Let me hit you with some knowledge.
Long exposure is another way of saying “keeping the shutter open for a long time”. This can be done for a few reasons – to compensate for low available light, as one of a many exposures for bracketing, or to capture the idea of motion on film…errr….sensor. Let’s look at all of these briefly, shall we?
Most DSLR cameras give us the ability to control how much light hits the camera’s sensor. We can do this by adjusting the aperture (size of the opening through which the light travels), or time value/length of exposure (the length of time the aforementioned opening stays open). The aperture size and length of time the shutter remains open will help determine the overall exposure of the image captured.
For example, this image was taken with an f/1.8, 50mm lens. The only available light was a street lamp on the other side of the road, diagonally across from the old abandoned gas station. Although this image was shot in RAW, I did not make any adjustments to the exposure while editing. The only thing I’ve done to this image is sharpen and reduce the vibrance in LR, as the original had a strong yellow cast from the lamp light. Despite being taken right around 9pm at night and being shot at 100 ISO, the wide open aperture and long exposure gave me plenty of data in the final image. (See the final edit of this photohere.)
Settings: f/1.8, 8 seconds
