How would you process this? green

how to deal with the green lights lighting the background ?

this is one of the reject shots, but all the shots had this background colour.

Duplicate the layer, then go into channels on the new layer and reduce the green channel's saturation, then mask the person back in?

It would depend on several factors. Such as what software you have, and did you shoot RAW. Given a RAW file and using full ACR or LR for processing the RAW I would try the following. I would use the HSL sliders and using saturation and employing the Targeted Adjustment feature I would then simply pull down the saturation. The Targeted adjustment is very good at reducing the necessary channels by just the right proportions to correct almost any colour. This should also reduce the colour spill reflected by the subjects skin too. Although it is a global adjustment this technique seems to work very well especially with bright 'unnatural' colours.

If you are limited to working with RGB files (JPEG say) but you still have ACR/LR then you may get a similar result, although a RAW file would be better. If you don't have ACR/LR then the previous posters suggestion regarding using layers to reduce the saturation of the green channel and masking it out is probably the next best option. I would just use a saturation adjustment layer and mask that, rather than the full on layer duplication method.

using RAW lightroom.

to add, trying to find a quick (ish) solution without having to spend ages on each photo

ill have a go when i get back later at the above suggestion, many thanks ..

If you are looking for a quick solution...convert to B&W.

This is easy to fix in PS. Duplicate the layer. Go to Filters, Blur, Average. Create Curves level layer. Use the grey/middle eye drop and click on Average layer. The colors will shift a neutral grey, to compensate for the green cast. Deselect the Average layer. Click on the mask (curves Layer). Press ****+Backspace. Fill with 50% grey. The skin tones should be neutral, and the green cast will be tamed.

I use Aperture so select the colour and change hue or saturation, no need to mess about with layers all done in under 10 seconds

wow. thats done the trick ^, thanks whiteflyer (and everyone else)

Why would you want to change how reality looked?

Presumably you want to correct the green spill on the skin and hair (and maybe the black shirt) and not alter the background.

The green lighting appears to be coming from behind and both sides, resulting in sidelit and backlit spill. For each of the three areas to be corrected, try selecting a small area of that color (for example, for skin try selecting the forehead or left cheek) that is not contaminated with spill light. Then Blur> Average to the average color. Make a solid color adjustment layer in PS of that averaged color and set the blending mode to Hue. Paint over the areas contaminated by spill. Repeat for the hair and the shirt.

If you use solid color adjustment layers, you can tweak the color of each layer to remove cast, etc. So if the "Average" color still has traces of the green, you can essentially neutralize it with the color picker for the Solid Color adjustment layer.

Before/After attached.

that is a really good question ... answer is i dont know, just seeing everything green looked a bit wrong , but i suppose leaving it as it was wouldnt be bad...


Thanks Kirk, yes but the goal was to not spend much time on each image, there are lots of images and i wanted something quick.. removing the green channel in lightroom solves the problem for now.
