What Is the Best Megapixel for a Camera?
-
High Megapixel Capability Equals High Resolution
-
Resolution refers to pixels per inch (ppi) of an electronic image. The higher the ppi, the greater the resolution. Images with greater resolution allow you more editing options, such as enlarging an image while maintaining its clarity or cropping a particular element of an image, than do their low-resolution counterparts.

High Resolution Equals Large Electronic Files
-
The higher the resolution of an electronic file, the more information that file contains; therefore, high-resolution images are large files. This does allow for image-manipulation opportunity, but for the average consumer, these large files sizes can make uploading files to a computer or emailing the occasional photo a cumbersome activity.
Bottom Line
-
Professional photographers will likely desire--and will also likely have the necessary equipment, such as computer memory to store large files--a camera that has high-resolution capability. For point-and-shoot photographers who desire the ability to quickly share photos with friends and family, a lower-resolution option is a more ideal choice.
