What is thinking?. Right brain, left brain? I like what Cynlee says... you must not threaten yourself with your art. Take a spirit of criticism to heart and you'll find it will sustain frustration nicely. You may, for technical reasons, as Wolfsnap said, - need to tell yourself WHY the photo you took was good (or bad!). Also...'good' is not the same as 'pleasing to others'. Just recently I got an amazing amount of feedback from a 'pretty' water reflection series that I just came across (1-2-3-4-5-6 bang - all in a bag). Happy!? not really....overwhelmed and frankly a bit bored by the same kind of response (No offence meant). My recent peeling paint stuff is not pleasing to others for some reason (BUT I LIKE IT... LOL!). I'm learning more from this however (both series incidentally are as clear and colorful as each other). I'm learning..(1)people like an expression of space when viewing a photo also (2)There are professional intentions & artistic expressive intentions (which can overlap) (3) Photography and writing for me is part of who I am (squeezing out answers when life gives tight spots and personal challenges makes me learn). (4)Some people have great scenery to shoot, others not. Is the best photographer always going to be the most pleasing! Or is it going to be good?
