Need some input for a huge stitched landscape

Below is a sample of the lower third of the Goosenecks. The river twist back and forth through the canyons. My shots are composed of 42 images shot vertically. When trying to stitch them together in Photoshop I'm guessing the curvy lines, fall away lines of the canyon walls, and the very content of the image is completely a wreck when stitched together. I then tried just stitching the bottom layer using perspective, which usually works best for single line pano's. However, auto did the best stitching it together but created this terrible curve. Any suggestions? The canyon walls continue up and the walls continue to fall away.

If you've done something like this I would appreciate your input.

We had the wide lenses, but were trying to minimize warpage. However, it may not have worked as we hoped.
Don is right. When shooting that wide of a panorama you need to leave plenty of room for cropping.

You also said that this is the bottom row. How many rows did you shoot, and what does it look like with all the rows put together?

I have had better luck stitching with Hugin, when I shoot panos with fisheye lenses. I know your image has nothing to do with FE, but there is the curvature issue, which might be better understood by Hugin.

It is free sibling of Panotools, the de facto panorama stitcher. The user interface is convoluted, but a lot of step by step how-tos are available. It might be worth it to try.

Three rows shot vertically with 1/3 overlap. As for what it looked like... it went all kinds of wonky. The curving lines and fall away canyon walls confused it and it even put pieces where they don't go.

Willing to try it. There is so much complexity int he photo with the repeating curing lines that Photoshop just gets confused.

The curve may be due to the projection chosen. See if you can change the projection.

I use Microsoft ICE (before that I used Hugin, but that took too long and at times refused to stitch properly). It does an excellent job most of the time. You can choose the type of projection if the default is not to your liking. The best option in ICE is the "Autocomplete" - if you have sky at top or a lot of grass at the bottom, you can omit taking shots of them. The software does a fairly good job of filling the missing parts.

If you can send the images (downsized to say 1K on long side), I can try various options and revert back to you.

When you merged did you try the cylindrical aspect choice in PS? I sometimes use that with panos done with my wide lens and it often works.

The other thing you could try, a total pain, is to correct the wide angle distortion of each shot in PS before merging (it's a lot of work)
