Slide Mounting Equipment
If you want to view your slides they need to be put into slide mounts. These are the thin items that hold the slide inside of them, allowing you to pick the slide up by the mount's outer edges. Slide mounts are generally made of cardboard, plastic or glass. Slides can be inserted into plastic mounts either by hand or machine. To mount them by hand, you have to cut the roll into separate frames. To mount the slide, you slip the frame into an opening on the edge of the mount. Make sure the slide is straight and no light can pass between the edges of the film and the mount. Slides are inserted upside down and backwards in the projector or tray.
A good slide mount should let your slide breathe, protect it from dust, scratches and fingerprints and seal and hold it firmly. Slide mounts come in various sizes, thicknesses and styles. Make sure the slide mounts you buy are compatible with your projector. Mounts generally cost less than a dollar each.
