In this thread on DPR, the original poster reported some creative and useful work on quantitatively measuring filed flatness and tilt. During the discussion, he made reference in passing to using the focus peaking feature of some mirrorless cameras to rapidly check for lens tilt.  I was intrigued. In the past, I had some success… [Read More]

This post is part of a series about some experiments I’m doing combining space and time in slit scan photographs. The series starts here. I am experimeenting with the slit scan technique with different weather conditions.  

This post is part of a series about some experiments I’m doing combining space and time in slit scan photographs. The series starts here. Yesterday, I showed a bunch of renderings of the same image sequence using a vertical synthetic slit.  I’ve set up the program to simulate a horizontal slit, and here are some… [Read More]

This post is part of a series about some experiments I’m doing combining space and time in slit scan photographs. The series starts here. Now that I’ve got the Matlab parallel processing going, it’s easy to produce lots of different renderings of the same capture set. There’s a downside to that. How to choose between… [Read More]

This post is part of a series about some experiments I’m doing combining space and time in slit scan photographs. The series starts here. When you take a set of 10,000 5200×3500 pixel images and run slit scan simulations against them, there are a lot of options: What image to start with. Which way to… [Read More]
