These devices outsold conventional 35-mm SLR cameras for the second year in a row. It's not hard to understand why digital cameras have become so popular. This translates into a substantial time improvement and offers a valuable competitive edge. It also eliminates the cost of film development, and perhaps even more important, it allows EDI-ready appraisers to transmit the entire appraisal report with photos to lenders and clients. Perhaps the single biggest indicator of picture quality is the camera's image resolution.
Resolution is measured in pixels or dots.
The image quality of the photo will be sharper with a camera that offers higher pixel resolution. In some cases, higher resolution doesn't always translate into better photos. Picture quality also depends on the quality of the lens and the image-capture chip. On the downside, the file size of high-resolution images becomes much larger, which means that the transmission time required will also dramatically increase. With all digital cameras you have a choice of either built-in memory or memory cards, that store the images you take until you can download them to your computer.
