well,may someon please tell me how do i get the update for photoshop with the colour replacement tool
You buy it? I'm not sure what exactly you're referring to, but you probably need to buy the new version.
Right click on the brush icon and select color replacement tool.
Color replacment has been around at least since cs2 no?
well, i HAVE photoshop, but i have "Adobe Photoshop 7.0". how do i update it?
You need to pay some updating price, dunno, not sure. And if yes, you know Adobe's prices ...
