Many intermediate to advanced cameras also include a custom white balance that al-

Even better, some advanced DSLRs, such as the Canon 40D, let you select specific hues
via the Kelvin color temperature scale. If your camera has this capability, be sure to see

when composing images in picture-taking mode. But magnifying the picture you just

e problem with LCD monitors is that they are very small, colorful, and sharp. What’s

screens, you might be misled as to the quality of your shots. In other words, LCD moni-

at the subjects face on the LCD monitor after you’ve shot a portrait. If you don’t zoom
