Exposure and shooting modes

By , March 22, 2010 1:16 pm

I’ve been reading Bryan Peterson’s book “Understanding Exposure” and he states that “A correct exposure is a simple combination of three important factors: aperture, shutter speed, and ISO.” He refers to them as the photographic triangle. I have also been reading on lots of photography sites on the web and numerous other photography books. There is a wealth of information out there. The exposure is the amount of light that reaches the sensor in your camera. The first step in shooting and controlling exposure is to choose a shooting mode. The T1i has shooting modes that range from totally automatic to  totally manual, and then some in between. The shooting mode determines how and what kind of exposure settings are set and who sets them, you or the camera. I have been concentrating on the Creative Zone Modes.  So next I’ll zero in on the aperture, shutter speed, and ISO so I can get a better understanding of what it takes to get a good exposure. Then I’ll try to post about the specific shooting modes.
