A minute of contemplation (literally)

The advantage of pinholes is that all you need is patience. I took my Canon AE-1 into this tropical arboretum before and had a difficult time because of the low light. The light meter required a super open aperture and slow shutter speed. With pinholes all you need to do set it on the tripod and wait. Some shots took 4 minutes. I just set the shutter lock and walked away looking for my next shot. A timer was essential.
