Title: Problems stitching with CS3 photomerge
Post by: marcmccalmont on August 10, 2007, 11:45:48 am
When stitching with CS3 photomerge I am less than 50% succesfull. Too often the files are stitched and then when blending starts they just disappear! There is no relation to how many files are being stitched. It sometimes fails with just 2 frames. Has anybody else experianced this? Any solutions?
Thanks
Marc

I've been using it a lot and haven't encountered any problems, and I've been merging huge 39 MP files, with final output file sizes approaching a gigabyte in size. The only thing I can think is that you are running out of memory and the job is terminating as a result. If you have any other apps open at the time, try closing them before starting the blend. If you are having out-of-memory problems, this might help.

I tried that and selected both harddrives as scratch disks,  HP  dv9000, 2 gig of ram 1.4 allocated to photoshop.

I know it sounds stupid, but try reducing your ram allocation in CS to 60%.

reduced it to 50% and did a repair to CS3 still no luck. Next step I'll call Adobe but I was hoping for a quick solution
Thanks

FWIW, I've been having CS3 stitching problems, too.  Stitch failures, stitching with no blending, inability to save stitched result due to "not enough memory" notifications from CS3.  

Dual-core with 3GB.  If I reduce the memory load by degrading the source images (JPG) it sometimes solves the problems.  Killing all other processes seems to help, too.

Mort54, what are your system specs?

I'm running on a Mac Pro with 4 GB of RAM, 2.15 GB of which is allocated to CS3.

What are your cache levels set to?  (Try using 6.)

Adobe was good about responding via there technical support web site. They gave me several items to help debug the problem and I very quickly found the issue was in preferences. If units and rulers is set to percentage (my normal preference) not inches Photomerge does not work???? Let’s hope they will fix the bug quickly. At least I have a work around.
Marc

Thanks for you ideas and help!

I am encountering the same problem (disappearing merged file with no error message) by my U&M is set to inches??????

Oddly I did to this morning that worked fine, same size files.

Any other thoughts???

Reducing memory allocation results in the error message "photoshop has encountered...and needs to close etc.

It worked this time, but directly from the raw files, merge set to Auto and 60% Memory allocation? I'm not sure what of this did the trick, but I am happy as I am under the gun to deliver these to a client

I used PS to stitch one today set the preferences to inches and it worked fine. I can reliably recreate the problem by selecting percentage.

I had to stitch 2 halves, my telescope will fill the 5D with 3/4 of a full moon so I had to shoot the top and then the bottom. ISO1600, fighting the wind and vibrations, not so good but at least I recorded the moment.

Odd, mine was set to inches when I was having the problem. There must be another factor with my setup?

Adobes solution was to set up another user account and migrate all of your programs to it. Too much work for me so when I use Photomerge (I usually use PTGui) I'll switch to inches. Adobe says it is not a bug in their software but a windows user account issue.
