When you're viewing an image in the LCD screen, you need to know what to look for. Here is a brief checklist of things you must pay attention to when reviewing your work on the screen:

Brightness. I want to know as soon as possible if I'm exposing the scene too dark or too bright.

Composition. I quickly scan the edges to see if any part of my subject is being cut off. I also look for slanting horizons, an overabundance of negative space, distracting elements, and other compositional faux pas.

Major blur. If I see major, unintentional blur, I know to immediately try the shot again. The second time around, I work harder to ensure that the camera is as stable as it can possibly be.

Minor blur. Many cameras let you zoom in to view one portion of the image. If you're unsure about the sharpness of a photoand you have a camera with this zooming LCD feature and have sufficient time between shots to look more closelyuse this feature to zoom in on one particular part of the photo and view it on the LCD screen. This will help you get a better idea of overall focus.

The one thing you have to watch out for when viewing images on your screen is what we call LCD distraction. This is when you are so busy reviewing the images you just took that you miss an even better shot. If you decide to review your photos while there's still a chance for a subsequent photo op, keep one eye on your subject at all times. If you have a friend nearby, you might also ask him or her to watch the subject for you, alerting you when anything interesting begins to happen. This comes in handy when photographing kids, whose attention can drift from time to time, only to return to the camera when you least expect it. Better yet, refrain from closely reviewing your images until later.
