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

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 ;-)

　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

[Edit]

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.

[Edit]

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.

このアプリケーションは非常に優れていると思いますので、StereoPhotoMaker に関するサポートを提供したいと思います。

GPS情報の保存につきまして

お世話になっております。
GoProの360°写真（jpg）にGPSが記録されています。
こちらのアプリで編集し保存するとGPS情報が失われます。
GPS情報を残して保存するのは出来ないでしょうか。
仕様上、出来ないという認識でよろしいでしょうか。

保存時のオプションで、
「縮小画像を埋め込む（高速プレビュー用)」→「元画像にExif情報があれば、そのままコピーする」
もしくは、
「Exiftool.exeを使用して、元画像にExif情報があれば、コピーする」（別途、設定でExiftoolのパスの設定が必要)
でGPS情報もコピーされませんか？

むっちゃん様

返信ありがとうございます。

＞「縮小画像を埋め込む（高速プレビュー用)」→「元画像にExif情報があれば、そのままコピーする」
こちらは試していましたがダメでした。
GoPro以外のファイルで試すと上手くいくのでGoProのjpgファイルの問題でしょうか。
ファイル情報でも情報が表示されません。
しかしWindowsのエクスプローラーでプロパティを表示させるとGPSデータは見れます。

＞「Exiftool.exeを使用して、元画像にExif情報があれば、コピーする」（別途、設定でExiftoolのパスの設定が必要)
こちらを試そうとしましたが（ダウロードしパス設定）以下の様な「Exiftoolを使用して、元画像にExif情報があればコピーする」の項目が出ませんでした。

ExiftoolのZIPファイルを解凍すると「exiftool(-k).exe」というファイルがあると思います。このファイルを「exiftool.exe」にリネームして、設定でExiftoolのパスの設定してください。

GoProはもっていませんので、わかりません。別途メールで送っていただければ、確認してみます。

こちらと同じ画面が出ないと思ったら「保存」ではなく「一括変換」でした。失礼しました。
この方法でもExif情報は保存されませんでした。しかしGoPro以外のjpgファイルだと問題なく出来ます。

教えていただいたexiftool.exeをコマンドプロンプトからExif情報のコピーが出来ました。
一応出来たので良かったです。

ありがとうございました。
お手数をおかけしました。

SPM now launches!

Evidently the Flag was removed after multiple attempts to add file name after the command.

4. Enter sudo xattr -r -d com.apple.quarantine followed by a space

Initially I was entering a Return after Step 4 above.

I then tried to Drag and drop from finder to the Terminal before a return when the Terminal was in the Stack as specified below. I didn't think it executed but perhaps it did.

5. Drag and drop the SPM app into Terminal and hit return (you may need to enter your computer password)

You may want to combine Steps 4 and 5 or otherwise clarify the following Steps:

4. Enter sudo xattr -r -d com.apple.quarantine followed by a space
5. Drag and drop the SPM app into Terminal and hit return (you may need to enter your computer password)

Such as

4. Enter sudo xattr -r -d com.apple.quarantine followed by a space then Drag and drop the SPM app into Terminal and hit return (you may need to enter your computer password)

or

4. Enter sudo xattr -r -d com.apple.quarantine followed by a space (don't enter Return)
5. Drag and drop the SPM app into Terminal and hit return (you may need to enter your computer password). Instead of drag and drop followed by Return you may enter the PATH and FILE names such as in the following example: /Macintosh HD/Applications/SPM_Mac.app then enter Return.

SPM now launches!

Is there a way to use the Create 3D image from 2D+depthmap(360 version) in a batch mode?

I would like to create 3D 360 videos frame-by-frame this way.
