"Alternative to CNX2 white and black control points?"



This is the wheelhouse of my photo editing. I do it right after NR. I seldom need to touch WB, exposure or worry about colour casts if I use this. I set black to zero, white to 250 and often reduce luminance on the White Point (down to about 98%). I'd like to know where else to find this level of control?

Jim

Jim it is in every product I have ever used. In many cases you will find it in with the curves adjustment.

I can ballpark it in Photoshop CC using a threshold layer and colour sampler and then Curves or Levels. I'm not getting anywhere near the precision I got with CNX2.

In ACR you use the black and white sliders when not in ACR you can use the black and white eye droppers in the curves or levels module. The key is once you select a dropper. hold down the ALT key and it will show you the clipped image for that color to help you select.

In ACR you can hold down shift and double-click the black and white sliders to apply the black and white points automatically. But I want to set the white point at (250,250, 250). Not sure how to do this in ACR. In Photoshop levels it is easy, but I can't confirm that ACR is using the same white point.

Jim, you can do that in ACR using a Point tone curve:



Just drag the upper-right point as shown. For greater precision type the values into the boxes at the bottom. You can do the same thing at the bottom if you want a black point other than 0.
