To produce a photo with selective colour, you first need to convert the photo to Mono. This must be your first piece of post processing on this photo, do not crop the photo until you have completed the selective colouring. Follow the steps below to convert your photo to mono, then see the details at the bottom which will show you how to return colour to specific areas. Converting a photo from colour to mono can be done in a few simple steps.
The first is to select the photo your looking to convert. You then need to Select image in the top tool bar, then select adjustments > Channel Mixer
Once the Channel mixer has been selected you need to check the Monochrome box as seen below.
Your Photo will now be converted to Mono, but there is one more step here that really requires your own personal adjustment until you get your desired effect. I personally change the Colour percentages to Red 40% - Green 30% - Blue 30% and then tweak adjustments until I obtain the effect I'm looking for
Now your photo is converted to mono, you only have one simple step to enhance your photo with selective colouring.Using the history brush and painting over the areas where you want the colour has got to be the easiest and quickest way of doing this.
Now carefully go round the area of where you want the colour.
