difference between slides and negatives


What is the difference between 35mm slides and negatives? I have 8mm slides that I would like to convert for a Christmas present and none of the converters that I looked at included 8mm. It only mentioned slides. Are they referring to 8mm at that point?

  A slide, or 'positive' is a type of film where the image is captured as the eye/camera saw it in terms of colors. Slides are generally used when the goal is to use a projector to view images rather than making prints, although many pro photographers also used slides for publication.

Negative film captures the 'opposite' in terms of color and brightness. Negative film is used for printing; the paper is also 'negative' in that it will produce the 'opposite' of what it sees, i.e., a negative plus negative paper results in a 'positive' print that is true to the original scene.

'8mm' is a film size, as is 35mm. The most common use for 8mm film was for home movies, and in that case it will be on a reel (for a movie projector). 8mm movie film will be positive, as explained above.

If you have 8mm movie film, your best bet is to pay a photo processor to convert it to DVD.

If you have 8mm slides, then they must have come from a rare, unusual camera. If the slide mount for them is the same size as 35mm slides, then you can scan them with a film scanner that accepts 35mm slides. If not, you will have to make up a holder from thick paper stock that you can temporarily tape the slide to, so that it will work in a 35mm scanner.

If, after all this, you're still not clear on what you should do, your best bet is to bring the film/slides in question to your local camera shop and ask them what should be done.
