Scanning Your Point Photos
A Guide by Mike Hill


Tools Any image management application will have all the basic tools to change an image's size, resolution, mode, etc.. I recomend PhotoShop.

Scanning a Photo Scan image at 600 dpi and at 200% the actual size (optional). This will pick up all the available details at the start. If you scan at 300 (or less) the res. will miss finer details that can not be contrasted back into view. *note:............ By scanning at a higher resolution, the image can be down res'ed and maintain better detail/gray scale/ color. (you can't replace what isn't there).
Preparing an Image
You are trying to get the best detail (information) across with as little resolution (file size) as possible. Once you have a 600 dpi file, sharpen it's contrast by adjusting the curves or levels, then change the image size to 500 inches x 500 inches and the resoultion to 1. (It may only let you resize to 466.667 inches max). Again, the resolution - 1 (pixel per sq. in.). You will see a dramatic change in the file size, but with a minimum of change in contrast, detail and color in your image. At this point you may save the file as a "Pict" file. When the save window appears, select "minimum jpeg compression, maximum resolution". If your image is in color, select "256 colors" (as opposed to 8 or 16), if it's in black and white, 16 will apear as the highest #. You may also keep the image at 300 or even 400 dpi and save it as a Pict file (with jpeg compression), however, it will be only a little better than the way I mentioned above, but will move much slower over the w.w.w. due to it's file size.
