Turn pictures into Photographs
Shooting after dark takes some extra measures to get everything right. Remember that the faster the lens the better; > f/4, preferably f/2.8 or even f/1.8. The faster the lens the more light gathering capabilities, and that is a must for low light or after dark photography. However, the faster the lens the more it will cost. So is it worth the extra cost (sometimes double) for a faster lens? That will depend on what type(s) of pictures you are out to capture. Not only are fast lenses a necessity for shootin
So the opening size of the aperture of f2.8 is greater than f4.
