Light & Color – Testing the Keldan Ambient Filter Concept
One big thing that moves us is getting the color right. Or maybe even before that … how do things actually look like under water? Is it fine to show everything the same way we would see it with our own eyes? Or do we want to bring out the color that is hidden down there? To answer these questions one will sooner or later come to realize that it is not an easy task to bring out the natural color under water. Even just to explain the difficulties is complex.
Lets start with the correct Â white balance. We need to tell a digital camera what ‘white’ is in order to enable the camera to adjust the colors correctly. Over water there are a bunch of settings like ‘Auto White Balance’, ‘Daylight’,’Cloudy’ and so forth. But there settings doesn’t work under water, because the water filters out the actual color. And if that wouldn’t be pain enough water even doesn’t filter out all colors at the same rate. Red is the first color you will loose. In order to get the colors right we have to da a manual white balance whenever we change depth. But don’t expect too much from that. This will not bring back the colors that you lost to the amount of water above your head.
What about video-lights? They are supposed to bring back the natural color right? Well, yes and no. Since the lights will most certainly not have the same color temperature like the ambient light, you will have to decide where you will calibrate your cameras white balance on.Â If you do it on the ambient light, the video-light will look very reddish. If you do it on the video-light, the background will have the wrong color. It all comes down the the conclusion that you will have to do whatever you think looks best in the final picture. Really? Well, there is a very interesting new concept that is a gamne-changer â€¦ at least in our eyes. Check out the Video above to find out more about it.
