Nice of you to ask. I took pictures three nights so far this week. I am thrilled with my pictures from Monday. I am going to scan some of them---my first 6x24 scanning.Originally Posted by Juergen Sattler
You misunderstood me entirely. No one requires that you find every topic interesting. No one requires you to read all posts. No one requires that you answer posts. As I said in paragraph 1, the quiz was supposed to fun; if not, no one requires you to do it. If you were shocked and appalled that a quiz appeared in my post, I suggest you read titles of posts a little more closely.Originally Posted by Juergen Sattler
I was hoping the word "quiz" in the title would bring the kind of poster who thinks a little quiz on perspective might be fun. Paraphrasing Scarlett O'Hara, "Quiz fun?!? Fun for teachers, you mean."
Maybe I should have included the word "math" in the title? Would that have helped you steer clear?
Here is another confusion of yours, but it is shared by many others: I never said I worry about mathematical precision while taking pictures. As it happens, I do no math worth mentioning while taking pictures. The math in my post is for camera design and lens choices almost exclusively. Math sometimes helps me figure out what to build, buy, or bring. When I am out there shooting, I use what I brought and do the best I can. At that point, math is too late.
The reason for math is that is often faster and easier for me than trial and error. I also enjoy it. But the amount of math we are talking about here is about five orders of magnitude less than what appears in some photography books, so I am just a math dabbler by comparison to some of the heavyweights.
