I am learning photoshop myself at the moment (i started today)

However I am keen to learn one feature. How do I (in simple terms) manage to have a black and white photo with only a small portion in colour, e.g. Like Steve got the rear lights of Iona in red beside the water.

Thanks in advance guys.

The ultimate (and extremely easy!) way to do spot colour:

De-saturate / gray scale / apply B&W tones to your desire.

Use history brush to bring back colour on selected objects.

Thats it!



Actually there is another way, which can, depending on the specific photo, be much easier and produce better results. Go to Select>Color Range. You can then select a colour (or multiple colours by holding down the shift key), and the tolerance with which they are selected using the slider bar. There are a few different Preview modes too, so you can see exactly which bits you are selecting. When you are happy, press OK and you will have evrything you wanted selected, and all the edges will be feathered too.

This techniques is made or broken by the photo you are working on. You want the colour that you are selecting to only appear infrequently in the picture, for example a bunch of red roses being held by someone in a suit would be good, because the only red is in the flowers. A grey car on a dull day will not be able to be extracted using this technique, ever.

Actually, to be more specific, it doesn't matter if your chosen colour appears all over the photo, as long and it does not adjoin the area of that colour you want to isolate. Once you have made your selection (including the unwanted bits) it is very easy indeed to bin th ebits you don't want by doing a negative selection with the marquee/lasso tool. This is done by holding down one of the modifier buttons whilst selecting, I think it is CTRL, but a minus sign will come up next to the tool cursor symbol as opposed the the plus sign when you hold down shift.

I hope that all makes sense...
