  time lapse question.

  Posted by Luke Pearson on July 9, 2007 at 5:42 pm

  I want to shoot a time lapse shot of the sun setting on a college campus; campus going from sunlight to street lights. How can I shoot this without having to adjust the f-stop every so often? thanks.

  Try using a series of ND filters. Do a test to find your exposure with the street lights (say f2) and your exposure at full sun (say f16). This is 6 stops. Set your camera to f2 and put 2-n.9 filters in front of the lens. Remove n.3 every time you want to open up a stop. ie n.9+n.9=f16, n.9+n.6=f11, n.9+n.3=f8, n.9=f5.6, n.6=f4, n.3=f2.8, clean lens=f2
