I have done a project for university using shots where I have created my own "bokeh" (not sure what term to use but I have altered the traditional out of focus circle from a light source).
NOT MY IMAGE but this is an example of changing the traditional out of focus circles:
I have done this in my video but I was wondering if you could help me look at the actual science behind this effect so I can add a part to my presentation of how this effect actually works and why.
If anyone has any information as how to refer to this effect as well it would be helpful as it is not particularly well written up online so I don't know how to refer to it.
I made my masks not as images but as words so there were gaps between the letters almost making the "filter" act as a diffraction grating. Not too sure how to explain this in so many words though.
Thanks
