Selective Colour in Photoshop

mr pharmacist

this has probably been covered at some point before but i trawled through a few pages and couldnt find it if it had been covered.
does anyone know how you create an image thats b&w but has one element of the photo still in colour. saw a pic a while back thats black and white but the persons red shoes were in colour.
im using photoshop 7.

Maybe there's another way but I'd probably just create a mask around whatever I wanted to keep coloured and desaturate the rest.

Really quick and easy :: lasso tool around red shoes, select inverse, desaturate.

For better results google for help with photoshop image masks.

what i do is duplicate the layer and select the top layer. use the pen tool to select around what you want(pen tool gives you the option of feathering, rather than the lassoo tools hard pixel edges)then go into path selection. select your path, input your options etc. you'll have your picese of the image selected, then from one of the options on the menu bar select inverse (im away from my computer now so im not too sure under what it is) and then press delete. its a longer way of doing it but you have much more control over how it turns out.
apologies for my backwards words just home from work and im knackered and too tired to edit.
