# Best Node Method for reducing color range for Detail Maps.

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.

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

`in order for detail maps to allow for brightening as well as darkening albedo results, the unpack equation is ``albedo.RGB+detail.RGB*-1.`

therefore detail authoring needs to be `(1+inDetail.rgb)/2`

aka `0.5+inDetail.RGB*0.5`

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