None of this is particularly difficult, but the printed masks tend to be pretty miserable quality.

Prof, what do you think of this paper?


I know you are very familiar with both optics and 3D printer. Could it be a poor mans approach to use spray paint with the right 3D shape (elevated)? The paper I point to is for more complex things, but gives an idea of ...the idea.

My motivation is that I really want to use material that does not produce diffraction, haze, so the filter may not be perfectly even, but I am not thinking that much of specular highlights, but of very smooth out of focus areas
