Photomerge Progress

After I created some panoramas on Mac something gone wrong. I try to creat new one but the progress stops at 33,33%. I tried to work on external disk and scratch disk too. The issue is the same. I dont need to purge the cache in I didn`t find temporary files created by Ps. Is there a problem with the memory?

Correct answer D Fosse

The progress already crached at the stiching files. Look at the file I have attached. On the anchor file image you can see another image and I couldn`t handle it. ACR is the best, but thanks for advice.


So, in other words, it fails at Auto Align. That's not crashing, but for some reason it can't align the frames.

 

Is there parallax shift or lens distortion? Sufficient solid overlap? If it fails on this set but not others, that's the natural place to start troubleshooting.

 

I'm not assuming anything here, but I can't see your originals.

Please provide a few details so we can help you. 

1.) How many files are in the panorama that you are putting together in PS? 

2.) What size is each file?

3.) How much scratch disk space do you have available?

I use macOS Monterey on iMac released from (mid) 2017. Ps is 23.2.0 release.

First of all I'd try with other "safer" sets of images, to find out if it's just this particular set. If it fails consistently, we're probably talking about a Photoshop bug. But in the meantime:

 

Have you corrected lens distortion in ACR prior to the merge? 16 mm is fairly wide angle (even with a small sensor), so there will certainly be some distortion, particularly with a zoom lens.

 

Also be careful to avoid parallax error (shifting the camera sideways). These two together can easily throw the algorithm off. There's no magic here, and Photoshop doesn't "know" what to merge. It just looks for identical patterns.

 

These are just two of the most common factors that cause auto align to fail. The third is changing waves/drifting clouds/trees moving in the wind etc - but that doesn't seem to apply here.


The raw photo segments which I was taken with the same camera and lens settings first time I edited in Lr and exported in JPG. After that action I stiched in Ps. Some panos are done but others doesnt.

 

When I tried to remake the panos (edited raw photos and stitched to panorama) in ACR all of panos are succeeded.

 

Yes I did, I corrected lens distortion in ACR prior to the merge, and before in Lr too. The photo segments had minimal camera shift horizontal or vertical. Maybe I moved away little more the stativ, but I corrected in Lr and ACR too.
