Deducing Dehancer
TLDR: I was curious what it did when I told it to do nothing… So I clicked disable all features and look at a cube!

As promised some of the things I used in this video:

Dehancer Approached Me
I don’t know why really… but as a full disclosure on doing the review they requested. I turned down the option to have an affliate link. I would feel awkard to do a review where I got a benefit if you purchased the product. How I could I be truly unbiased. I orginally tested it out and wasn’t convinced to buy and so I thought I would give it another go.
What I Found
My initial expolorations were to try to see what it did from a forensic point of view and I was suprised to find that despite thier claim that it uses the whole DW/I pipeline that when you turn off all the features and give it a color space other than Rec.709 or Rec.2020 that it did some gymnastics and gave back a cube that was quite contorted
You can see in the video what was going on. But in talking with other colorists and trying to get information out of the dehancer rep the best guess was there was some sort of tonescaling operation going on to go from DW/I to an SRGB colorspace and back. The net pipeline is DW/I but you do not get the same cube back when no options are selected.
A close match would be to use Davinci CST’s to go from DW/I to P3D65 using Davinci Tone Scale and then go back to DW/I
I know that some people use it soley for grain or halation but I personally would like those things to be added in to the image before my transform to display space not after.
I’ll keep playing around with it and I have another video planned comparing it to a couple other options if I ever get to doing it.
