Water changes colour quickly. Red disappears first, then orange, and soon everything looks blue or green. When you edit underwater photos in Photomator, the challenge is to restore a sense of the real scene without making the water look like a swimming pool or the reef look painted.
Underwater editing starts with accepting limits. A deep photo without artificial light will never have the same colour range as a surface photo. Your job is to recover what is there, keep water believable, and protect the subject that matters most, whether that is a diver, a turtle or a coral detail.
Fix the colour cast first
White balance is the most important underwater correction. Shift the balance away from blue or green until skin, sand or a known colour looks closer to reality. Use a reference in the frame if one exists, such as a white fin, a grey rock or a dive slate. If no reference exists, judge by skin and sand rather than by the water alone.
After white balance, use selective colour or colour balance controls to refine the remaining cast. Deep water often needs a different correction in shadows than in highlights. Work gently and check the result on a larger screen. A correction that looks right on a phone can look too warm or too magenta when viewed larger.
Restore depth without oversaturation
It is tempting to push saturation to bring back reef colour. A small increase can help, but a large one makes coral look neon and water look artificial. Instead, correct white balance first, then add saturation in small steps. Check each colour separately. Reds and oranges are usually the colours that need the most help, while blues and greens are already strong.
Use local adjustments for the subject. Brighten a diver or a fish slightly, or add a touch of contrast to a coral head, while leaving the surrounding water alone. That separation keeps the subject clear without turning the whole frame into a saturated backdrop. For colour work in general, see the guide to colour grading photos in Photomator. For low light and noise, the guide to editing night photos in Photomator offers useful checks.
Light, contrast and particles
Underwater light falls off with distance. A subject close to the camera may be bright while the background fades into blue. Use highlight and shadow controls to balance that falloff, but do not try to make distant water as bright as the foreground. Depth is part of the scene, and a natural gradient from subject to background feels more honest.
Particles, known as backscatter, are common in underwater photos. Small bright spots can distract from the subject. Remove the most obvious ones only if the result still looks natural. Do not smooth the whole image to hide particles, because that also removes texture from coral, sand and skin.
A practical underwater workflow
Work in this order. Correct white balance, set exposure, recover highlights and shadows gently, refine colour in small steps, then make selective adjustments to the subject. Finally, check the water. If it looks grey, brown or unnaturally blue, revisit white balance rather than adding more saturation. A final before and after comparison is especially useful underwater, because colour memory can drift quickly while editing.
Frequently asked questions
Why are my underwater photos all blue?
Water absorbs red light first, so deeper photos lose warm colours. White balance correction can restore some warmth, but very deep photos without artificial light will always have a limited colour range.
Should I use a red filter or fix colour in editing?
A filter can help at capture, especially in shallower water, but editing gives more control afterwards. Use whichever approach gives a natural result for your depth and light, and avoid stacking both to an extreme.
How do I edit underwater skin tones?
Correct the overall cast first, then make a small selective adjustment to skin if needed. Skin should look warm and alive, not grey or magenta. Check both faces in a group photo, since light can fall unevenly underwater.
Can Photomator remove backscatter?
It can help with small, local cleanups, but heavy backscatter is best reduced at capture with better light positioning. Editing should remove distractions, not rebuild a scene that was obscured.
Is it better to shoot underwater in RAW?
Yes, when your camera or housing supports it. RAW gives much more room for white balance correction, which is the most important underwater adjustment. JPEG leaves less room to recover colour after a strong cast.
Keep water honest
Good underwater editing does not pretend the photo was taken on land. It restores the colours that were really there, keeps water recognisable as water, and lets the subject stand out without looking artificial. Correct the cast, work in small steps, and stop when the scene feels like the dive you remember.
