Possible Bug ?

[Markos Georgiou]

Hello everyone,

I’m experiencing an issue with PTGui 13.3 Pro that’s quite hard to describe in words, so I’ve uploaded a short video demonstrating the problem. You can view it here:

Has anyone encountered something similar or might know what’s causing it? Any help would be greatly appreciated.

Thanks in advance!

Hi Markos,

It looks as if the metadata of your images is faulty. The exposure times
in the metadata do not seem to reflect the actual exposure. PTGui uses
the metadata to assemble HDR: it assumes that an image taken at (for
example) 1/40 second is twice as bright as the other image taken at 1/80
second.

If the metadata doesn't match the reality, those weird HDR artifacts
will occur.

I don't know why this would be the case but I can take a look at your
images if you make them available for download.

Kind regards,

Hello Joost thanks for your promt reply ive updated the google drive witht the images

Hi Markos,

I don't see any issues here. Your files are fine (my previous diagnosis
was not correct). After running Align Images the panorama looks fine, I
don't see the colored artifacts.

Have you ever changed PTGui's default settings? If so, could you do File
- Reset Default Project Settings and then try again from scratch?

If that's not the case, could you post your project file (after running
Align Images), so I can see what's happening?

Kind regards,

Markos,  If you have used a project file from an excellent stitch as a template,  you should then get decent stitches by simply applying the template and going straight to Create Panorama.  No control points are needed, nor optimization, of course.  The images cannot fail to stitch.  But some minor stitching errors due to parallax may be unavoidable when shooting indoors.  Your sample project files do contain control points poorly distributed and the featureless walls can be problematical, which may be the cause of distorted results.

So what is my solution ? 

[John Houghton]

Markos, If you have some images that "fail to stitch all together", by all means supply them and I'll try to identify what that particular problem might be.

[Markos Georgiou]

they are in the the ggoogle drive above ive been having alot of issues with pt GUI recently mainly with the X5s 

[John Houghton]

Markos, the Google Drive folder above has no camera image files.  Only project files and stitched results.

Markos,  Using the 4 files IMG_20251101_145056_00_272 thru' 275  I prepared a template that should work for similar HDR sets of 4 images.  Just load into PTGui the set of 4 dng images and then:

1.  Apply the attached template file using File -> Apply template. 

2.  Optionally level the panorama by creating a few vertical line control points on vertical features and then go to the Edit menu in the Panorama Editor window to run the Level Panorama option. (If you don't know how to use vertical line control points, miss this stage out).

3. You may want to visit the  Exposure/HDR tab to run Automatic exposure and colour adjustments and Tone map settings to obtain the appearance to your liking.

4. Go to the Create Panorama tab to generate the output panorama image.

If you don't like the result from the HDR processing, you can always enable blend planes on the Create Panorama tab and output 4 blend planes for merging in an alternative HDR application, such as SNS-HDR Lite.

Let us know how you get on.
