Dr. Hug's Photo Scanning Service

Kodachrome is Kodak's brand name, but the slide mount (frame) isn't always labeled with the name "Kodak" or "Kodachrome".

The way to determine if the slide is Kodachrome is to look closely at the film surface. One side of the film is duller than the other. Other ways to determine the dull side are:

• The dull side is the side that should face the screen when in the slide projector.
• Often the dull side is the side that has the company name and/or logo on it.
• When looking through the dull side, the images and any wording should appear backward.

You need to look closely at the dull side. You can tell its Kodachrome because it has a much more distinguished texture on its surface. Regular slides have a slight ripple on its surface. See a close-up photo of a regular slide and 2 close-up photos of Kodachrome slides below.
