Determining Fronts and Backs of your slides Video

You need to determine the fronts and backs of your slides. 99 times out of 100, the front will be the side with the logo on it. A logo is the name of the film used or the processing company such as Kodak. The back side will only typically have a number or date on it. The front of the slide has the emulsion of the film. This is the side that gets exposed with light coming through the lense and the aperture.
