I just read about a fun app called XP4N simulating XPAN here!:

That does seem like fun Akira! And nice examples too

"Two 35mm frames side by side" -- owners of a Nikkor PC 35mm f/2.8 or f/3.5 lenses can get the "XPan feeling" for free. Just shoot two separate frames with the lens shifted to either side, then join in post-processing. The frames should fit almost perfectly if the camera is kept still. Come to think of it, I do own such lenses, thus can savew not just $0.99 on the app, but the cost of an iPhone as well A project for the weekend.

Thank you, Hans!  I like its simplistic UI as well which enhances the joy of use.

Birna, I'm "owner of iPhone14" and thus can save the cost of PC 35/2.8 which is far more than 0.99 USD!

We sit on opposite sides of the fence If opportunity avails, I'm going to test the concept of the 35PC.

The fence may be there but it is infinitely transparent, not something like the iron curtain.

This has been an interesting discussion, tho I admit to not being a purist about how a panorama is created or defined.
After reading Birna's I remembered that I have a PC-35mm f/2.8. I've used other lenses for stitched panos to chronicle the progress, and decided to try the PC. Here are a horizontal and vertical pair that I used the maximum shift and rotated the lens 180° between shots. There is a pretty large overlap of about 20%, but less distortion than a normal stitch. A little blending of the overlap in PS tidied up the few parallax issues. The resulting stitch has almost the same angle of view as my 20/3.5Ai. Sadly, not the most dramatic subject.

Although this thread is, just as the title says, dedicated to the non-stitched pano, it is not to be purist or to condescend the digital stitching.  It is rather the rule or the restriction of a fun game.

I initially supported Hans for starting this thread because it offers a challenge that is different from creating the stitching pano.

[Birna Rørslett]

Use of the PC lenses still requires a perfectly stationary camera. Thus this approach is in an intermediate position between a stationary camera and single-frame captures in a panoramic view, and a rotating/moving camera taking several frames for later stitching.

Proof of concept. I ought to remember the PC-Nikkor 35mm f/2.8 never was a great IR champion, so should have pressed the older PC-Nikkor 35mm f/3.5 into service instead I set the aperture to f/8 to reduce the annoying IR hot spot. The 35PC was shifted all the way, which leads to some vignetting in the extreme corners of the frame.

Two frames on Nikon Z5 using the B+W 093 IR filter. Frames run through PTGui afterwards. Next time I'll use the 35mm f/3.5 lens instead, and avoid the extreme shifts.

The old PC-Nikkor 35mm f/3.5, as expected, performed much better in IR. It is less sharp than the newer f/2.8 and image contrast is more moderate as well. However, the performance still suffices to make acceptable mages (?)

Same setup as with the 35/2.8 PC. Apparently, I save myself the trouble of getting the iPhone to get the XPanN app. Or regret that I sold my XPan a few years ago.
