As my skill improves, I have been experimenting with underwater technique. At this point I am using natural light and custom white balance. And I have been off wide angle and gone to zooming in more. Does it matter? Well to me it’s an acquired skill and will hopefully get me more dramatic images. Hey, who really cares how hard it was? The ‘net is full of good stuff. But to me it’s all part of a new skill set and education.
