I am taking some documentary photographs of a new sundial concept and I need a little help.
I recall reading several postings in the past that referred to using a point light source to simulate the sun. This would be very helpful in simulating conditions such as solstice and equinox declination, as well as any desired time of day. Accomplishing these various conditions outdoors is proving very difficult (and hot!), so I would like to set up an indoor photo shoot with a common backdrop. This way I hope to create the ideal times and declinations for my instruction sheets.
Does anyone have any suggestions for a good point light source to use? I have tried several flashlights and lightbulbs and I keep getting fuzzy shadows. The best "point of light" I have found so far is a mini MagLight flashlight with the reflector assembly removed...but it is not as bright as I would like. Any ideas?
