[QUOTE="Don Kuykendall_RIP, post: 256871, member: 6277"] What aperture and shutter speed you shoot is more dependent on what you are shooting and what effect you want from the shot. About the only rule you need to really learn is that if you are shooting handheld you will need to shoot fast enough to negate movement of the camera. [I][FONT=Verdana]The Reciprocal Rule[/FONT][FONT=Verdana]--perhaps the most used “rule of thumb” in photography. It is used to determine the slowest shutter speed you can safely use while hand holding your camera and still prevent camera shake. It states that when hand holding your camera, the shutter speed should not be slower than the reciprocal of the effective focal length of the lens you are using. So, if you have a 55 mm lens, then the reciprocal of that would be 1/55, which means that the slowest shutter speed you should use would be 1/55 seconds.
