This is a continuation of a series of posts about blur management for landscape photography. The series starts here. In the last post, I looked at blur circle profiles that resulted from a mixture of diffraction, pixel aperture, and defocus, and compared those profiles to the blur circle limits that I had derived from approximations. In… [Read More]
Real and approximated blur profiles
This is a continuation of a series of posts about blur management for landscape photography. The series starts here. So far in this series, I’ve been talking about blur circles as if they were disks of constant intensity (digital filter designers call these pillboxes). When we’re talking about combining the blur from diffraction, defocus, and the… [Read More]
Comparing blur circles across formats and sensors
This is a continuation of a series of posts about blur management for landscape photography. The series starts here. I’ve been asked to compare blur circle sizes between simulated full frame (24×36 mm, aka FF) and 33×44 mm sensors. I picked the Nikon Z7 and the Fuji GFX 50x as the cameras, 30 meters and… [Read More]
Cost functions for optimal blur management
This is a continuation of a series of posts about blur management for landscape photography. The series starts here. This is quite a nerdy little post. If you aren’t interested in the mathematical details behind deciding the best way to manage blur you should probably move on. To search for an optimum solution to a… [Read More]
FF examples of optimal blur management
This is a continuation of a series of posts about blur management for landscape photography. The series starts here. In a previous post, I showed you the results of using a blur management optimizer that I wrote on a scene using the Fuji GFX 50R. This post uses different scenes, the Nikon Z7 body, and… [Read More]
