Creative challenge 007: Knocking out a background

[DannyRaphael]

We haven't done one of these in awhile...

Challenge: Replace the green background with something interesting...

Your choice of program / plugin / and/or tricks.

Please describe your method so rookies can follow along.

Duplicated image. Made a copy of green channel in RGB. Used levels on the a channel in LAB. Copied and pasted into Green copy channel. Not too happy with chosen background or green remnants left in hair..but it's a start.

Cheers

Probably the easiest with this type of background is Replace Color.

Made a mask from channel mixer - monochromatic, dodging and burning and used the desaturation brush to remove some of the greenish tinge on the hair ends

[Gary Richardson]

Made a mask from red channel.

Main problems I had here, was the disparity in resolution between girl and new background, and difference in lighting between indoor and outdoor (not overly pleased with result, but don't have time to play too much at present).

Thought I'd have another go at this as the first one was not too clear. Anyone care to reveal their method for removing the green colour cast off the ends of the hair? I used a mixture of colour and low opacity eraser.

hmm, wouldn't say, that THIS background is interesting, but it suits here, i think.
i didn't do much, changing (dear me, i have NO idea how to say that in english..->) saturation of green (?), adding blur on the edges and casting inner shadow were main actions here. oh, and after doing this to that poor woman and merging her with (or to ) background i played a little with curves.

second attachment is for blue-lovers

Love the way you captured the wisps of hair, tell us how did you remove or avoid the green colour cast

[bert de wolff]

oops, what will get you are the things you don't see coming

bert (who couldn't get rid of the greens either)

Used the red channel for masking and after merging the layers pulled the hair strands out with the smudge tool to hide the green fringe.

Hi Cassidy,

I cheated a little with this one.

After creating mask, there was quite a lot of green bleed, so I created a new layer set to colour mode. I then Ctrl+clicked the girl layer so that her outline was selected in the colour layer.

Now, using a clone brush, I sampled from good colour areas and painted green hair and skin.

By using clone tool instead of paint brush, you don't have to resample as much, as sample point moves with you.

Use Ctrl+H to hide selection dots (which get in way) don't forget to undo this after you've finished.

As it is Halloween!

I added the lucky lady with the halloween stars!

[Duv]

That's pretty sweet Elle! Even like the Halloween cleavage.

Very cool, Legacy~art.

Here is mine. I used the select color (green) and then deleted the green. I used the quick mask to clean up edges, adjustment>replace color selecting green, move slider until green is replaced with a matching hair color.

After I put her into a new background, I adjusted her color, and highlight to try and blend her into her new environment.

Sarah's bored!

1.) Selected green, selection/modify/smooth, selection/modify/contract, deleted green
2.) Select color range, selected remaining greens and made them match hair.
3.) Played with lighting.
4.) Matched color to the "Jaws" layer
