Shooting Landscapes by Moonlight

One of the great advantages of a digital image sensor is its extreme capability in low light. With a digital image sensor, you can work at light levels far below what is possible with any type of film. This sensitivity opens up a lot of photographic possibilities, such as shooting landscapes by moonlight. However, while your camera can be very sensitive to low light, your eyes might have trouble getting by when shooting in the dark. As such, you’ll need to employ some specific procedures when working in low light.

Canon has positioned their new Rebel XSi at the “entry-level” end of their product line. But it’s getting increasingly difficult to divide digital cameras into “entry-level” and “mid-range” and “high-end.” In the early days, there was a single distinguishing feature that made it simple to tell what market a camera was aimed at: the image quality of an entry-level camera was markedly different from a high-end, “pro” level camera.

The promise of compressed raw files, of course, is that they take up less space and allow you to store more images on your card. Data compression algorithms fall into two categories: lossy techniques, which degrade the quality of your image; and lossless techniques, which reduce file size without affecting image quality. Nikon users often ask whether the compressed raw format is lossless or lossy, so I decided to look into the question.
