Here�s a quick look at how I created some homemade �petzval swirl� bokeh that mimics photos taken with the new Petzval 58 Bokeh Control Art lens.

Vignetting is a problem, however. You may have to change the size of the hole in the paper to remove this. It�s cheap, works pretty well� but at the cost of looks.
It�s dumb, I get that, but anything to get that image though, right? Here are some more example photos:

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
