[photo-3d] projection screen

["Joseph Valvo" <jvalvo@xxxxxxxxxxxxxxxx>]

Can't find the starting thread but this is for the person that asked about getting started in slide projection----

Need an economical beginners screen? Take a 4'X8' piece of white foam core  alligator board and cut one piece 4'X6' (or cut to 35mm slide aspect rario if you choose. Use remainder for mounting prints). Using a course 4",5", or 6" brush, paint it in horizontal direction with aluminum paint. Try to keep strokes long and straight, Let dry thoroughly then paint again in vertical direction. Make sure the aluminum paint is type that has actual aluminum particles in suspension. This is really not a paint but is a varnish medium with aluminum particles in suspension.

Want a bigger screen? Take a piece of congoleum, sized to your choice. Stretch and nail it to a rectangular wood frame. Paint as before. Hang it on a wall. You can also obtain a piece of heavy canvas material, sized to your choice, and give it a base coat of sizing or paint to reduce absorption, then do the aluminum varnish thing again. Perhaps you don't want to hang things on the walI---- I made a painted canvas 10'X16" unit for background when doing portraits. Mounted it on a a  length of 6" dia. pvc sewer pipe- put drilled wood plugs in each end then mounted it on my photo pole vault stand.

Ya, the purest will say that these are not as good as $500 silver lenticular screen! Who cares when your are just trying to have fun!!!! Remember the old piano course add--"My friends were amazed when I sat down and played"! The other choice is to take lessons and practice for 20 years then sit down and play.

For projection you can use a twin pair of projectors mounted on particle boards located one above the other. Any number of guys on the list can supply construction and application details. Or buy a stand from J. Golden.

Bottom line is--You don't have to spend a ton of money to get your feet wet! Just jump in the stream!
