Cafe culture goes way upmarket

Low-light photography offers a whole suite of challenges in either optical or digital, and your solutions to these tests might be different on different days (or shoots). It all depends what results you want: the pro might want a tack-sharp image without grain, because s/he is more than likely shooting for a brochure. The amateur will want a good, clear shot, and can afford to live with a little grain, since the image isn't going to be published, much less at large size. Either way, your choices (your solutions to the challenges) will define this project: stop the action, or "correctly expose" the background, produce fantastic depth-of-field with blurred figures, or accept a little grain in the shot...? It's all about film speed, aperture, and shutter speed. Here's a few ground rules to help you make the decision: high shutter speeds will stop the action (no blurry figures), but you'll need either (or both) bigger apertures or faster film speed to get those fast shutter speeds. Big apertures cost you depth of field, and fast film speeds give you grainy images. Long shutter speeds give you blurry figures (anything that might be moving), plus the probability that you'll get "camera shake" during the exposure, which means the whole shot is blurry. Somewhere among all those "downsides" is a happy medium, and depending on what you need or want out of the finished shot, you'll make your decision. Photo by Mel, 2009.
