I set my instrument for Ampersand Pond, sighted the picture through the ground glass, and measured the focus. Then I waited for a quiet moment, dropped the plate, moved it carefully forward to the proper mark, and went around to take off the cap. I found that Ialready had it in my hand, and the plate had been exposed for about thirty seconds with a sliding focus!
I expostulated with myself. I said: "You are excited; you are stupid; you are unworthy of the name of photographer. Light-writer! You ought to write with a whitewash-brush!" The reproof was effectual, and from that moment all went well. The plates dropped smoothly, the camera was steady, the exposure was correct.
Six good pictures were made, to recall, so far as black and white could do it, the delights of that day.
