The method of adding colour to a black and white photograph is referred to as Hand-colouring generally either to heighten the realism of the photograph or for artistic purposes. Hand-colouring is also known as hand painting or overpainting. Usually,watercolours, oils, crayons or pastels, and other paints or dyes are applied to the image surface using brushes, fingers, cotton swabs or airbrushes. Hand-coloured photographs were most popular in the mid- to late-19th century before the invention of colour photography and some firms specialized in producing hand-coloured photographs. 

These are a few examples of hand-colouring of photographs.

I particularly like this photography because it is neatly done and there are different shades of colour on the dresses, It looks realistic.

Colouring Of Photographs

This is the original photograph I took, I then edited it in Photoshop to make it black and white.

I then printed out the picture so that I could paint it.

This is the final photograph after I painted on it. I have coloured in the bricks in the backrgound, coloured the hair red and added some colour to her jumper, lips and eyes.

I like the wall the best about this picture, and if I were to do again I would be a bit neater in the lines of the hair and the lips. 

Overall I am happy with this painting though.
