nderwaterphotography lends itself to computer manipulation of images as the potential to ‘improve' the image is so great. Eliminate backscatter, move that fish a bit to the right, delete the other diver's fins behind the main subject, add another shark or two... Is it legitimate photography? Of course it is. Image manipulation may contravene the rules of a photographic competition, but for commercial or personal use, the end result is what counts, irrespective of how it was ‘captured'. This book is excellent, the first of its kind that I know of, to address the specific problems of underwater images. And the knowldge gained is of course applicable to all images. Chapters include, the digital process, scanning images, resolution, photo software, image adjustments, photographic curves, backscatter, grain reduction etc etc - and ‘The Ethics of Photo Manipulation'. The book considers the use of Adobe Photoshop in its examples, but any photo software is applicable.
