Made a bunch more pinhole cameras with the tins I accumulated over Christmas. My new cm ruler has half millimeter measurements on it and I’m hoping therefore more accurate. My astigmatism makes that iffy, but still. But I now have more cameras than I can carry in my one suitcase and now I need another method. I need to divide them up by f/ or something since I seldom need the total range all at one time.

I’ve decided I should probably take a photo of the same object in the same place under same conditions with every camera and then tape the negative to the camera to remind me of its properties. That would probably be helpful.
