Dave, I'm thinking you mean "critical" in the sense of "critiquing" your photos rather than saying how bad they are? I would like a thread where we could do that for each other -- as long as we understand that critiquing is also a matter of personal taste and we don't necessarily have to change our way of taking photos (any more than we need to change ourselves!) just to please others.
But, for example, It has helped me a lot just to see the photographs others take here at ATP. Not even getting to how our camera is set, I know there is a standard where extraneous objects, torn leaves or faded blossom should be cleaned up, and while that isn't something I always personally care for (I tend to like the natural look, dead leaves and torn petals included), when I notice now I do try to "clean up" my photos (or my subjects) more than I used to. So setting the stage for our photos is one area where critique is helpful.
And then there are all the other areas of how we use our cameras to record our subjects: our ways of focusing, lighting, etc.
Yes,
. This type of critiquing would be a good thing!
