly been improved. O-rings on my previous housing often became dislodged or pinched during installation. The newer design includes a machined edge at the housing hole, allowing o-rings to slide in more naturally, especially when inserting the AquaView viewfinder. Installation is smoother and feels more secure overall.
Build Quality and Exterior Design
The Aquatica A7D housing is machined from a solid aluminum block, then anodized and powder-coated for corrosion resistance. This material choice ensures strength under pressure while keeping the housing compact and streamlined. Aquatica intends for this housing to withstand harsh underwater environments over many years.
The matte black exterior is more than just cosmetic. It helps reduce unwanted reflections underwater, making it easier to frame shots without light bouncing off the housing. The paint holds up well against scratches and doesn’t chip easily. After multiple dives and handling in abrasive environments, the housing still looks close to new.
The buttons, dials, and levers also demonstrate durability. Each component is engineered to operate reliably even after repeated use. I’ve experienced no sticking or stiffness in the controls, even after multiple dives in saltwater. The design doesn’t compromise functionality for aesthetics—every detail appears to have a purpose.
Strobe Compatibility and Connection Options
Strobe lighting is essential for any serious underwater photographer or videographer, and Aquatica provides excellent flexibility in this area. The housing supports multiple bulkhead options, including Nikonos, Ikelite, and optical fiber connections. This allows compatibility with a wide range of strobe brands like Inon, Sea & Sea, and Ikelite.
My current configuration uses one Ikelite bulkhead and one optical fiber connection. This dual setup gives me versatility. I shoot primarily with DS-125 strobes via a Y-splitter cable, which has been effective for consistent lighting. However, I’ve also purchased a pair of Inon Z240s for situations requiring lighter and more compact strobes. The ability to switch between these options without modifying the housing is a clear advantage.
In addition to hardware flexibility, the strobe configuration also supports TTL and manual camera-based control. While I primarily shoot in manual mode, having the option for TTL is useful when working in unpredictable lighting conditions or when shooting fast-moving subjects.
Underwater Ergonomics with Strobes and Arms
When paired with strobe arms and floatation devices like Stix arms, the housing balances well in the water. It does not feel excessively front-heavy or cumbersome. This is important during long dives, as gear fatigue can quickly build up when handling poorly balanced rigs. My setup, which includes 6” Stix arms and 10-ounce floats, creates a nearly neutral buoyancy profile. The dome port causes some upward rotation, but this is manageable with proper hand positioning.
The handles on the housing are molded with comfort in mind. Even during dives exceeding an hour, they remain comfortable to grip. Controls are accessible from both the left and right handles, allowing quick changes to exposure settings without having to let go of the rig. The dial positions are intuitive, and their textured surfaces make them easy to rotate even while wearing gloves.
Shooting with strobes also highlights the housing’s attention to detail. The strobe connectors are placed to avoid tangling, and cables are routed cleanly. You won’t find yourself struggling with obstructed controls due to bulky sync cords. It’s this kind of foresight that makes Aquatica a favorite among serious divers.
Durability in Harsh Conditions
Diving environments vary greatly, and equipment must be able to perform reliably in all of them. Whether exposed to the salt-heavy currents of ocean wrecks or the fine sediment of freshwater caves, the Aquatica housing has held up impressively. There have been no signs of corrosion, stiffness, or mechanical wear, even after frequent use.
The deep-rated springs make the housing ideal for technical diving. Many housings top out at 60 meters, but the Aquatica A7D supports dives up to 130 meters with upgraded springs. This gives photographers and videographers the confidence to explore deeper wrecks and cave systems without fearing mechanical failure. For those interested in technical diving and trimix or rebreather dives, this depth rating is critical.
Every component feels over-engineered for strength. Hinges, latches, and even the viewfinder port demonstrate superior craftsmanship. This translates into a piece of gear you can trust when equipment failure is simply not an option.
Advanced Techniques for Managing Ambient Light and White Balance
Ambient light, while often beautiful, can be unpredictable and inconsistent. To manage it effectively, photographers frequently use light modifiers, including:
-
Reflectors: Bounce ambient light back onto the subject to fill shadows naturally.
-
Diffusers: Soften harsh ambient sunlight, reducing contrast and creating even tones.
-
Flags and Gobos: Block or subtract unwanted light from parts of the composition, allowing selective lighting.
-
Gels: Colored gels placed on lights or reflectors can alter the ambient light’s color temperature, especially when mixing artificial and natural light.
Using these tools can help maintain consistency in exposure and color across a shoot, even when ambient light conditions fluctuate.
Blending Ambient and Artificial Light
In many professional setups, photographers must balance ambient light with artificial sources such as strobes or LED panels. Achieving a harmonious blend requires:
-
Matching Color Temperature: Use lights with adjustable white balance or attach gels to match the ambient light.
-
Metering Both Sources Separately: Use a light meter to evaluate the strength of ambient light and the artificial source independently.
-
Controlling Light Ratios: Adjust the artificial light output to complement or overpower the ambient light depending on the desired effect.
This technique is often seen in wedding photography, environmental portraits, and architectural shoots where ambient ambiance must be preserved while ensuring subject clarity.
High Dynamic Range (HDR) and White Balance
HDR photography captures multiple exposures and blends them to create a balanced image that retains detail in shadows and highlights. When using HDR:
-
White Balance Consistency is Crucial: All bracketed exposures should maintain the same white balance setting to ensure color uniformity during blending.
-
Manual White Balance Preferred: Avoid auto white balance for HDR series, as small shifts between frames can create color inconsistency.
Photographers often shoot in RAW to better handle dynamic range and white balance corrections during post-processing.
Shooting in Mixed Lighting Conditions
Mixed lighting involves ambient light sources of different color temperatures—like daylight through a window and incandescent indoor lighting. Strategies to handle this include:
-
Identify Dominant Light Source: Determine which light source defines the subject and set the white balance accordingly.
-
Use White Balance Presets Strategically: Choose between daylight, tungsten, fluorescent, etc., depending on which light dominates.
-
Balance with Gels: Use CTO (Color Temperature Orange) or CTB (Color Temperature Blue) gels to adjust artificial lighting to the ambient color temperature.
Mixed lighting scenarios require keen observation and technical control to avoid unnatural hues and maintain visual harmony.
Post-Processing Techniques for White Balance Correction
RAW Format and White Balance Flexibility
Shooting in RAW rather than JPEG offers significant advantages:
-
Non-Destructive Editing: RAW files retain all sensor data, allowing white balance to be adjusted freely in post without quality loss.
-
More Accurate Color Grading: Allows precise control over temperature (blue to yellow) and tint (green to magenta) sliders in editing software.
-
Greater Range for Creative Decisions: You can reinterpret the mood of a photo by adjusting warmth or coolness to suit storytelling purposes.
Software like Adobe Lightroom, Capture One, and Adobe Camera Raw provides robust tools for refining white balance after capture.
Using Neutral Reference Points
In post-processing, a neutral reference point—such as a white or gray object in the scene—can help recalibrate color balance. Tools include:
-
White Balance Selector Tool (Eyedropper): Clicking on a neutral tone in the photo allows the software to adjust the image’s color temperature.
-
Custom Profiles and Presets: Frequently used in batch editing to apply a consistent white balance across a series of images.
For the best results, a gray card or X-Rite ColorChecker placed in the first shot of a session can be used later to calibrate all images in the same lighting environment.
Advanced Color Grading Techniques
After setting a neutral white balance, photographers may creatively grade images to enhance emotion or match a style. These techniques include:
-
Split Toning: Adds distinct color tints to shadows and highlights for a cinematic effect.
-
HSL (Hue, Saturation, Luminance) Adjustments: Fine-tunes individual colors without affecting the rest of the image.
-
Color Calibration Panels: Adjusts primary RGB color channels to shift mood or correct sensor-specific tints.
White balance serves as the foundation for these advanced edits, ensuring a clean starting point for creativity.
Troubleshooting Common White Balance Issues
Unwanted color casts can result from:
-
Incorrect White Balance Presets: Choosing the wrong setting (e.g., tungsten under daylight) shifts the entire image.
-
Reflections and Bounce Light: Colored surfaces reflecting light onto your subject (like grass causing green skin tones).
-
Low-Light Auto White Balance Errors: In challenging light, AWB can misinterpret the scene and skew color temperature.
Solution:
-
Identify the source of the color cast.
-
Adjust in-camera settings or use the white balance eyedropper tool in editing software.
-
Consider black-and-white conversion if color correction is impossible but image composition remains strong.
Issues with Skin Tones
Skin tones are sensitive to white balance errors, particularly under mixed or fluorescent light. If skin appears too red, yellow, or green:
-
Use a Kelvin value between 4800–5500K as a starting point for natural skin tone.
-
Manually correct tint and temperature sliders until skin appears lifelike.
-
Avoid over-saturation in post-processing, which can exaggerate errors.
Skin tones are often the benchmark for evaluating white balance accuracy, especially in portrait and fashion photography.
Fixing White Balance in Video
Unlike stills, video footage requires more planning since white balance is baked into the file. To fix or avoid problems:
-
Manual White Balance Before Shooting: Essential for consistent footage across scenes.
-
Use Color Correction Panels in Editing Software: Tools like Lumetri Color (Adobe Premiere Pro) or DaVinci Resolve allow fine-tuning.
-
Match Cameras with Custom Profiles: When using multiple cameras, align color profiles to maintain consistency.
White balance errors in video are more complex to correct, so proper setup is critical.
Conclusion
Mastering ambient light and white balance is not just a technical requirement—it is an artistic skill that enhances every photograph or video you produce. Ambient light gives your scenes authenticity, mood, and depth, while white balance ensures the colors remain true to life or fulfill a creative vision.
Understanding how to measure and manipulate color temperature, whether through camera settings, physical tools like gels and reflectors, or digital post-processing, provides complete control over your image’s tone and atmosphere. Moreover, learning to troubleshoot challenges like mixed lighting, color casts, or variable daylight ensures reliability in diverse shooting environments.
Ultimately, the best photographers and videographers are those who observe how light behaves, how colors interact, and how they can make those elements work together. Whether you’re capturing a sun-drenched landscape, a candlelit dinner scene, or a corporate headshot in a fluorescent-lit office, your command over ambient light and white balance determines the story your image tells.
With practice, technical insight, and creative awareness, you’ll develop the instinct to read light and correct color effortlessly—turning ordinary frames into impactful visual narratives.
