I use a 40 watt LED gobo projector to project light through a gobo. The "gobo" is a glass or metal disc with a maximum 40mm image. The other end of the projector is an adjustable lens for focus and size. I would like to project images captured from photos for everything from creating room textures to projecting images and logos for individuals and businesses onto walls and screens among other surfaces.
The metal and glass discs are expensive to have made so I search for a way to achieve the same effect with perhaps photo slide transparencies or film.
I need to get the digital photo onto an opaque substrate that can have light shined through it with zero bleed through except, of course, the image desired.
Any idea or suggestion on what the process and material would be?
