Create New Curve layer with Algorithm options (3) by script?

[powerful_Zephyr5EF9]

hi everyone,

I want to create an adjustment curve layer with "Find Dark & Light color" algorithm option by using script.

The image is described as below.

Please guide me the exact command.

I appreciate your help

You're going to need to change 1 key value from the previous code that I provided here:

https://community.adobe.com/t5/photoshop-ecosystem-discussions/create-new-curve-layer-with-algorithm...

descriptor6.putBoolean(s2t("autoContrast"), true); // Enhance monochromatic contrast

I'll post it later when I have time, unless someone else posts it first.

hi @Stephen Marsh 

I have tried many keywords, 

ex: autoColor, autoColour, autoDarkLight, autoTone, autotone ...

or with any keyword I can think of but it doesn't work.

I also searched on forums and google but it doesn't seem to hit the mark.

please guide me with the keywords in the algorithm section of Option2, Option3, Option4.

@Stephen Marsh 

luckily, i tried to create action for these options and when i looked at the details written there i was lucky to get 2 keywords.

With option 2
"auto" for option 2 -> works

With option 3
"autoBlackWhite" for option 3 -> works

but when i tried to add checkbox "snap neutrals middtone"
I combined keyword: "autoBlackWhitewithAutoNeuTrals" but it didn't work.

With option 4:
keyword "autoEnhanceBrightnessAndContrast" also didn't work

Please help me fix the two keywords:
autoBlackWhitewithAutoNeuTrals
autoEnhanceBrightnessAndContrast

The four auto options are:

// Enhance Monochromatic Contrast = "autoContrast"
// Enhance Per Channel Contrast = "auto"
// Find Dark & Light Colors = "autoBlackWhite"
// Enhance Brightness and Contrast = "autoMachineLearning"

So, building upon the original code in your previous topic:

// Set the layer opacity
//app.activeDocument.activeLayer.opacity = 50;

@Stephen Marsh  thank you very much, option 4 already work!

luckily, i accidentally discovered that it is possible to tell photoshop to keep neutral points with the following command line: 

descriptor6.putBoolean(s2t("autoNeutrals"), true);

it actually created neutral points:

Great stuff!

I couldn't get it to record, but I just went back and tried again and it now works! I have updated the previous code.
