This new macro lets you define black and white point shift by picking colors from a reference picture.

Neat idea. Thanks Gringo.

Clever implementation. Very nice. I'll have to benchmark this but I think a straight colormatrix would render faster but offer the same interface.

Thank you guys!

The idea itself isn't new, but hopefully, it'll be useful in Fusion for you :)

Thank you.
It will be interesting to test the alternative.

Yup, very clever, will test this in the next few days ;)

ColorMatrixTransform is 40% faster than ColorCorrector.

I haven't been using a whitepoint/blackpoint setup as you have, but instead hooked them up to a special tool that finds the min and max of each channel over a sequence. You can do the same thing with a Probe and Duplicate tools, though. So it can effectively cancel out any color bias over the whole clip without picking anything. It DOES however require conservatively exposed images. If you have black or white baked into the image already then you have to resort to manual adjustment as you have set up in your macro.

EDIT: Of course, this is assuming that the CC is hidden in a macro, so the other things it does (which are slowing it down) are not being used. It might be useful to, instead of making a macro, add the color wheels as user controls to the levels tab and keep all the other CC controls available, so you could use it as a CC and not a WB.

I just noticed that by holding shift when dragging the color wheel you can restrict the movement to only hue or saturation  :mf_w00t2:

I've never noticed before (or tried, for that matter).

Good to know!
Maybe, once I have some more time, I'll rework the macro.

It might be useful to, instead of making a macro, add the color wheels as user controls to the levels tab and keep all the other CC controls available, so you could use it as a CC and not a WB.

I've done something like this before, connecting Gamma Gain and Brightness to color wheels for an experiment. Maybe, if I hide the original G/G/B controls, CC will look more explicit.

I remembered why I didn't finish this CC refinement last time :)
It's impossible to have different user controls (color wheels in this case) exposed for Shadows/Midtones/Highlights and Colors/Levels/Histogram/Suppress.

So, I whether loose Shadows/Midtones/Highlights switch or overload the interface with the color wheels.

It's only in Eyeon's power to reduce the amount of "what-else-this-CC-affects-in-the-numerous-subcategories?" clics.

Maybe, I'll try and make a PrimaryGrade macro which will have only B/WPoint, Gain, Brightness, Gamma, (Contrast?) - all with color wheels and possibility to define Ranges.

So, here it is, a macro which has a full set of controls for primary grading.

  • This version works correctly with B/W points exceeding the 0..1 range.
  • Additional "... Level" controls added to adjust all the three channels globally. Please, vote for the naming (press "Delete My Vote" if you've voted in the previous poll).
  • The new Pre-Saturation control adjusts the initial image's saturation before all the other operations (if you set it to 0, but adjust other controls for separate channels, the image will have saturation all the same).
  • Gamma control raises the color to the power of its value, in other words, performs the Gamma operation.
  • Brightness control adds a value to the color, just like one in a CC or BC, raising both black, white points and everything in between.
  • Separate tabs for Master/Shadows/Midtones/Highlights to isolate adjustable ranges based on the luminance.
  • Added a possibility to clip a user-defined range (not only black and white).

 I just checked out the primary grade macro. Great job, Gringo!

A version with alternative controls naming.
What do you think?
