Grey-scale transfer?

[JJ McKool]

I've been tryin ta figger this out, but I dont know if i can, I was wondering if you can switch something in photoshop to grey scale, without actually losing the colours, so that u can do shading, and then switch back, and finish the colours. I think better with shading when its grey-scale, I guess. I've just started usin CS3, and its a huge step up from Limited Edition 5.0, had to cuz I got vista now, so I don't know most of the tools all that well, and its a lot to take in I guess.

don't know about cs3 but in cs2 you can use a hue/saturation adjustment layer to make non-permanent changes to the saturation (found under the icon that looks like a half black half white circle at the bottom of the layers menu)

Alternatively, you could duplicate the image (right click on the layer > duplicate layer) and desaturate the duplicate (Image > Adjustments > Desaturate). Then you could just turn the grey-scale layer on and off as needed.

If you need to work with more than one layer like this, you could flatten the image, cmd-a (select all) cmd-c (copy), cmd-z (undo select all and flatten, so it's back to being in separate layers) then cmd-v (paste). Then desaturate that layer.
You would now have one layer, compiled of everything that is black and white, and underneath that is all of your other layers in colour.

Hope that made sense...
