There's also the hueshift node which allows you to rotate the hue by any amount desired. On Fri, Oct 7, 2016 at 3:17 AM Gary Jaeger wrote: > Boom! that’s it. Thanks Nathan! > > *Gary Jaeger */ 650.728.7957 direct / 415.518.1419 mobile > http://corestudio.com > > On Oct 6,

Inverting the hue channel is just flipping the values around 0.5. Try an Expression node with `(r+.5)%1` as the red channel expression to actually rotate the whole range. -Nathan On 10/7/2016 4:52 AM, Martin Constable wrote: > Perhaps it is inverting according to the Muncell colour wheel? > >

Perhaps it is inverting according to the Muncell colour wheel? I believe that this corresponds roughly to Lab space. > On 7 Oct 2016, at 12:47 AM, Gary Jaeger wrote: > > Yeah, though it’s interesting that it’s still something different than doing > a Hue invert in

Yeah, though it’s interesting that it’s still something different than doing a Hue invert in AE. I’m not sure why. For instance in AE a hue invert turns a cyan to a magenta. In this method, a cyan become sort of aqua-ish. Gary Jaeger / 650.728.7957 direct / 415.518.1419 mobile

Do you mean invert the Hue channel as in the H of HSL or HSV? If that's the case you can do Colorspace ( to HSL or HSV ) -> Invert (red channel only) -> Colorspace ( from HSL or HSV). That help at all? On 10/06/2016 09:38 AM, Gary Jaeger wrote: Any ideas on matching the Invert > Channel, Hue

I just tested and compared it with one image. Something along those lines? set cut_paste_input [stack 0] version 9.0 v8 push $cut_paste_input Colorspace { colorspace_out HSL name Colorspace1 selected true xpos -208 ypos -143 } Invert { channels {rgba.red -rgba.green -rgba.blue} name

Do you mean specifically just inverting a single channel? There's an "invert" node that'll do this, though you will want to shuffle out your desired channel first. If you meant something else, I apologise! It's been a little while since I used AE. On Thu, Oct 6, 2016 at 5:38 PM, Gary Jaeger

Any ideas on matching the Invert > Channel, Hue effect from AE? I looked on nukepedia and couldn’t figure it out in the various tools in nuke. Thanks! Gary Jaeger / 650.728.7957 direct / 415.518.1419 mobile http://corestudio.com
