I've added a new entry to my blog that provides a step-by-step 'how to' workshop for electronic (Photoshop) editing of underwater photos.
Whilst the techniques are valid for photographers at all levels, the use of color correction and backscatter removal will pay especial dividends for novice photographers with point-and-shoot cameras. With no external strobes, point-and-shoot cameras often provide photographs that appear to be 'washed out' and lacking in red pixels. Any use of the internal flash is likely to lead to significant 'backscatter' (reflections from suspended particles).
My article details a simple 10-step process that can provide nice results.
