The use of a photograph varies with context. Photojournalistic pictures claim to show us what really is and so we tend to look through or past the photograph, and tend to see instead what is depicted. The photograph is transparent. Take that same photograph and place it in a collection of the Best New Photos of the Year and we will tend to see the photograph itself, we'll see the design, the colors, and so on. When told that it's a good photograph we will tend to examine it on those terms, as a photograph.
Simply by directing attention this way or that with context, we can change the way a viewer experiences the photograph. "Look at this object" causes us to look through the picture to the pictured. "Look at this picture" causes us to examine the photograph as a thing itself.
Photographers, but especially novice photographers, worry too much about the photograph. Being interested in the craft of photography, and having recently learned a few things about, say, composition, color balance, lighting, they will tend to examine photographs in those terms. They have a built-in bias against looking through the picture at the pictured, and toward examining the photograph as a photograph. In particular, they tend to examine it in terms of whatever they learned most recently. Non-photographers tend, on the other hand, to always look through the picture to the pictured. They see what the photograph is a picture of, and judge the picture largely on those grounds.
If the flower is beautiful, the non-photographer will like the picture. If the color balance is off, the novice photographer will dislike the picture.
The claim is made, and I have made it, that getting photographic, technical, details right -- good composition, skilled use of selective focus, and so on -- will support and enhance the subject and make even the non-photographer like the picture better. While this is true, the subject will surely dominate. A badly lit picture of my child being charming will trump a beautifully lit picture of my child looking like a criminal, every time.
There are a lot of consequences to this.
How do all these horrible fauxtographers get clients?! Because their customers don't give a god damn about your stupid 85/1.8 lens, what they care about is that Julie takes great pictures of their kids. Maybe a little blurry sometimes, but the kids are so happy. You, on the other hand, take razor sharp pictures of sullen children, and charge 4x as much. Screw you.
Who shall I ask for critique? If you want technical details examined, ask a novice photographer. For anything else, ask.. anyone else. Just as the mom literally cannot see the technical quality of photos from the angry local photographer, so the novice literally cannot see the subject, or the emotional aspects, of a photograph.
How shall I judge a picture? Step past the technical, and look at the whole thing. Don't judge the portrait based on the lighting, judge the portrait based on whether it flatters the subject. The difference is "this type of lighting pattern is generally flattering to this kind of subject" and "this is actually a flattering portrait of the subject."
Technical details only make the picture better if they actually make the picture better.
