Hand Tinting
Do you guys remember the B&W pictures that were hand painted with color oils?
Here's a way you can imitate that look in PS if you wanted to try it.
Open the image you want to work on.
Click on the adjustment layer from the bottom of the layer palette, the circular black and white icon.
Select Black and White.
You are given some options to tweak the color filters to enhance your B&W.
When it's to your taste, look at you upper layer. It should have a layer mask, the white rectangle to the right in your layer. That is your layer mask.
Select your Brush from the Tool bar and making sure that Black is your foreground color in your Tool box, reduce the opacity of your brush to 25% or any percentage to your taste and paint black on the part where you want the color revealed. Do not let go of the mouse while you are doing this because it would alter the percentage of opacity.
You can also change the color you painted by going to Hue/Saturation, using the dropper (hand) to select the color, then moving the Hue slider to get different colors.
