Bitter, by “turn off” do you mean setting it to monitor color?
I generally select “no management”
I might need to revisit that in a different circumstance, but this is what we did in a pipeline I worked in that seemed to be correct. (Where I am now has an. . .interesting idea of linear color pipeline.)
I’m trying to get my head around what David said.
I understand the linear work-flow in Maya 2012
I got my image set up as EXR 32 bit my output set to linear in the color management tab
now, if I’m going to post work, Nuke for example
I need to make sure that I have the proper lot for the screen that I’ll view on.
what if the output is going directly to TV commercial.
DO i even bother rendering out EXR files?
recap my work-flow in 2012
[li]Select sRGB as your Default Input Profile. [/li][li]Select Linear sRGB as your Default Output Profile. [/li][li]Framebuffer, select RGBA (Float) 4x32 Bit[/li][li]File Format OpenEXR[/li][/ol]while working in Maya to view my linear
[li]Window > Settings/Preferences > Preferences, and under Rendering, select 32-bit floating-point (HDR) under Render view image format[/li][li]In the Render View window, select Display > Color Management.[/li][li]Select Linear sRGB as the Image Color Profile.[/li][li]Select sRGB as the Display Color Profile. [/li][/ol]at this point
A-If I want to go directly to TV (no post process)
Do I change back to output to be SRGB, now did i loose all my work?
B-if I go to Nuke, the images are “washed out” because they are in linear. we can use the cololorspace node to view them.“correct”
then write out as sRGB cause we r going to TV?
If you are going to do any post work then you are best with an EXR in linear colorspace.
Nuke also performs operations in linear colorspace just like a renderer does.
Then output to the desired colorspace from Nuke, not Maya. For TV it’s generally sRGB but for HD it can be rec. 709 which is similar, but a different gamma.
BTW, you can output to EXR RGBA 16 half instead of 32 and get nearly the same depth as before but a smaller file.
I edited my post to better describe the Q
thanks for looking
You can change the output to sRGB and not lose the internal rendering of linear color if you do this. That should be fine if you are rendering for beauty. Your output can be somewhat arbitrary if you aren’t doing post work as long as the rendering is in linear colorspace.
If you render to sRGB but rendered to EXR files that are floating point then you can use the colorspace in Nuke to “neutralize” that. It’s not recommended but would be better than nothing at all.
Seems you have a pretty good idea of how this works.
Thanks alot David!
I guess my problem was trying to view the rendered 8bit images in Fcheck. … and it cannot display linear.!
I need to look for another viewer
Any recommendations ?
but did not work for me, I think windows photo viewer was good
Here is my render and test file
TGA > still came out as sRGB >> it removed my light decay
Tiff 16 same
Tiff 32 was fine’
Viewing a single frame is easy enough in imf_disp that comes with Maya.
For motion try djview like DJX said, Framecycler, or Nuke (variation of Framecycler). Chaosgroup also has PDPlayer.
Ummm. Sorry for the confusion. I did a quick search and didn’t even check the link.
Matt is correct. I meant djv view.
Did it work for you guys with the images and file i shared?
on my side the Djv view will open both the 8 and 16bit as if its not linear.?
I think there is where I’m stuck at?
if i would to take out the images as 8 or 16 out of Maya and directly go to TV?
I think there is a slight misunderstanding of the workflow
Sorry if this was already answered in pervious pages > I didnt check.
I know both Davids did a lot of explanation in this thread
What you described was the LWF to be then taken to a comp application.
If you are taking out of Maya and thats it!
The settings should be sRGB > sRGB…
Here is the test filerender as RGB 4*8 and still holding the decay as you described it.
As for the imf_disp, if you open a 32bit file, you can change the gamma in the imf_disp window itself.
The 8bit images will be slightly darker, than the 32… but that would be expected
Now that 2012 is out, does anyone have anything to report about fixes to color management?
I am currently trying out the Color Management in 2012. Am I right, that we still need to use a gamma node for color swatches? Textures are working fine but then you choose a simple color you still need to gamma correct.
I’m pretty sure procedural textures still need gamma nodes as well.
Straight out of Maya 2012 help:
Color swatches are not color managed. To maintain a linear workflow, single color swatches in shaders, procedurals, utility nodes and lights should be converted to a linear color. A simple way to approximate this conversion is to attach a Gamma Correct node (Window > Rendering Editors > Hypershade > Maya > Utilities) to any Color attribute of a rendering node, then set the Value attribute of the Gamma node to the desired color and set all three Gamma values (RGB) to 0.455.
yes, simple colors and color nodes like ramps still need to be gamma corrected.
