I show a way to cut a medicine cup to hold a piece of vellum or paper at a consistent angle in front of your flash.
Step 1: Materials
*A squarish piece of vellum about 2 inches on a side. I imagine other translucent material would work too, but vellum works well because it's lightweight and stiff. I used a piece salvaged from a fancy invitation.
*Clear packing tape
*A piece of paper about the size of a 2 to 3 inch post-it
*Something to cut with (scissors, exacto knife)
