Easy Peasy :) This i the method I use in CS2. Everyone has there own preferences but here goes.......This is a quickie method :)

1st I duplicate the background layer then....Click on the half black/white circle in the layers palette and choose "Hue/Saturation"....Pull the saturation slider to the left to desaturate the image....Click okay... then click on the hur statuaration layer mask and use the brush tool (Colour black) and paint over the area that you want to put the colour back into. If you paint over something you don't want then change the brush colour to white which will undo this. If you get stuck thden give me a shout.

Good luck

Cheers
Charley :)

Thanks lads I was wondering about this myself. Tried in a post a while back but this seems to be easier.

Duplicate the background layer.

With the copy highlighted, desaturate the image and play with contrast/brightness etc to taste.

Use the erasor tool to erase the mono section, and reveal the colour orignal beneath!

Exactly what I do snorks... easiest way I think!

a quick way for me (from Stemmy if my memory serves correctly)

1) Open image
2) desaturate image (Image, Adjust, desaturate)
3) Click on history brush tool (brush with arrow - 5th box down on right hand side on tools - at least in CS2) and then click on the check box in the history window on the left of the step BEFORE you desaturated.
4) paint image with the history brush - whatever you paint will revert to the original colour

Hi - I also asked this question a few weeks ago - the approach I now use is the same as 'lostmysnorkel' and 'MTAL' (see example in the weddings section). I also got advice about using graphics tablets as I work mainly on a laptop and the technique isn't so easy with a touchpad! I got a graphics tablet - and it's brilliant - makes it so much easier!
Cheers, Mick.

I use a similar method - but one which I think gives a little more flexibility in adding / removing the colour or sepia parts of the image:


duplicate background (control / command J);
convert duplicate layer to B&W / Sepia etc using your prefered method;
add a layer mask to the duplicate (click the icon on the bottom of the layers pallette, 3rd from left, looks like a square with a hole in it)
then use the brush tool to paint black onto the layer mask to show through the colour of the background image beneath;
if you make a mistake, or even wish to come back to the image later, you can simply press 'x' to switch your brush colour from black to white and paint back in the mask;


The additional flexibility mentioned is because you can save the PS image with these layers and always update the layer mask at a later date. Whereas in the other method you are reliant on the history pallette which doesn't get saved with your document.

In addition, set yourself up an action to duplicate the layer and add the layer mask and it becomes really quick to start one of these images.

I also use a tablet (an A3 Wacom unit) - took some getting used to, but as I was advised would happen, I wouldn't try anything like this without one now. It's just so damn useful!

Anyways - hope this helps.

Yup, that is whee my method falls down a bit - the Layer Mask method probably allows for easier corrections, rather than relying on CTRL-ALT-Z and having to redo bits!

As for the tablet, I got a Wacom a while ago, and ended up buying a second, smaller one to carry in the laptop bag - haven't touched a mouse since!

Hi I Mickt - I would like a graphics tablet - after struggling with a painting tutorail and making a right mess with da mouse - what type do you have.
Ta - Phil
On the Colour POP subject - use the history brush method as above.
Just read rest of replies - and created a colour pop action layer method. Thanks.
Im going to dig up a test on graphic tablets.

Hi - after reading some other comments here I also went for the Wacom tablet - takes a bit of getting used to, but as I work a lot on a laptop I found it much better than the touchpad more or less right from the start.
Cheers
