I've been shooting bracketed JPG's and stitching works fine. From suggestions made in this forum, I've switched to RAW. Camera/lens is Lumix L10 and Zuiko 8mm fisheye. Adobe DNG converter used to convert RAW to DNG. Import of the 6 DNG images works fine but the next step of stitching is where I run into problems. Panoweaver is hanging around 40% of the way through. The progress bar dissapears and nothing happens.  If I click the 'pre-stitch' or 'stitch' again, the progress bar and window will momentarily appear. I've increased Windows paging to initial 2.3gb and max 4gb. I've have 1GB of RAM, Centrino, XP. The problem has been sent to support and they restated the steps in the manual which are quite straightforward and what I was already doing. It may be that there is something unique to my setup here but I'm not at all sure what to try next. 

Any suggestions, pc changes, workarounds that will allow me to continue shooting RAW? Thanks, Don

Don,

I would first suggest you stitch a set of jpgs to make sure the program will at least do this correctly on your PC.

I'm not sure why you are converting your images from native RAW to DNG? Unless your camera outputs a file type no supported by Panoweaver?

Why not process the RAW files using ACR and save as .tif and then stitch?

Until I have more of an idea what you are actually doing and why it is hard to say. Can you supply a link to a set of images for me to test for you?

Regards, Smooth

Hi Smooth,

I was shooting bracketed jpgs and they were stitching perfectly. I'm just in the process of switching to raw. 

The Lumix format is .raw but Panoweaver imports .nef .crw and .dng. I only tried Adobe dng because their converter has a nice batch process that converts all files in a directory, preserves the original and creates dng. I hope I understand this all correctly.

Support has since come up with another suggestion which is to adjust the panoramic image size to something small, say 200*100. I tried this and the stitching process worked correctly, producing the results I expected. I take this to prove that the shooting, import, format conversion etc, are all working correctly. The problem of course is the size of the panorama. I usually set it to Web Broadband, 4000*2000. This is so that quality is good on an Intranet where it'll be used fullscreen and in presentations. 200*100 is completely unuseable. I am guessing though that if the process works when the panorama is small but not when it's large, there may be a problem with pc resources?

Given that this PC is a few years old now and only 1GB, maybe the next step is to add another 1GB or find a 2GB pc to test on?

Thanks for the comments Smooth. Is there an address I could email the files to?

My Mrotator TCPs arrived today, another of your suggestion from somewhere in these forums and I'm looking forward to playing this weekend. We have snow on the mountains in Vancouver and I have the opportunity to take panoramas around skiing and mountain activities.

Hi Don,

OK, I get what you are doing now,

Yes, I would add more RAM for sure.

I will send you a Private Message with email details and how to get the large files to me.

Congratulations on the Agnos MrotatorTCPs purchase, once set up correctly it will be a pleasure to use and last you for years and years.

Regards, Smooth

We have an aging P4 with only 1 gb ram.   Stitch 4000 x 2000 just fine and at a medium speed 3 minutes process

We shoot 4 images Canon .cr2 raw converted to 8 bit tiff's.  8 bit tifs work in Panoweaver.

However,I do not think 16bit tif will work in Panoweaver

DNGs look suspisciously like the cause of the problem.

In PS, I saved that same set of images as TIFFs. With pano set to Web Broadband, 4000*2000, stitching worked perfectly, and on the same 1GB PC.

Thanks Smooth and Dave.

Regards, Don

Don,

Mate, new power supply fitted and all RAMmed up!

I need to ask the question: What panohead are you using?

The images sent to me are nowhere near the NPP position (not even close). If Panoweaver is hanging I'm not terribly surprised. I'm still to test the .dng files but I have successfully stitched the .tif's (well successful to the point I have a panorama image) but full of alignment errors.

Happy to help if you can provide more information.

Regards, Smooth

'Morning Smooth,

My new panohead arrived yesterday and those images where shot a week ago on a standard tripod. They were only taken for the purpose of proving out the raw process, which is now working for me using tif's. It's really not worth spending any time on them except maybe to prove out the dng hanging problem.

Thanks, Don

Another update. I've just added more memory to bring the pc up to 2GB. The stitching process with dng ran through to completion and according to task manager, used up to 590k. No wonder the extra GB was required. This gives me a couple of choices now and in the end I'll probably stick with the tif suggestion.

Regards, Don
