Broken: 2.77 22a2853
Worked: ???

Short description of error
When rendering in stereo 3D anaglyph, the left and right images are rendered half transparent into the view port as they should. However, when saving the image (F3) using multiview strereo 3d anaglyph modes, the saved image is much lighter than the rendered viewport image.

Exact steps for others to reproduce the error
Just render something with Stereo 3D Anaglyph and save it as such with Key F3 from the view Screen.

If I opensaved image in blender, I have no difference with render.
Did you open it in another app and observe the highest brightness there ?

It could be a difference of management of image color space.

It is exactly the same blender file as I used in v 2.76 and I used the MS Image Viewer in both cases.
The Problem only applies to Stereo 3D Anaglyph renders.

I can not reproduce the issue.

Please provide exact .blend file which demonstrates the issue and exact steps you did to reproduce the issue.

Hi,
first of all I have to correct one thing I posted earlier. After reinstalling version 2.76b, I found out that the problem is there too. So it didn’t work with 2.76b.

To give you a better idea what the problem is, I took a commented screen recording:

The files are also attached.
I hope that helps.

I can confirm the issue here, note that it affects any 'combined' saved picture, side-by-side is also much lighter e.g. than left and right saved separately…

@Sergey Sharybin (sergey) could it be some missing color management somewhere?
