How do I remove greenscreen from a background?

I am using the "select color range" to remove my green screen from the background. I selected the middle eyedropper (because the green screen was unevenly lit) and "invert". The problem I am having is that the subject is also being selected. How can I just remove the green from the background without affecting the subject?

Just uose any selection tool. Quick Selection, Magic Wand, Color Range, Quick Mask, Pen, Lasso (depends of your subject) you can also use channel,

If you select your subject (in new version of Photoshop you can even use Select Subject Command) then go to Select & Mask Command to adjust jour selection. If you do if use CTRL+J and move your subject on a new layer.

Then you can select background and change color any way you want. You can even drag and drop new background from any image or selection

Choose the Quick Selection tool.

In its Option Bar click on Select Subject.

When the marching ants appear outlining the subject click on Select and Mask

Adjust if necessary and be sure to click on Decontaminate Colors

In Output to: Chose new layers with mask.

I don't see "select subject". Only "select and mask".

I tried the "select and mask" and it seemed to work a little better but I'm still left with a fuzzy green outline around my subject. I tried the "refine edge" tool and it erases the subject as well.

I suspect the subject edge is not in sharp focus, which is deadly in green screen. Post the image so that we can have a more accurate idea of problem. Also, tell us what version of PS you are using the and OS
