　Conserve original path of picture　　 Betamax　　 2026年1月20日(火) 18：03 　　 　Mail
[Edit]
Hello,
I use StereoPhoto Maker via Wine on Linux.

Here's how I create a 3D image:
I select two images from the Digikam interface.
I drag and drop them into StereoPhoto Maker and apply the necessary settings.

To save the image, I press Alt+S.
So, a dialog box opens, but it never saves to the original image folder. This is very frustrating.

Is it possible to make mpomaker keep the original image path and save new images in the same folder?

Depending on the size of the display on which the anaglyphs will be viewed, it is sometimes necessary to bring the left and right images closer together or farther apart, because objects at the horizon cannot have too large a disparity.

So, is it possible to create a tool to apply this modification without re-encoding the images (so that no detail is lost again)?

1- Open an .mpo file
2- Shift the images (move them farther apart or closer together horizontally)
3- Save the file without re-encoding the images

Maybe it would be enough to simply add a checkbox option in the save dialog:

"Copy images without re-encoding"

Hello, thank you for this fantastic tool.
It would be great if we could import .webp files into the StereoPhoto Maker window just for viewing.
Of course, for saving, a conversion to JPG would still be necessary since the MPO format only supports that format.

Using the WIC Susie Plug-in enables you to load WebP images.
Please refer to this page for configuration instructions.

Thanks, but it only works with "iftwebp12.zip" and for *.WebP.
*.AVIF and *.HEIF files don't open.

"ifwic22.zip" doesn't work at all.

Note that I'm using Debian/Wine (configured on XP).

What a cool, cool software! Using it since 2010 occasionally. Watching these old my 3D photos now, and they get me back into the reality of 2010. And I'm making a new photo for the future...

Hello, thank you for all the time and effort you have put into helping us 3D photo devotees.
I was very pleased to see in your latest release notes that you now offer the ability to edit and convert Lumpad's _lif.jpg files, this is great news for someone who has dealt with Leia's poor help desk, having to export files one at a time in a very time consuming clunky manner.
I have installed version 6.33 but cannot find LIF format anywhere mentioned in any of the menus. Please can you tell me how to work with them?
Thanks Martin

Please open them in the same way as side-by-side 3D images.

　Anaglyph Hald Generator - my contribution to stereo-3D ... and ... SPM feature request　　 Oleg Kosyakovsky　　 2025年4月14日(月) 0：17 　　 HP　Mail

Dear Mr. Masuji ,

I released the initial version of my free/open-source software "Anaglyph Hald Generator", and, if you find it relevant, I'd like to ask for support of its outcome in StereoPhotoMaker.
Specifically - for ability to apply pre-made color-lookup-tables. Of course it's up to you whether to provide it.
As the name hints, Anaglyph Hald Generator facilitates creating color-lookup-tables that optimize stereopairs for being viewed as full-color red-cyan anaglyphs. The tables adhere to "HALD" standard".

Application of these CLUTs aimed at reducing retinal-rivalry by replacing problematic colors by others that still somehow resemble them.

What could be considered the downside: requirements for viewing conditions (glasses, illumination, etc.) are stricter for anaglyph processed with Anahald's CLUTs than with half-color or Dubois anaglyph.

What should be considered the downside: not always retinal-rivalry is fully eliminated. Instead, it's a matter of trade-off between eye-comfort and color-accuracy. By the way, the same applies to the two additional undocumented methods in StereoPhotoMaker - Suto and SPM.

According to my experience with the testbase of ~350 stereopairs and 6 sample LUT-s, most of the images could be improved in comparison to half-color or Dubois form. The Suto anaglyph behaves similar to the most conservative (minimal correction) out of my 6 sample LUTs; it shows pure red-s slightly better, but at the cost of preserving retinal-rivalry in more cases.

I have used Anaglyph Hald LUTs for color processing some files before red/cyan Anaglyph conversion and can really recommend it. The final Anaglyph image has color close to the original (much more so than a Dubois Anaglyph) and little ghosting, at a very acceptable level.
It works in particular great for skin tones, retaining a natural skin color.

At the moment Anaglyph Hald requires using ImageMagick command line from a terminal window, which might put off man potential users.

It would be great to have the option in SPM to apply the Anaglyph Hald LUTs, either pre-cooked generic LUTs as an option along with the profile currently supported (Dubois, half colors, etc...) or custom LUTs that could be imported from the SPM menu.

It's a pity that the author of StereoPhotoMaker doesn't monitor this forum; supporting lookup tables in StereoPhotoMaker would be ideal for outputs of Anaglyph HALD Generator.
But since that's how the things are, I had to go my way.

The latest version of Anaglyph HALD generator adds Python-powered GUI Viewer for pre-made LUTs. Some 10 minutes of setup effort, and then you can enjoy the simple user-friendly app.

Compatibility: so far only Windows.

See dualcam.net for downloads and instructions.

Hello StereoPhoto Maker team

I have 56 3D stereo color slides of my parents' wedding in 1952 (or perhaps 53). My maternal grandfather loved photography, so I expect that he decided to have 3D photos taken when they got married. The viewer works and the slides look beautiful.

It seems that each photograph consists of two 24 x 24 mm slides side by side in a single 4 x 1-5/8-inch cardboard or glass mount. The photos below illustrate them.

But I'm one of their 4 children, 5 grandchildren and other close relatives who would like to enjoy these photos. Therefore, I will get them digitized so that everyone can have a copy.

It would be especially cool if everyone who has the digitized 3D slides could view them in 3D.

I see that StereoPhoto Maker can do this, as it "functions as a versatile stereo image editor \ viewer and can automatically batch-align hundreds of images and mount them to the 'window'."

What instructions should I give to the people who I will hire to scan the slides?

Thanks
Arthur

Disclaimer: I'm a user from SPM point of view, not a part of the team)
Tell the operator the scans are aimed at being postprocessed and then viewed on a computer, E.g. they should not be "optimized" for paper printing. And you want the highest possible resolution - at least 5-6 megapixels of course.
Mentioning computer viewing is important, since the labs tend to view the scans as immediate inputs for their printing machines. This results in exaggerated contrast and excessive sharpening. You don't want all this before your stereo-postprocessing.

If you are not staying on have the old feel and looking just for the 3D experience, I would suggest, extract the SBS (Side-By-Side) image and this can be transformed to several 3D card formats (based on viewer you have) or presented by 3D available projector (like Optoma).

Me personally, I have 3D printed Holmes glasses or there is company in england producing 3D glasses, than you just need to create exact version of 3D card.

BTW: I have just finished my tool to convet SBS to 3D Card, as I have tried for a long time to contact author of the StereoPhotoMaker without any response. So as a photographer taking 3D images, I have created the whole pipeline from .mpo files to the 3D cards without touch in case of need.

　Depthmaker request　　 William　　 2025年6月20日(金) 19：19 　　 　Mail
[Edit]
I don't see a forum related so I try it here since it's somewhat related since you use stereophotomaker to view the output.

So here's the thing, I like your app 'depthmaker' but I find it a bit annoying that there is no option to save as PNG (or tif) because I like to avoid compression artifacts seeing that many pictures need to be fixed since the edges (leftsided edges in the left mage and rightsided edges in the right image) are not smooth and the JPEG artifacting makes it worse.
So it would be better if you could select PNG or TIF as output in a future version.

I do like that the JPG files are at least set to quality 90 I have to add, some software is really unpleasant and saves in quality 75 so I'm happy you have the wisdom to pick a better quality :)

　Saving TIFF file in 16 bits?　　 Vincent　　 2025年6月19日(木) 2：20 　　 　Mail
[Edit]
Dear developper,

as far as I could figure out, TIFF files saved in SPM (be it SBS or Anaglyph) are 8 bits only.
It would be useful to be able to output 16 bits file for retaining full color accuracy, for further processing.

Thanks for considering my request ;-)
