12 Tips For Taking Great Digital Pix 6


Work the Histogram
Sometimes images that seem fine on your camera's view screen are not so good once you get them into the computer. If your camera can display a histogram--a chart showing the distribution of tones in your image--then use it. The ideal histogram has the form of a bell-shaped curve. On the left side are the pixels that record dark tones and the right are pixels with light tones. (The far left of the histogram, the 0 point, is for pure black; the far right, at 255, pure white.) A histogram clustered too far to the left is probably underexposed; too far to the right, overexposed. You can adjust light levels in image-editing software, but you're better off using the histogram as your guide and setting the correct exposure in the camera.
