Hi Mark. As a photographer, i have always called this localised, or spot colour. A number of ways of doing this. As Ray mentioned, layers, but use the Eraser (E) to rub out and reveal the colour beneath. Make sure that you change the Opacity in the Layers
palette to see what colour you are revealing.

Another method is an Adjustment Layer (non-destructive editing), and is probably the most effective way. 'Layer - New Adjustment Layer - Hue/Saturation'. Desaturate the image. Make sure that you have black and white as your colours by hitting the 'D' key, then toggle with the 'X' key to get black. Choose your Paint Brush and start painting to reveal the colour. If you make a mistake, hit 'X' to choose White and undo. You can change the pressure of the brush, as well as the opacity of the Adjustment layer. Change the size of your brush with the { } brackets.

Hope this helps.
Cheers
Jon

Subject: ?photo/photoshop colour saturation terminology?

can any photographers/photoshop wizards help me with a bit of terminology.

when you completely turn down saturation in all colours except one -
so that, say for example,  a portrait shot will appear as  a black
and white except for her red lipstick which will still show as
red..what is this technique called?

Hello Mark

First of all I like to say HI as I have only joined a couple days ago.

Im not really sure what its called to keep one colour in the B/W photo
But when I create a B/W photo with part colour I use Layers.
I load the photo and create a second layer
The first layer I make B/W
The second is in colour and I make everything transparent except the lips
There are other ways but this works well for me

Regards

       Ray
