LR4: sparate presets for global tone curve and rgb tone curves

I love that since LR4 the tone curve is distinguishing between a global one and colour channels. I just wish that one could make separate presets for the global tone curve and the coloured ones.
This would be helpful because the global tone curve does not change the colours besides of de-/saturating while brightening or darkening tone ranges. On the other hand, the colour channel tone curves have a great influence to the image's colour distribution/balance.

It would be great to see separate check boxes in the settings of the presets creating dialog for global and colour tone curves just like noise reduction has, thanks in advance.

Good idea. In the mean time, the goal can be accomplished by editing presets using a text editor. Here are the tone curve settings:



settings = {


	ParametricDarks = -9,


	ParametricHighlightSplit = 90,


	ParametricHighlights = 9,


	ParametricLights = -9,


	ParametricMidtoneSplit = 41,


	ParametricShadowSplit = 15,


	ParametricShadows = 9,


	ToneCurveName2012 = "Custom",


	ToneCurvePV2012 = {


		0,


		0,


		255,


		255,


	},


	ToneCurvePV2012Blue = {


		0,


		0,


		255,


		255,


	},


	ToneCurvePV2012Green = {


		0,


		0,


		255,


		255,


	},


	ToneCurvePV2012Red = {


		0,


		0,


		255,


		206,


	},


},

* If you don't want RGB curve, remove the ToneCurvePV2012 = {...}, lines.
* If you don't want channel curves, remove the ToneCurvePV2012{color} = {...}, lines.
* If you don't want parametric mods, remove the lines beginning with "Parametric...".

Restart Lightroom for changes to take effect.

Hi Aron,

That's good to hear.

Yeah, it's just a UI limitation - there should be no problem using partial tone curve presets, assuming the syntax (e.g. commas & brackets) has not been befouled in the course of editing...

Ciao for now,
~R.
