Highlands Ranch Photo Club Meeting of August 8, 2006
Featured Speaker: Richard Bruner on Low Light Photography
A tripod, remote release cable, timer and image stabilizer are good ways to help prevent shaking. Fast lenses are good for night photography, but can be very expensive. A good compromise is a 50 mm lens.
Some digital cameras have a "long exposure noise reduction setting" that can be used to reduce errors that occur during long exposures. ISO is a standard for film, but the ISO setting on digital cameras is not a standard and may not work the same with different manufacturers. Some cameras have a long "shutter lag" that can increase the chances of a blurry image in low light situations. Auto focus does not always work well in low light situations.
Some techniques for low light photography include exposure bracketing, and painting the foreground with a flash.
Higher film speeds contain more grain. Consider using a lower speed film and "pushing" the film. 100 ASA film, for example, can be shot at 400 ASA, but the development time must be changed to compensate. Slides usually work better than prints because automatic print machines sometimes get the exposure wrong with low light shots. Reciprocity law failure is the loss of exposure sensitivity in very short and very long exposures. It changes the way film behaves, causing color shift in long exposures. Artificial light can also cause color shift.
Consider turning off automatic white balance on digital cameras during low light photography.
