Minimum Specifications

* The resolution should be calculated from the dimensions of the object. See Samples for more information and example images.

** Whenever possible, capture at 48-bit RGB (for color, monochrome, objects with stains or marks) and save at 24–bit RGB.

Samples

The best practice is to have at least 4000 pixels on the longest edge. However, when the original object is small, as is Fig. 1, the project manager should weigh the relative benefits, considering such factors as the maximum optical resolution of the equipment, file size, and server space.
