I'll tell you what; candids are hard, and it's even harder when you are photographing family memories! You have no time to prepare, and because you can't set people in place like objects, you end up including elements you would not want if you could choose. You also have to include a lot of things a professional would exclude, and that is hard on composition and can draw attention away from the subject.
I hate it when people pose. Everyone wants to pose. I always lower the camera and tell them to knock it off. Nobody wants to see "my Cub Scout troop in a line, smiling on command in front of the Washington Monument." I want to capture people and show them as they really are.
If I took perfect photos and left out things like our furniture, the clothes he wears, and the places we visited, they would be neater, but they would be worthless in 15 years. When I take these shots, I think about the things people love in seeing OLD family photos. I don't consider how they will look the same day, because that would be stupid. I can remember how my son looked today, without a picture.
I have tight professional photos of myself from my childhood, and they are awful, but I like the ones where my surroundings are full of things and people I recall.
If this were some stranger's kid, the frame would be much tighter, and I might have gone for the typical featureless bokeh blur. As it is, I have his mother's arms, Costco, a familiar dress, her wedding ring, that crazy hat, and the fact that we were surrounded by the usual strangers. Those things had to be in there, even if they were defects by standard rules. When his mother is old, those are the things that will make her cry.
I am impressed by anyone who can take superior shots in situations like this. I can't even imagine how sports photographers get anywhere with subjects that run and jump.
I also think criticism from people who stand around taking landscape photos, or shooting products, with all the time in the world and perfect lighting, is useless with regard to candids. It's like comparing shooting flying birds with a shotgun in freezing sleet and wind to shooting stationary targets with a rifle on an indoor range.
I should also add that "getting it right in camera" sounds great and works for JPG's, but that isn't how things are supposed to work when you're shooting raw files that are intended to have the most possible flexibility in editing. This is what I have been trying to do, based on advice from people who claim they know what they're doing. I don't pay any attention to the appearance of my files as shot, because they are not finished. I try to get the composition right and make sure I have what I need to perfect the exposure and so on, and everything else is for software.
