How do you cope with Reds in colour Anaglyphs, please?

In colour Anaglyphs, I get good enough Blues and Greens by saturating them but don't know how to deal with Reds.

Any suggestions, please?

So far have stuck with B&W Anaglyphs which are fine. X-Eye and Side x Side don't allow zooming in for detail.

Re: How do you cope with Reds in colour Anaglyphs, please?

What are you using to create your Anaglyphs?

Stereomaker has a Dubois Anaglyph selection that mutes reds so other color stand out. I sometime post process through Paintshop Pro and reduce red in both left and right images (or boost other colors, especially yellow) from an MPO file and save each as a jpg and create an anaglyph from them in Stereomaker. If you seriously want the best Anaglyphs that retain the most color, then create yellow/blue Anaglyphs, however, you will need to get yellow/blue glasses of course. They can be purchased online.

I suppose that you wants to see red object as "be red" inside anaglyphs.
To see full colors anagliphs, the best solution is ColorCode 3-D or something similar.

Another solution is to use some custom 3D glasses with Red filter and a custom Blue filter. In this case, the anaglyphs must be tuned toward warm colors.

Photoshop CS6. Switching off the Red channel in the RH image and Green+Cyan in the LH.

From the above, I see you are dodging the plain Reds by reducing Red and shifting away. As long as I know that, I can follow. I have been playing with monochrome Anaglyphs for some months and am entirely happy with that but would now like to add colour but only if I can find a satisfactory way. My subjects are mostly architectural ruins and the limestone buildings are almost monochrome anyway. So there's little loss there.

I read about different colour pairs in spectacles but Red/Cyan are what my viewers have, and seem almost universally popular on Anaglyph web-sites. I'd like to stay with them for the larger audience.

I accept your technique and will pursue it. I have read and tried using methods involving CMYK and adjusting in Colour Channels but t gets too complex for me. See:-

http://nzphoto.tripod.com/sterea/anaglyph_make.html#RCchannels

I just enjoy the simple monochrome process in CS6 and the more complex colour techniques, when it comes to REDs, dampen my enthusiasm.

Attached are one normal monochrome plus one colour attempt (falling down on Reds).

Thank you for your advice.

Have found a supplier of ColorCode 3D Glasses in UK so will order them and have a play and see how much better they are for the purpose.

I thought I would only play with Anaglyphs for a couple of weeks but have become fascinated with them. When out with the camera, I only think in 3D terms now. At least it distinguished from SmartPhone pictures (at least for now). My pictures use the Cha-Cha method and i really like the mental input to them - like old-time photography! i started in 1948 and have recently had a couple of years using 120 film, 1950s, folding cameras for nostalgic fun. However, for the Anaglyphs, I use a full frame digital with 28-135mm zoom. Discovered that using the lens stabiliser produced 'pools' of distortion between my two stereo shots so only use it with stabilising off.

Another solution is to use some custom 3D glasses with Red filter and a custom Blue filter. In this case, the anaglyphs must be tuned toward warm colors.

Thanks for your reply. I am interested to see the effects of ColorCode 3D specs. If it is a big improvement, might have to make the change, dish out CC 3D specs and rework my previous images!

Re: How do you cope with Reds in colour Anaglyphs, please?

Tony, take a look at these Albums done several years ago. Phereo works better on Chrome, but can be slow to respond. These were all taken with either the Panasonic 3D1 pocket camera or the Fuji W3, and processed through Stereomaker. I think you will find the Anaglyphs watchable without weird eye-glare. The colors end up to push greens and yellows, so many of the images look like B/W with yellow and green added.

Regarding color reproduction, ColorCode 3D are the best, the drawback is that glasses (filters) are darker than other 3D glasses, and anaglyphs need a proper "recipe" to be prepared. They are not just "Yellow-Blue" anaglyphs.

For clasic Red-Cyan anaglyphs to be viewed on monitor screens, Red-Blue Green filters are the best to reproduce ~red colors. But Red-blue Green glasses can be hard to find.
Some kind of plastic Red-Blue glasses are also very good, but may be possible to need to try several different products to find the good ones.
..............................
If you are realy interested in good 3D images and videos, forget about anaglyphs and invest in a good VR device. This is another world.

What?  Open your anaglyph in SPM and hit F2 as required...

Worked fine as advertised, thank you. However, I can't expect my '3D virgin' friends to have SPM installed on their PCs/Phones.

Happy to know it can be done though.

What software do you use for creating ColorCode 3Ds? I have used just the Yellow-Blue output of '3DJournal_v32' which IS only a direct equivalent of Red-Cyan treatment of normal Anaglyphs. The results are not bad but anything to fine tune them would be welcome.

It is the addition of the 'proper recipe' that you refer to that I am looking for. ColorCode 3D Editor seems to be available only with bulk purchase of their specs. I have just a few paper versions which don't include proper creation software.

Any suggestions?

Re: How do you cope with Reds in colour Anaglyphs, please?

You can use stereomaker from www.stereomaker.com. You can also tweak the color in left and/or right to get the best color from glasses. ColorCode is actually blue and amber(ochre), which they have tweaked slightly and patented for "full-color" 3D, though it is clearly not, but at least you will get the sense that it is. The glasses are very dark, and they use a lighter shade of blue/yellow on the image. Don't be fooled by their patent, it's still basically blue and yellow--the amber/ochre allows more colors through. They used it on photo displays, advertising, and TV shows, but never really caught on. From a distance, you will think you are seeing a normal color image, but when you put the glasses on you see it in 3D. They used to do this by adding a little blue and yellow that kind of disappears from about 5-10' back. The glasses are dark, though, and you need a bright light on the image. Same with the TV, you need a bright image. You can do the same by creating 3D blue/yellow stills--anaglyph jpgs, and save them to a memory stick and plug into your TV and show them that way. I have done that with red/blue. I have some yellow/blue glasses and will experiment with them this weekend and see if I can duplicate the "full color" image they talk about. It's just a matter of getting the color right.

Amazon had the color-code glasses: https://www.amazon.com/ColorCode-TM-3D-Glasses-Pairs/dp/B001ROY6GW/

You can see that the amber side is very dark.

Great!.

You can also zoom in on SBS as well using the same procedure.  SPM can be had on android, App called 3DStereoid.

I got some glasses OK but could not open 'www.stereomaker.com'. Got a '404 Not Found' reply. I found Stereomaker v2.5.1 to download but it was from August 2000 so perhaps they are no more? The download turned out to be an .hqx file which IIRC is for Mac OS, not Windows (mine).

I find that viewing ColorCode 3D stills is best in a darkened room and the colour is quite acceptable in the Red and human skin range.

Thanks for all your advice.

Please note that this will install as a desktop app only, so you have to unzip it and drag it to your desktop. The first time you run it, it will poke your registry etc., and Windows 10 will probably refuse to run it. Click on the more info if that warning comes up and click on Run Anyway. Windows will run it as a compatibility app from your desktop. Believe me, it is perfectly okay with no harm done. I am running the 64bit version under Windows 10 and it works flawlessly. I have also run the other versions and they run fine as well. Most people will probably not figure out how to run it as they are used to going through an install for all their apps. This app does not need to be uninstalled if you don't want to use it.  You just run it, then click on Help. Click on Clear Registry, then simply delete the app from you desktop.

Right, I did get StereoPhotoMaker v6.03 before. You mentioned 'www.stereomaker.com' and there was software called 'Stereomaker' but I couldn't find a download for it.

In SPM I input the DeBois matrix for the Optimized Anaglyph setting for Amber/Blue (Yellow/Blue) ColorCode3-D images and that seems to be excellent.

Oddly, while creating from Left/Right jpg pairs, I can't find out how to get 'UNDO' to work. It is just greyed out. Closing one image without exiting SPM is also a puzzle to me. Any clues please?

3 results:-

Homebrew using CS6 for R/C Anaglyph:

SPM using Red/Cyan DuBois for Anaglyph:

SPM using Yellow/Blue (Amber/Blue) DuBois matrix for ColorCode3D:

Quite a lot of progress thanks to kind responses to this thread.

Re: More info on Stereomaker...

The difference between Red-Cyan and ColorCode is obvious in images rich in warm colors. The ColorCode technique offers a wealth of color shades that are neutralized in Red-Cyan Mode.
I make them of all kinds in Photoshop. I'm using SPM only for a fast check.
In general, SPM is very fast and gives good results (but not complex enough for commercial applications).
