Very briefly, slides are positives, which means that once developed, the film displays the true colors of the picture. Print film, once developed, displays a negative image, which requires another step - putting onto print paper - before you can see the true image.
The advantages to slide film are :
- it is generally a lot cheaper,
- you display the original image, which inherantly has more detail (unless you blow up your prints to poster size)
- Slide film tends to have slightly better grain and color than print film at the same ASA rating.
- Pictures tend to have brighter, prettier color performance, as you deal with projected light, rather than reflective light.
- Slides are less easy to look at without a magnifier, projector, or viewer
- If you want to make prints, the results are usually a bit too contrasty. This seems to be a limitation of the processes and paper rather than the film itself.
- Slides have virtually no tolerance for error. You can be off by 1 or 2 full stops with print film, and the development process will correct for it when transfering from negative to print. This step does not exist for slides.
