I only did the change on the right part of the picture. If that green appears on the darker tone or lighter white tones, you can also modify it on these. You can also select the "neutrals" to remove that green from the midtone equally. There it's possible to select the green hue, and lower the blue and yellow there. In this case you should use this trick and then adjust the colors of your total image as you normally do.įor this, you can go in the menu "image" and then "adjustment", and then select "selective color". If you have a well calibrated display, that's not a big deal and anyway you'll probably need do it anyway to adjust your contrasts and adjust the colors. If you decide to simply do this on the whole picture because that green glow is everywhere, you'll need to adjust your levels again. You can see I didn't do this on my picture, and half the face You're done! Otherwise this will change the colors on the whole On another layer and blend it again with the rest of the image once Note that for this, it would be better to isolate the top of the head

With this method, you won't need to modify the pixels, only their colors. To modify the colors, instead of using the clone stamp, you can also select each hue individually and desaturate them. Stop at the step about the matting or stamp tool and read the suggestions below. I personally like using a 85-89% one depending on the size of the image. :)ĭo all the steps Ryan mentioned about the layer mask or simply create a layer mask as you normally do don't use a brush that has too little hardness or your edges will look blurry. But if green must be used, have your subject stand further from the background to avoid reflections (but you probably already figured that out). You may need to adjust overall hue/saturation, and possibly the yellows, too.īlue backdrops will give a more natural looking reflection, since we're used to sky colors reflecting on skin. But all require careful masking.Īdd yet another Hue/Saturation layer without a mask, and adjust the reds toward the green side and slightly less saturated. I mostly use Levels, Hue/Sat, and in drastic situations, replace color. And Hue/Saturation may not be the only type of adjustment layer you use. Sometimes several layers with subtle changes are required. Carefully paint white onto the mask where you want the effect applied, adjusting your brush size, edge softness and opacity as needed.Ī stronger version of this technique may be needed on the greenest portions, using a new adjustment layer/mask. Make a Hue/Saturation adjustment layer, and adjust the hue until you're happy with the results around the top of his head. Unfortunately I don't have access to Photoshop at the moment, so I can't make screen-grabs to illustrate this technique. It's a great resource for stuff like this.

I only did the top right of the head so obviously there's still quite a bit of green in other portions, but here's a quick look at how it can get:.

I'd suggest using new layers for different areas so its easier to manipulate and gives you more control later:

Using a soft brush (I use around 65% Hardness with Wacom pressure for size) touch up the problem areas on the face.

Make sure it's set to Sample All Layers on the top:.

(You might even want to duplicate it at this point to have a copy) Now on the layer panel click the actual photo so you're no longer on the Layer Mask. I used Magic Wand for those holes and then again Brush for some find touch You'll also want to get rid of the gaps in the arms. Use a Brush to do some cleanup particularly around the feet which wasn't as good of contrast. To do that just click on the mask portion of the layer in the layer panel. Notice the box around the Mask on the right, not the Photo on the left.

You should now have a Layer Mask in your Layer Panel.

Now go ahead and change your Channels back to the RGB image by deselecting that Blue Channel Copy.

Select > Focus Area and change the output to Layer Mask.

Now you can use Curves or Levels to bump the contrast a little more.

Now the pants and skin are about the darkest things, the shirt is by far the lightest thing, and the background is a midtone. Select the Blue Channel which will give you the most contrast.Go into Channels (it's attached to the Layer Panel by default).Alright well first off I wouldn't use the Magic Wand or Color Range.
