For those who shoot with antique lenses but are missing Waterhouse stops, photographer Markus Hofstätter has put together a tutorial that shows a couple of ways that shooters can create their own.
It was a normal Saturday afternoon in November when I walked into a flea marked. I met some friends there, looked around a little bit, and in the end I bought this Gasc and Charconnet 500mm Petzval lens in the hopes that I could bring it back to life.
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.
