Photoshop CS5 Photostitch

Hey,

I'm having very severe problems with Photostitch in Photoshop!
I'll try and explain what's happening.
So firstly, I'd take photos with everything set to a standard setting ( white balance, shutter speed etc. )
Then I'd run it in CS5.
It'd give me a fairly decent Panaroma.

But now,
I'd do the exact same thing, and I've checked to ensure that exposure of the photos are identical.
Then I'd run it through 'lens correction', just to ensure that everything is 'standardised'.
Then, comes Photostitch.

After several centuries, the panorama will emerge.
But, photoshop will do an ABSOLUTELY HORRIBLE job of stitching the image ( and my expectations aren't that high either and am willing to do a bit of manual adjustment ).
Furthermore, it will also 'correct' individual images, adjusting exposure and stuff, which makes the entire panorama look patchy with drastically different exposures ( thanks to photoshop correction. )
I've unticked any box which seems like it'd make photoshop do anything to the images and just stitch it only.

I'm really really upset that photoshop is so horrendous for panoramas all of a sudden and I don't know what I did wrong.

I didn't save any of the horrendous panoramas, but will run a set of images through the photostitch again and post the images I used and the end product if any of you require it for reference.

I can't figure out what I'm doing wrong...

Thanks for reading this lengthy post and please please please help!

I suspect that this is your problem, since you said that without it "It'd give me a fairly decent Panaroma."

Hey, I only started doing 'lens correction' after the photostitch started giving me junk just to ensure that my photos were dead perfect for stitching and it couldn't have been the photos' problems

On some occasions "auto align" can be weird.
You could try a different setting, or you could try Hugin.

I find CS4 stitch works well with good input material. The keys seem to be:
- Manual everything - exposure and WB.
- Shoot portrait even for wide landscape shots, it gives you more room to crop.
- Use a tripod if possible, or level it in RAW.
- Any adjustments need to be applied to every image equally.

This is a symptom of inadequate RAM in your system for your version of Photoshop and/or your OS
Frank's right...avoid the lens correction as well as any cropping/leveling before the merge process. As Tim said...shooting manual, wide and syncing your pre-merge settings is necessary for a successful outcome. Also, avoid the adjustment brush.

But something has changed. To eliminate the probability of a problem with Photostitch, take a set with a tripod & be sure to overlap the edges about 30% & see if that works. If it does, then the problem is with something that you're doing before assembly.

I've shot a 360-degree pano hand held before & had no problems assembling them, so you should be able to do that, too.

Thanks all for you replies!

Hmm... Okay, I'll give hugin a shot tonight.

1. Done
2. But isn't that just for a larger image size?
3. Used a tripod already
4. No adjustments at all.
And the problem is still there!

But according to the website, my system requirements are all above the stated...?

Well you see, that's exactly what I did as part of my troubleshooting before I decided to ask for help here....

If possible, post a few of the originals and your result here.

Did you use a bubble level when you took the shots?

Was the scene you shot rapidly changing?

Have you tried it without the lens correction step yet?

Okay, I'll run it through cs5 again and post the results soon...

Nope. But it doesn't seem that necessary, is it? And furthermore, last time when the panoramas consistently worked, I sometimes took the shots handheld and sometimes on tripod...

Was the scene you shot rapidly changing?
definitely not
Have you tried it without the lens correction step yet?
Yeap. The lens correction is only because the panoramas were awry and I decided to run it through lens correction just in case

As above...

No, it's because you lose the top and bottom off a lot of the image. But it won't solve your problem.

Then, if all else fails, maybe you should uninstall & reinstall the app.

Is your series low contrast? e.g. a fog bank?

Most definitely not
Maybe I should just install again...
