Black And White to Colour
This is not a tool on photo-shop that you can use, it is more of a manipulation of layers and colouring to add in the effect of colour into your old black and white photos. To transform your old colourless photos into brand new colour pictures, you must uses a the Auto Selection tool, to select the area you want to colour. The selected area will have to be the same colour. Then you go to your layers bar, and scroll down and select Photo Filter. Then choose the colour you want and the opacity you would like. The program takes into account the shading and adjusts appropriately. You must repeat with other parts of the picture until the whole picture is coloured.
