Im playing with post photograph processing with paint shop pro 9 and photoshop but running against a brick wall. The PSP "one step photo fix" seems to help some photos an awful lot however the blue water takes on a sometimes blocky appearance after some of the processing. Trying similar enhancements in photoshop produces similar results. Is this an unavoidable consequence of image processing or are there techniques im missing to avoid this ? http://string.whitcombe.org.uk/files/turtle-original.jpg is the original image. Notice the washed out green appearance i want to get rid of. http://string.whitcombe.org.uk/files/turtle-1step.jpg is the PSP one step click alteration, note the blockiness the water at the top takes on. I got a similar result with photoshop. It *appears* to be the auto contrast adjust causing this but contrast needs to be altered to bring out the image. Can anyone suggest another method of processing this image or similar images as ive got a lot of photos that look like this and go blocky ?
