Stacking. Focus or move
Aug 24, 2017 18:56:34 #
Getting a series of shots to create a focus-stacked image can be done either by keeping the camera at a fixed distance from the subject and adjusting the focusing, or by keeping a fixed focus and moving the camera toward the subject. I have looked for a site that analyses the difference between these two methods, especially as it relates to lighting and image parallax. If any readers are familiar with such a site, I would appreciate a link. Thanks.

I'm looking forward to some of our accomplished macro photographers to reply to this one. I've had the same question for quite some time, but have been busy photographing other subjects.

Go to this link: http://zerenesystems.com/cms/stacker/docs/tutorials/tutorialsindex There is a lot of information in these tutorials. I've stacked using both Helicon and Zerene-- and for my money, Zerene does by far the best job of resizing and aligning images. In my experience, focusing using the lens is workable for landscapes and for macros up to 1:1. At greater magnifications, the very minute adjustments due to the very thin DOF, require moving the camera and lens using a focusing rail

Allen, would moving the camera using the focusing raiils work for both landscapes and macros up to 1:1 also? Or is that not the optimum way to go?

This link has a chart about which system is best for each type of project. It considers using a rail on landscapes as 'impossible'. http://zerenesystems.com/cms/stacker/docs/troubleshooting/ringversusrail

Thanks, LRF. Actually, a lot of my landscape photos are done with a view camera. So, for me the Scheinpflug principle works quite well. http://www.uglyhedgehog.com/t-458709-1.htmlMoving the camera for landscapes isn't practical. The distance required is too great.

In looking at your equipment list, I think you're looking for a more technical link than those provided. You might do a key word search at http://www.photomacrography.net/forum/ You might also try "Telecentric lens". Hope this helps.

Great site.

Agree about Zerene, I've been using it for many years now. Excellent program and great information resource from Rik Littlefield who also administers the photo-macrography site.
BTW Tele-centric lenses is a topic of great interest to many folks over on the photo-macrography site, myself included.
