This is the fourth in a series of posts about building a bokeh simulator. This series starts here. I wanted to get an idea of how simulated defocusing compared to the real thing with the Sony 135mm STF lens. I took this sharp image with an a7RII at f/11: Then I set it to the… [Read More]

How to capture OOF PSFs
I’m going to be needing out of focus (OOF) point spread functions (PSFs) from various lenses for my bokeh simulator project. Here’s how to capture them, for which I am indebted to Professor Hank on DPR. All credit to him. You’ll need a dark room — thankfully, not a darkroom, just a room that’s dark…. [Read More]
Simulating Zeiss & Nikon 135 bokeh with real and idealized PSFs
This is the third in a series of posts about building a bokeh simulator. This series starts here. I took the out of focus (OOF) point spread functions (PSFs) from the 135 mm f/2 DC Nikkor and the 135 mm f/2 Zeiss Apo-Sonnar ZF.2, and put them into the simulator. You will note that the… [Read More]
Simulating Sony 135 STF bokeh with real and idealized PSFs
This is the second in a series of posts about building a bokeh simulator. This series starts here. Yesterday I did some bokeh simulations of an apodized and conventional lens using calculated point spread functions (PSFs). Today, I want to look at real PSFs. I realized that I had some of those, generated which I… [Read More]
Building a bokeh simulator
This is the first in a series of posts about constructing and using a bokeh simulator. If you want to easily navigate to the other parts, at the bottom of this post (below the comments) you’ll find pingback links to each of them. I’ve been reading a lot of controversy about lens bokeh, and it… [Read More]
