They only seem complicated at first. When you dig into them, they're even worse. Ay yi yi.

You're doing better than some of us then. Sometimes I don't even understand what *I'm* saying.

The problem was the teachers, not the subjects. Too many teachers just don't have the enthusiasm.
But I digress. Photography is a technical field, as well as an arena for artistic expression. Lots of it doesn't make sense without some arithmetic and visualization and exposure to principles of composition. We can mostly skip the calculus and pre-calculus and quantum optics and chaos theory, but a little geometry and trig creeps in unannounced. At least we needn't worry much about chemistry now.
Any technical field is distinguished by its jargon, its specialized language. We learn the field by learning the language. We learn acronyms like FF, MF, DOF, FOV, AOV, YMMV, etc; and common words with specific meanings like normal, register, perspective, long, stop, bayonet, index, fanboi, etc.
PFC (PentaxForumsCom) is an ongoing seminar on photography. I've been shooting for 5+ decades, but I've learned a sh!tload right here in the last few years. And I know I have a sh!tload more to learn. It's an infinite process. Long may it wave.
