What slide projectors are most reliable for on screen ads?
Best place to buy?
Anyone willing to share how they are making their own slides?
I'm sure it can be done with transparency's and a printer?
Thanks

You can make your own B&W slides pretty easily with a 35mm SLR camera, a makeshift copy stand, and Kodak "Ektagraphic HC" film. This is the same Kodalith material that is used for making negatives for offset printing--i.e. it is a very dense, high contrast negative material. Motion-picture sound recording film also works. You can develop either of these at home with only a developing tank and a changing bag. Essentially, you create the artwork as black-test-on-white using a laser printer, etc. You photograph it and develop the negative, which produces clear text on a black background. This is a simple and cheap way to create decent-looking slides.I've been happy with both Telex projectors and Kodak Ektagraphic projectors. Some people have posted that the Telex models hold up better over time. I haven't had trouble with either brand.
Regardless of the projector type, be sure to use glass slide mounts and "flat-field" projection lenses. Avoid zoom lenses if possible. Get the bright EXW bulbs, not the cheap and dim bulbs. Dim slides look awful on large screens. Consider a dual-projector system with a dissolve unit for smooth crossfades.

Don't go buying slide projectors until you have checked over the contract of whoever you are going to sign up with for onscreen ads. Most of them provide the projectors for you.If you have a choice, go for the Telex units. I've never had one fail.
