Exposure. In issue No.1 of The Art of Photography, photo enthusiasts were introduced to the nine fundamentals of photography that are essential towards creating better pictures using your Canon 35mm SLR cameras. In addition, all enthusiasts were also taught how to "see" with their eyes before clicking the shutter button to record that image permanently on film by learning the three important questions professionals always asked themselves. In this issue, I will focus on the first fundamental, that is exposure. What is exposure? In photographic term, exposure is an image that has been recorded either on film (conventional photography) or on a CCD sensor / PCMCIA card in digital photography. The recorded image can be of any subject matter but the most important aspect of any exposure is whether it is correctly exposed or simply too bright (overexposed) to register any detail or too dark (underexposed) to see anything at all. That, basically sums up what exposure is all about in photography. But how do you know whether your Canon camera's built-in metering system is reliable enough to determine correct exposures? You don't. All Canon's EOS AF 35mm SLR cameras have built-in multiple metering systems but it is still up to each user to know the limitations of the camera's built-in metering systems and determine how much they can cope with each metering option for every photographic situation. Doing this will go a long way in determining the results of all your images that will be photographed with your EOS SLR camera in having correct exposures or otherwise. The most versatile of Canon's metering systems is none other than the multi-segment Evaluative Metering mode. Depending on which EOS camera you are using, Canon's Evaluative Metering ranged in several versions. For more information on Metering, please click here. << Back to Main . 1 . 2 . 3 . 4 . 5 .
