Dear supporter,

I would like to make day/night photo with this app, had 13pro license.

I took the day and night photographs using the same tripod, without moving the camera position.

The day and night images for each angle match almost exactly.


The shooting covered approximately a 150-degree field of view and was stitched using about six images.

My main objective in using this app is to create a panorama in which the day and night images align precisely.

However, even when applying the provided templates, the resulting day and night photos do not match or align as expected. This makes it difficult to achieve a consistent panorama where both scenes correspond accurately.

To explain the issue more simply, the problem occurs because the stitched results for the day photos and the night photos are not the same.

When I stitch the day images and stitch the night images separately, the final panoramas do not align with each other. Even when I merge the two results and run the Auto-Align feature in Photoshop, the layers do not align correctly.

However, when comparing individual day and night photos one by one, each corresponding pair is almost perfectly aligned.

My goal in using this app is to create a consistent panorama where the day and night versions match accurately.

I would appreciate any advice or solution you can provide to achieve this.
Thank you.

I would appreciate your guidance on how this issue can be resolved.



Thank you for your support.

Hi Cina! I am not PTGui support staff, but I am a night photographer, a professional educator and LOVE PTGui. I use it all the time and teach it often. (This is not an advertisement; a complete answer is below.)

Here is a simplified description of what I discovered after struggling with the process for years:

1) Load ALL your images (Day and night) into the same PTGui Pro project.
2) Align all images - use the control points well. Make control points between day panels and night panels, too. 
3) Turn off visibility of all night images, export the TIFF with a unique suffix in the filename (i.e. "..._night" or ",,,_sky").
4) Turn on visibility of all night images and turn off visibility of all day images.
5) Export the other TIFF with a unique suffix in the filename (i.e. "..._day" or "...landscape").
5) Mask and blend in Photoshop - it should be either perfect or very, very close if your capture process was consistent. 

My business partner Tim Cooper and I made this free webinar that demonstrates the process in detail:

Best of luck!
