I digress for a few days. I haven’t dived since Ramadan. It’s experiment day. White balance is a nightmare underwater. My dive instructor took some nice shots and was using the same equipment without flash. He white balanced from a white clipboard. The shots were pretty good. I’ve used flash but a lot of shots were overexposed. Underwater setting produced too much blue green tint. The problem is hard because the color changes as you go deeper. It kind of takes away the spontaneity of the moment. And with fish it’s a 3D world with camera, photographer, and fish in motion at the same time. I used custom white balance and utilized the white underwater flash card on the camera. The main problem is the shutter speed tends to be too slow to stop motion. There are lots of other variables. The lionfish wasn’t moving so that helped here in this image. The color is not quite what I had hoped for. And the original image was upside down because that’s how the fish hoovers. It’s not bad but could use some punch in the color. Flash might have helped. We were moving along too quickly to take more than one or two images.
