Displaying primary colors as their secondary equivalents in LR?

[raphaels28255986]

Hi guys,

Is there a way to display (and then print) images in their secodary equivalent colors instead of their primary RGB colors?

So that reds would display as cyans, blues as yellows and greens as magenta? That would be awsome.

Thanks a lot.

Create a new mask using a paint brush. paint it solidly at 100 flow and density over your entire image. Set the only edit in the mask to a + or - 180 degree shift.

An inverted Tone curve will do this.

I believe @Jao vdL  has given you the correct answer.

The inverted tone curve creates a negative image, where darks become lights and vice versa.

Yes exactly. complementary colors are 180 degree shift in Hue in the HSL color system apart, so using the mask system and shifting Hue of the entire image by 180 degrees will accomplish what OP wanted to have happen without inverting the luminance of the image at the same time.

Thanks a lot Per. I will try this at the next opportunity.

And think of both of you guys 🙂
