Step 5Slide Holder
Obviously you need an image to project.
I suggest using a 35mm slide mount with either a colour slide, or an overhead transparency made to size.
Why? the denser the film, the less light can pass through. If you want to project a maximum distance, an OH image on clear transparency is the best for guerrilla art projections that require maximum illumination.
Of course, just experiment with different type of film!
As for the laser and lens, make the scaffold for the slide holder.
Using the polymorph create a slide holder simply by placing a blob, and sticking an empty mount in there. Let it set, remove mount, and instant slide holder!
Next, some tweaking of horizontal and vertical positioning of the slide and scaffold is required so that the dot of the laser is precisely centred. Don't move the laser to centre the dot!
