CalibrateMacbeth

A Nuke tool to calibrate an image containing a Macbeth ColorChecker chart by calculating a ColorMatrix node that conforms it to a specified colorspace gamut. CalibrateMacbeth Screenshot

About

Calibrate an image containing a macbeth colorchecker chart to match the gamut of the given colorspace. Requires the numpy python module. Make sure it is importable in nuke. You can enable "use system python path" if you have it installed in a system directory (currently linux only).

Usage

  • Align cornerpin to match patches to macbeth chart
  • Set sample size to get a good sample on source macbeth chart.
  • Choose target colorspace.
  • Disable calibrate chromaticities only if you want to adjust exposure as well.
  • Click calculate
  • Evaluate results: Output in compare mode to get a better view.
  • Toggle bypass matrix to compare before/after.
  • Click Create MTX to create a new colormatrix node
  • Or click Set Selected to set an existing colormatrix node.

Information

Based on Marco Meyer's mmColorTarget tool. www.marcomeyer-vfx.de

Changes

  • Rebuild and simplify.
  • Add option for ColorChecker2014 in addition to ColorChecker2005.
  • calibrate to known gamuts only.
  • Add option to not change exposure when calculating calibration.
  • Created by Jed Smith - gist.github.com/jedypod

hi this looks awesome but how do i make numpy importable to nuke? cant find anything on the internet about this at all :( i dont know anything about python at all.

Hi Emartin8907
you need to copy the numpy directory into the directory Nuke11\pythonextensions\site-packages
I dont think it works if you copy from the python\lib\site-packages as numpy is compiled in windows with different binaries.
So copy the Houdini's numpy .... Program files\Side Effects Software\Houdini 18.0.348\python27\lib\site-packages\numpy
into Nuke11\pythonextensions\site-packages
(if you dont have Houdini, install the trial version and grab numpy from there)

Hey all,
Sorry for missing your message before @emartin8907.

I've pushed an update to the tool which might help. It's a custom python path knob. If you enter the path to the site-packages folder containing your numpy module, theoretically it will work.

Hope it helps!

Did a small update for python3 compatibility...

This is great! I can use it in Nuke Indie! One bug is that the Create Matrix button gives a NoneType error. I think the variable is being set to nuke.createNode() which is giving a NoneType output for some reason.

Is there a way to also use the color chart to estimate the gamma of a given frame? What's most important to me is matching the color gamma, as that is very important to the integrity of an aces workflow.

Hey @PinPointPing! Good to know about Nuke Indie support / behavior.

As for linearity: It is absolutely critical that the input image data is scene-linear. If it's not all bets are off.

If you are working with gamma-encoded or even worse display-referred footage, I would first take a look at how you can avoid this situation and work with scene-linear images instead. Otherwise your results will most likely be very poor.

Thanks for this great tool, @jedypod! I've just had a show that was using REDWideGamutRGB and noticed that this particular colorspace is missing even though the large stickynote inside makes mention of it. It wasn't a problem to convert everything to a supported gamut but in case you are still developing this tool, REDWideGamutRGB might be a useful addition.

@tiltX Thanks, it's been on my list forever to scrap that massive list of useless colorspaces with something more reasonable and modern. (When's the last time you used Ekta Space PS 5?) I just pushed an update which hopefully improves the situation.

I have nuke 14.0v3 and i am assigning numpy path from Houdini 19.50403-Py3.9 but when i hit calibrate, i get the following error in nuke:

module 'numpy' has no attribute 'transpose'

Can you point me to what i might be doing wrong?
