I have to wait another two to three weeks to take the photograph I want of an old school and church. I saw the photograph in my mind a few months ago. I need the sun to set to the north of the east/west axis to make the photo. I just checked it again yeasterday afternoon and saw that the sun is getting close to the right position.
I do most of my photography in the county where I live. This is a great advantage because I can wait for the right light. I keep a small note pad in my car so I can jot down ideas and recall them later.
I don't keep detailed notes, however. I used to, but it bacame too cumbersome to keep up. I don't really care what exposure I made X photograph with two years ago.
