Not wanting to exclude anyone from Project 52-2-13 Exposure: Multiple, I would suggest that we allow:
1. Pictures done multiple exposure in camera.
2. Pictures (low light) done by the ghetto method of a long timed exposure (keeping the lens open and creating multiple exposures by putting a piece of cloth over the lens periodically (or some variation).
3. Taking multiple exposures and combining them in PostProcessing software but steering away from HDR.
This should allow everyone to participate. Let me know if there are any objections to the change.
