Hand colouring with Photoshop

There are several ways to simulate hand colouring of black and white images using Photoshop, so I have been using different methods to see which is best. 

Conclusion - depends on the subject and the image.

Method 1

Starting with a black and white image.

Add a new layer

Set the MODE to COLOR

Pick a oft paintbrush

Make sure the BRUSH is set to COLOR

Set the opacity to around 60%

Pick a color and brush on the layer

These lilies started life as a pinhole b&W film image and were hand coloured on Photoshop using this method.

Method 2

Starting with a colour photo

Open the color version

MODE - Adjust_ Desaturate (or better - select a B&W adjustment layer if you have a later version of PS)

Use the History Brush on the adjustment layer to restore the colour

OR create a layer mask and pant with black on the layer mask.

These were done using that method
