Most common digital cameras have three settings for RESOLUTION. Depending on your model, will depend on the maximum resolution a picture can be taken at. Most common cameras have three settings and are usually referred to as BASIC, NORMAL, and FINE. Basic being low resolution, normal being medium resolution and Fine being hi-resolution. The easiest way to tell is the fewer the pictures that can fit on the camera per setting the higher the resolution. Ex: Basic might let you take 72 pictures where as Fine might let you take 3 before your camera is full (this varies depending on model of camera and size of media in camera). For most printing purposes you want the highest resolution for your pictures. The maximum actual size of the picture would still depend on the final resolution of the photo if it has to be enlarged. For large pictures or Large Format Digital Prints it is recommended to take a photo using a regular camera. Then bring in the developed photograph so that we can scan it at a higher resolution to achieve a larger size print.
