This is the fifth in a series of posts about building a bokeh simulator. This series starts here. In the last post, I compared simulated defocusing to the real thing with the Sony 135mm STF lens. Now I’m going to do the same thing with teh Zeiss 135mm f/2 Apo=Sonnar ZF.2. Here’s a sharp image with an a7RII… [Read More]
Comparing real and simulated defocus blur — Sony 135 STF
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]
