Years ago I experimented with custom bokeh. And I really liked it. I have to admit, I am not doing things like this very often, but occasionally.
And it is neat to know.
My blog post about this has gotten a good bit more than 1000 views by now. And I would like to re-share it here for those who have missed it, by now.
And have you ever tried using this in video footage?
Check the original post for that footage.
