Superb, please share your workflow if you get a minute

Sure its as follows

* Screen transfer function

*SCNR tool (remove green)

*Fast Rotation

*Dynamic Crop

*DBE

*Background neutralization

*Canon banding tool

*colour calibration

*Histogram transfer tool ( i do 2 clones for masks

*channel extraction tool (on 2 clones extract luminance layer for masks)

*colour saturation tool (masked)

*Multiscale medium transfer tool (inverted mnask, change to 6 layers disable first 2 noise reduction on next 4)

*HDR tool (masked)

*Contrast curve (masked & inverted mask until happy with image)

*ACDNR tool (inverted mask set std dev to about 6.6)

*ACDNE tool (masked set std dev to about 3.0

*Curves (do on separate channels masked & inverted masked at until you are happy)

that's everything i did to the image in a nut shell
