Ins and Outs of Slide Film


I know this might sound like a silly question, BUT when shooting on slide film what exactly do you get back from the photo lab when your roll of film is developed?

  You get mounted slides.

  Slide film is called "positive" film, because, as Kerry said, you get the actual results in the form of slides you look at via a slide viewer or projector.
Many folks - amateur and pro alike - feel that the best results can be achieved with slide film. In many ways I agree - great color, sharpness, etc. However, your exposure must be "right on" when using slide film.
Generally, with negative film, there is a fairly wide exposure latitude. You might have up to nine stops, based on lighting, etc. Typically, you can over-expose up to about 3 stops, under-expose up to 5 stops. That's a very wide range. Of course, you need to experiment and check your results for the exposure you like.
With slide film, you can generally use 1/2 stop over and 1 stop under. So, you can see that there is less exposure latitude with slide film. You must try to be "right-on" the first time.
One of the nice things about slide film is that, because you get slides (also called transparencies), you can really get great results when you try bracketing.
When you bracket using negative (print) film, always bracket by at least one full stop (over and under). That's because, with most of today's computerized printing processes, the computers will try to "correct" the small differences of, say, 1/2 stop bracketing. In other words, you may not be able to see the effect. Always alert your photo-finisher to the fact that you've bracketed exposures when you use print film.
Hope this helps.

  "Normally" you get back mounted slides, assuming you are shooting 35mm. However, some better film labs will give you back the processed roll of film uncut and unmounted if you so desire. Some will give you the option of plastic or cardboard mounts, numbered or un-numbered, etc.
