I'm back at it again, testing my new Cambo RS with a 35mm lens and P45+. I'm testing several things all of them dealing with multiple imaging stitching. What I'm attempting to see is the IQ of single row multiple panoramas as well as multiple row images. So far I've kept the shifts at 10mm left and right as well as 10mm rise or fall.
Prior to the RS I was using RRS pano gear to accomplish the same end result. I used this kit for single and multiple row/column imaging with what I thought at the time good results. I say "good" as anyone who has attempted to do panoramas knows they are very difficult to do (well). Every time I thought I had the tripod/camera level and had found the nodal point of the lens I had a lot of missing pixels which caused a cropping effect of the finished image. No so with the RS; while I'm not getting a perfectly framed image I am getting one that has less than .05% (estimated) that is thrown away.
Here's a couple examples (I normally use photomerge directly from the bridge that way I can keep the images in 16bit). The first image shows a completed 2 image stitch fresh out of PS4 while the second shows a 2x2 image (8707x7600) fresh out of CS4. The subject matter may not be the best however this is simply a learning experience for me for when I go out and do the "real thing". We're headed to the South Rim then over to Death Valley in mid December then off to Northern CA and the Redwoods and coastal shots in January. Neither trip is a place to still be learning the quarks of a new system.
The last image is a single image that I used to test taking a subject that was close in, in this case this was taken within 8' of the camera.
Here's 3 100% crops
There was little to no post processing involved in any of these images as I wasn't intending to use these as fine art samples nor did I intend to print them, their sole purpose was to guide me in the aspects of multiple image panorama and (at least for me) close subject imaging. I also needed to see if my original thought of selling my Mamiya 28mm lens would hold true.
Here's my conclusions based on this test. I will be able to produce panoramas of equal or better quality than before, and I can sell the 28 without any seller remorse.
Thanks letting me share and please be on the look out for my sale of the 28mm - I won't take it down this time.
