Hi!

I have a two-row pano where both rows stitch very well (RMS 2.00-2.16) if I stitch them individually. However, if I stitch them both together the pano detection fails miserably and I get a warped and garbled mess (RMS 16) where clearly the left and right side images are all mixed up. To add to my confusion, the whole 20-image pano did render perfectly three or four times, and now it does not do so any longer.

What troubleshooting steps might I take in such a case?

Thanks!

If you cannot sort it out using the Control Point Editor (are you familiar with the CPE?) then shut down APG and start it again, and remake the pano.

The problem seems to be caused by the fact that I did a little lightening of the darkest shadows in Photomatix. I can get 19 of the 20 images to stitch with RMS 2.13, but the leftmost image in the lower row (containing mostly deep shadow with leafy bushes) throws APG for a loop. That's when it fails.

Have barely touched the CPE yet. I'll start reading about it now...

What steps might I take to either fix the 20-image detection so that this one image doesn't break it? Or, can I add an image to an already-detected pano?

Can you show a small version of the single panos and the bad stitch?

best, Klaus

For a variety of reasons there will always be panos where the ability to use the CPE effectively is essential.

I'm sure of that, and will definitely attack it... just hadn't done so yet.

It is best in such a case to try changing detection quality to High, if that fails to incorporate the missing image then select the option to force all images into the pano and then try using the CPE to link the image, if that fails then try moving the image into place manually, or by manually entreing Yaw, Pitch and Roll values, and then hard link it.

I set detection quality to high already (matter of fact, unless there's a reason why it might be a bad idea, I'll probably just leave it on high permanently). I'll try the other ideas you suggested later on tonight. Thanks.

I'm not sure whether restarting APG had something to do with it, but I did restart APG and the detection worked fine... so I just saved it, thanked it, and will quit worrying about it. Just has to work once.

Thanks for your help!
