Itching for Stitching
« Reply #40 on: June 03, 2008, 07:39:14 am »

Hi Neil,

Looks like a roof-top image of Zurich :-)

I think the problem is the 3rd image ("3.jpg"). Looks to me like there is very little or no overlap for stitching between image 3 and 4.


I don't use CS3 for stitching I use PTGui. This shot might be rescued if you can use PTGui (or realviz/autopano) to manually place some anchor points between image 3 and 4. Assuming there is ofcourse some overlap...

Thanks guys.

I think you're right. I think the problem probably is the overlap between 3 & 4. You obviously really do need a fair chunk.
I shall re shoot it now & report back.

It's shot on an RZ with a 110 lens, so no wide angle.

(But I am thinking of trying one next week on a Cambo Wide! (35mm lens))

And yes andy, it's the view from my kitchen balcony in Zurich  

Thanks again.

It was the overlap - Thanks.

Re- shot with almost half of each image overlapping.

Hi Kirk, nice work on your site.

I only see a few images in your new arch. work that I'd be leery of stitching.  Mostly glass/steel with strong perspective:  Albuquerque Museum exterior, "Breathing Space 8", perhaps Fire Station 21 (depending on where the frames overlap), and Sandia MINI, although the angle of view doesn't seem too wide.

Have you compared the perspective between CS3 stitched shots and a single frame from a shift lens (matched for angle of view)?  It's been a while since I checked this, there was some reason I was turned off of PS stitching that I can't recall now...

Cheers

Sorry I never saw your post till today. Thanks for the kind words. Actually the site is almost two years out of date and I need to spend some time updating it. Generally I do stitching with segments from T/S lenses (24, 35 PC, 45, and 90) so perspective problems are not an issue. I use stitching to gain a wider perspective, build pixel size and do panoramas.
