At first, you might not think this applies to photography, and it certainly doesn’t apply quite the same as in something like drawing, but it is still a factor. Who among us has used a camera and not realized until looking at photos long after the fact that there are objects in the scene that you never noticed and probably wish weren’t there. When looking through the viewfinder the brain tends to edit out everything that we’re not focusing (mentally) on. I’ve had plenty of pictures spoiled by a random piece of trash in a gutter, or some strange object appearing to sprout from the head of my primary subject.
Fine. But yesterday this was driven home again in a new form. I’m getting better and looking at everything I see in the viewfinder, but everything has to mean EVERYTHING. Those of you in the Boston area may have noticed that we had a fairly brilliant sunset on Monday. I got home just as it was about to fade, and wanted to take some photos out my back window….I’ve been eyeing the tree/house skyline back there for a while and thinking it could make a nice dark foreground to an evening sky. In my haste, I forgot that my prior use of the camera was in a band/club setting. That setting had about zero light which means I was on a high ISO, and I forgot to check the setting before shooting my sunset. Of course, among the many pieces of information available to me in the camera viewfinder is the current ISO setting, but I never even looked at it. I composed, shot, liked what I saw on the back of the camera, sat down to watch MNF and didn’t realize my mistake until the light was long gone. The shots aren’t terrible, but ISO noise from shooting at 6400 instead of 200 isn’t exactly what I was looking for.
There are so many things to think about while operating a camera….someday I’ll do them all instinctively. For now, photography, like the rest of my hobbies, is often a humbling experience.

I can relate to taking pictures and then finding that the settings are totally off. Way too many shots takes on a bright sunny day ruined by having the ISO at 1600. Having spent my youth dealing with film and playing around in the dark room, using a digital SLR has been like relearning photography all over again.
Sometimes when we’re busy composing something in a picture, something unexpected occurs which adds another element to the photograph. (Kind of reminds me of what happens in some of my chess games, though with not so nice results.) Take a look at this photo I took. Sorry I’m HTML challenged an can’t figure out how to make a link.

I had been playing around with settings and doing different stuff during the sunset. I was playing around with various silhouettes against the sky and the water. When I took this picture I was concentrating on the two cyclists. It wasn’t until I looked at the picture afterwards that I noticed the dolphin that had popped up at that moment. The couple didn’t even notice it either. As I looked at the picture I started thinking, “too bad I centered the couple instead of having them off to the left”. Though if I had put them to the right I would have totally cut out the dolphin all together.
The irony of the picture is that when I was trying to photograph the dolphins during the day I ended out with lots pictures of fins, tails, or splashes. It’s hard to anticipate when and where they’re going to pop up next.
