I've used the line "I just take pictures" many times on the forum and tell the same thing to people I work with. It is a simple way of saying how I see what I do. Over the years I learned to see without having to overthink a situation. While many of my images may follow all the "rules" of photography, they are not done with rules in mind. If I see something I like, I shoot it, then I look at it from slightly different angles. If I saw the image in the first place, chances are it was close to being right. I look past an image to see what's behind it, if I wait a few minutes will it get better without me moving, sometimes yes other times no. Everything I look at I see a picture, the majority are boring, but it more based on how I see the light than it is on dividing an image into segments. If the light shifts while I'm setting things up to follow a specific set of rules, what I originally saw may be gone. This is why I use the simple "I just take pictures"
When I'm shooting for a client I do think ahead as to where I would like to shoot from, many times the only rule in place is "you can't shoot from here" I may or may not follow that rule, depends on their security rule. The different fields of photography aren't always set up for the rules of thirds. I crop images the way they look best, they may be tall or wide and thin, subject heavy loaded at the top, bottom or side. If it's a square that works, a square it is. The bottom line is that while the rule of thirds, or any other "rules" may occur in my images, I haven't intentionally thought about it, I never have. As I mentioned, I had never heard of it before this forum, I was never told there were rules to photography at anytime in my life. I learned from just taking pictures, lots of them, I have shot my share of garbage, but I gathered experience along the way.
One of the biggest downfalls I see that learning camera owners have is stressing out by overthinking the pictures they want, and coming away with nothing. If you see it, just shoot what you see, chances are it's right. It's also less frustrating.
