Projecting onto Glass

keftaparty

Hi,

I did some experimentations and shows projecting on frost plexiglass.

I can give only one advice:

Try every material in the exact situation it will be used !

I had one very bad experience: I tried one material with a long zoom projector, the image was ok.

But at the end I had to use a wide angle projector. The center of the image was perfect, but all around the light was arriving on the surface with too much angle and was impossible to see !

Also take care to the angle the "spectators" will have, with that kind of shiny surfaces you get very differrent results depending on the point of view.

Have fun !

Best

@Skulpture - It sounds like a really interesting project!

Given the situation, I would be inclined to go towards the really expensive films. In small quantities they may be affordable and they will provide a good projection surface. Most importantly, they won't affect how the viewer sees what's inside the case. I would think that would be the #1 consideration from the museum's point of view.

Cheers,

Hugh

@skulpture. If your prerequisite is to be able to see a sharp image and still have the glass to be transparent, there is really only one solution and it's expensive: HoloPro. Similar glass was used in the movie Minority Report.

I installed and use an 8' wide HoloPro glass panel at my company for presentation purposes and it's amazing. To get clarity and transparency of glass, embedded holographic foil is really the only solution. Otherwise, you need to go with rear-projection film (and of course, this means you won't get the transparency.

Cheers.

this is an interesting thread. i did some searching and found this uk outfit:

lcd glass is great, but does it go clear enough for a museum setting?

All brilliant stuff thanks all!

You've all really helped me out and given me lots to think about.

@dansnodgrass the HoloPro is amazing and looks stunning but yes you are right... very expensive.

You'll also notice in the picture of the HoloPro, that the woman is interacting with the presentation. This is facilitated through the use of the VIP Interactive TouchFoil produced by Visual Planet (and not available at a store near you for about $10,000 - for the 3'x8' foil you see in use here.)

..projection on glass

ORGANIC
for the low tech end (and of course budget) try buttermilk: applied thin with a foam paint roller it will dry after approx. 20 minutes (3 time s). it's a charming. try it before applying at the flagstore ,-).
and you can accentuate the vintage look with a brush etc, get a cleaner look with airbrush (?)... just experiment!.. removes with water

PLASIC
(low end) we used to take frosted sandblast foils - they're not soo expensive and easy to remove. get some sample and try

have fun mickey
