Challenge has finished
Ever had one of those shots that just took forever to get it right? No editing...just the perfected shot, and maybe a description of what made it hard.

Maximum number of entries in challenge:
26 exposures, at 2 week intervals at 1/1000S, f22, 2 ND filters to record the solar disc positions over 1 year. Each exp[osure at exactly noon. Camera was placed in a prealigned metal bracket for indexing south in azimuth. Camera stored in freezer in Zip lock bag with dessicant between shots, and allowed to warm for 2 hours before each exposure. 27th exposure using a meter to capture normal sky and trees, hand held, without sun image. Exacta XV camera with 35mm lens, Kodachrome ASA 25 film. Vertical angle was set by calculation to just fit image into the frame. Tilt was caused by exposing at standard time noon instead of noon based upon exact longitude. One sun image near top loop caused by indexing error when a volunteer took over during my vacation.
