How To Colorize a Black and White Photo in Photoshop

I spent some time the other day experimenting with colorizing a black and white photograph. The image I worked on is a photo of my Grandad during WW2. The original has that washed out sepia look to it, as you would expect from a snapshot from the 1940s. But after scanning and processing it in Photoshop, it’s brought to life in full colour and much better contrast, which really helps you imagine the scene for real.
