Hi Ray,
Absolutely OK to use my image, I would not shared it if that was not the case!
Just to make it clear. It is a composite of two images. Camera was horizontal according to dual spirit levels. The two images were shot using different amount of shift and merged in Lightroom using rectangular projection. "Upright" was applied to the image after stitch. The lens used was a Canon 24/3.5 TSE LII on a Canon 5D3.
Best regards
Erik
Hi Erik,
Yes. I understood it was a composite of 2 images. I do this sort of thing quite often, but not with a Tilt & Shift lens because I guess I'm not keen on the extra stuffing around in the field.
For wide-angle shots I use the Nikkor 14-24. If it's not wide enough, I'll take a couple of shots for stitching. However, more frequently nowadays, when I happen to have, say, my 24-120/F4 zoom attached to the camera, and I want a shot that is wider than 24mm, then instead of going to the trouble of changing lenses I'll just take a couple of shots at 24mm, and later 'Photomerge' them in Photoshop.
I understand you will be limited in Lightroom for such purposes. However, I find that stitching programs are so good nowadays, even in Photoshop, that it's very rarely that I have difficulty in not being able to get a realistic result, especially after applying to the stitched image the range of options in Free Transform, such as Distort, Warp and Content-Aware fill, when necessary.
In Photomerge there are a number of stitching options, such as Auto, Perspective, Cylindrical, Spherical etc. 'Reposition' is at the bottom of the list and I suspect it is often ignored, yet I find that Reposition often produces the best result with no requirement to apply any Distortion or Warp later.
The attached 4 images show the different results I get from 2 images stitched vertically, with camera hand-held, horizontally. I have not made any alterations to the results from the Photomerge process. I'm merely demonstrating here that one should try all the options if the first 'auto' option doesn't produce a realistic result.
In these examples, the Reposition option definitely produces the most accurate and realistic result which also requires virtually no further processing, apart from cropping or the application of Content-Aware fill, if preferred.
The top of the unusually-shaped rock in the Reposition stitch, matches very closely the upper shot before it was stitched. All the other stitches in these examples are abominable distortions that would need lots of 'distortion and warp' correction in Free Transform, before they would be acceptable.
