I am a huge fan of Dog Schidt Optiks. The strange optical artifacts and unique flaring gives these lenses character. And most of these artifacts are incredibly hard to replicate in post which makes them just that more interesting. If you look at a video like Richard Gale’s festival of 50mm lenses you get a good sense of what this is all about.
Earlier this year, during the RnD period for a project im wokring on right now, I updated my Spotflare toolset to add some of these unique characteristics. Most of this will eventually go into a public release of Spotflare V3. Everything is done procedurally using expression nodes.
Here are some videos of the RnD progress:
Stay tuned for more about Spotflare V3.
