Viewfinder, flash and other features Digital cameras use optical or electronic viewfinders or a combination of both. Some come with oversized LCD's which function quite nicely as a display. Preview screens allow you to see whether you got the shot you wanted and to identify which images to erase. Some times LCD monitors are an add-on option but often their addition makes the camera quite clumsy to use. Once you've used a camera with good preview capabilities you'll have a hard time doing without them.
Most cameras come with a built-in flash.
Only some offer red-eye reduction. Some digital cameras offer sound and limited full-motion capabilities. Look and Feel How a cameras looks is subjective but how it feels can definitely contribute or detract from the picture making process. Many of the earlier digital cameras were basically big heavy boxes that were difficult to hold. This is no longer the case, and many of the cameras on the market are relatively light and easy to hold.
