Best Node Method for reducing color range for Detail Maps.

oXYnary

Need to fit color range into half of its current. (So like 4 bit vs 8bit)

How would you solve this?  We are using a Blend with a 16F 50% grayscale at linear dodge. Then doing a 16F grayscale of that result with Multiply.  At the end we reduce to 8bit.  It gives us close results, but I keep thinking we can do this with less nodes.

 therefore detail authoring needs to be (1+inDetail.rgb)/2 aka 0.5+inDetail.RGB*0.5in order for detail maps to allow for brightening as well as darkening albedo results, the unpack equation is <code>albedo.RGB+detail.RGB*-1.

Histogram range?

That only works with grayscale images.  Is there a node like that for color?

Use 3 of them and some rgba split/merge nodes to make your own

Auh, yes, Thanks!  Made a sbar input/output with them so can put in as a node from now on.
