Here are some guidelines for supplying images...
In order for an image to be usable, it must be scanned at a resolution of
2400 DPI or more; 1800 DPI if it's a monstrously large coin. Ideally
we like to have the coin at least 2000 pixels in width. The images on the
Exact Change DVD are 800x800, but we collect the originals at higher resolutions
in case there is an increase in screen resolutions in the future.
You needn't worry about scanning an image at too high of a resolution.
We store images in JPG format, but we can import images
from almost any file format. If you have a choice of file formats, JPG
is recommended because the file size is small and the file uploads much
faster than other formats.
Do not attempt to enhance the image after scanning it by adjusting the
brightness, contrast and so forth. We prefer images raw as they come out
of scanner. We can straighten the image and make any photographic
correction that may be needed. There is no need to be concerned about the
background (the area around the coin).
On many flatbed scanners (but certainly not all) the image
will appear better if the coin is scanned up-side-down. The image can
then be rotated 180 degrees to turn it right-side-up. The reason for
doing this is so that shadows are cast from the upper left to lower right,
rather than toward the upper left corner. If you're not sure which way
works best, try scanning the image upside-up and upside-down. rotate
the upside-down image to make it right-side-up. If you compare the two
images, you'll probably find that one looks much better than the other.
