Use a combination of a color correcting filter plus white balance adjustment.

There are several options to improve the color of our images. What Can We Do to Get Colors Back in Our Underwater Images?

Granted, it is a lot easier to talk and write about filters by using the term 'depth,' which we will do here. It is distance that affects color, not depth! Because of this effect of physics, it is not possible to have any type of filter or camera white balance that can simultaneously compensate perfectly for both near subjects ('this end' of the wreck) and distant subjects (the 'far end' of the wreck). When you hover 100 feet above the wreck, looking straight down, both ends of the wreck will look the same. When you think of water's effect on color as being caused by distance, not depth, you can understand why, when at depth, the 'far end' of the wreck will look different than the 'close end' of the wreck. The main point here is to always think of water's effect on color as an effect of distance, rather than just an effect of depth. That's Roy G Biv and you can not change physics. Regardless of what depth you and that coral are at, the farther away you are, the more the color is changed. If you set your camera exposure perfectly for the coral in each case, you will see the colors of the coral looks identical in both images (the background water will of course look much different). Yes, at 90 feet deep, the coral will be much darker than at 10 feet. The colors will be identical in both of these situations. Now think about this situation how would the colors of that coral look if it were 90 feet deep and you were 90 feet deep and 10 feet away? What if the coral were 10 feet deep and you were 10 feet deep but 90 feet away? Roy G Biv explains why a coral at 90 feet deep will have much less red, orange, yellow, than the same coral 10 feet deep. This is why deep water looks deep blue and shallow water looks clear. The farther the light travels the more the color of the light is changed. Not only will it help us see better, it will help us see the beautiful colors of all that underwater life. Us divers know that the deeper we go, the darker it is. blue! It's about distance, not depth!ĭuring our open water scuba diving course, most of us are taught that 'the deeper you go, the more color is lost.' That is true, but it is not complete. If the pool was painted white and then filled with water, the homeowner, expecting the pool to look white, would be very upset to see that his just-filled-up-today-with-clean-water-pool appears. Have you ever noticed that swimming pools are always painted blue? They are painted blue so that the homeowner will expect the pool to look blue. All water absorbs light according to the rules of Roy G. No matter how clean your water is, if you have enough of it, it will appear blue. Your glass of water just is not big enough to have enough effect that you can readily see it. After travelling 10 meter through 'coastal ocean water' the blue light will now be relatively 58 times more intense than red light! But, I Just Poured a Glass of Water and it is Perfectly Clear It's Not Blue! Blue light will have 35% of its intensity remaining, but red light will only have 0.6% of its intensity remaining. Studying the charts further, let's look at the relative strengths of light after travelling 10 meter (33 feet) through the same pure ocean water. The blue light, relative to red light, is approximately 1+1/2 times 'too strong.' You should be easily able to adjust for that differene in the camera with 'white balance' adjustment. It is fairly well documented that after travelling through 1 meter (3 feet) of 'coastal ocean water,' blue light will still have 90% of its intensity, but red light will have only 60% of its intensity. We will explain the relative effects of color change of light travelling through water based upon an article published by Texas A&M's Department of Oceanography.

Next is orange orange is not affected as much as red, but it is affected more than all of the other colors.

At the beginning of that list is red, and red is affected more than any other color through water. It is also the order that they fade as we look through water. It's not just the colors we underwater photographers want to remember, it is the order in which they make up Mr. Biv is an acronym for Red Orange Yellow Green Blue Indigo Violet - the colors of the rainbow. Though Roy is not a real person, you may want to learn and remember how he was given his name.
