Wondering if you can suggest some sites or books. I want to learn how to "read" or interpret photographs to troubleshoot the technical side of the image. In other words, what am I looking for to tell if there are problems/limitations with the sensor, lens, AF, light metering, etc.
Will take suggestions on composition too, but want to focus on the above.
I am new to the DSLR way of doing things. Currently using a T2i and FF in the works. I still have my Nikon FE2 from the early 80's but looks like it is retired now. Haven't shot anything since the early 90's.
