Processing a green screen image

[bwolford]

I've taken a picture of my daughter against a green screen. When I use the selection tool to select her, I still have remnants of the green screen all around her. I used an eraser with a soft edge to remove some of it, but I lose a lot of detail. I've posted a shot here that shows the remnants. Look at about 3 o'clock from the center of her face.

Any suggestions for softening the selection or removing just the green from the greenscreen?

Here's the original.

The next step is modifying the green screen image to look like it could have been part of the original... I leave that for another day.

Brice,
I think there is a way something about when selecting you set the boundry but for the life of me I can't remember. ops: I will dig thru my notes or someone else will know how to do it.

Its going to be tough in the hair area. I think maybe what Sarah was refering to in her prev post was, once you have made the selection go to Selelct>modify>contract. Contract 1 or 2 pixels and then do the same with Select>feather same number of pixels. Im not sure if this will help in this case but worth a shot.

Your daughter is beautiful! I tried it a little differently - I used the magic wand to select the green. I magnified it a bit in the problem areas and set the magic wand to 25 tolerance. Then I selected the inverse - contracted it one pixel and Ctrl + J to put it on a new layer.


May I ask how did you set up the green screen? Is it a special fabric?

Mary, that fabric is super special. I went to Wal-Mart and bought 2 yards of the ugliest green fabric I could find. It cost me all of $4.37 ++. I should have ironed it and placed it more carefully. I was just fooling around.

All the methods seem like a good idea, especially the contrac then feather method. I'll give it a shot.

Once I have that mastered, we'll need to move onto part two to better blend the images so that the photos look a little more realistic. I'll post my results using these methods and we'll see if it's starting to look any better.

Walmart eh? Now that I live close to one I am trying to find reasons to go there and you have just given me a good one. I am definitely going to try it out. Thanks for sharing your super high tech photography tool.

Ah Wallyworld, gotta love it. I found a king sized blue sheet on sale for 6 bucks for a handy background and some nice gray felt pretty cheap (tho the felt was only big enuf for head shots)
