I have an image of two women against a green background that I need to change to a white background. The women have fine wispy hair that needs to be isolated. Ultimately the image will be part of a large poster, so it needs to look really good against the white. The photo also needs to be "prettied up", i.e. use PS levels and effects etc., to make it look as good as possible when printed. I have attached a lo res copy of the image - I'll upload the original to a server (300 dpi, 3413 x 2560 pixels) .
Thanks for looking and lmk if any questions.
