What is the learning curve for underwater video?
The learning curve for underwater video is typically shorter than that when learning underwater still photography. A video camera’s auto-focus, auto-shutter speed, and auto-exposure features can be used to relieve the burden of having to manually fiddle with these settings between each shot. Using these automatic controls, you can concentrate more on shooting than figuring out exposures and still get decent results. Video cameras also work well in low-light, so you may be able to get by without lights until you gain experience with the fundamentals of shooting video underwater.
