On the other hand, without expert photographers as well, there would be nobody to learn from.
But, from time to time, it can be very useful to see images that have been perfected, to the satisfaction of an experienced photographer, so that folks can see how things should or can be done. If you scare off more accomplished photographers who are rightly proud of their results, you will never have anything to aspire to.
I'm willing to bet that there are some here who would criticise an Ansel Adams image, just because they feel that no image can ever be perfect in their eyes.
Folks may not like how an image has been processed but, just as Martin seems to revel in soft old tech images without too much criticism, I would rather see well produced, clean and sharp images. Different strokes for different folks.
