Colourization

When saturating an image you can also choose to use the colourize tool that alows you to change the colour of the image. I am going to change the colours of each individual building and change the colour of each of them. To do this you need to use the magic lasso tool or the straight line tool. The straight line tool is a lot easier in this picture because the building are very straight. After selecting the individual building you use Ctrl + C to copy the section and then you use Ctrl + V to paste it as a new layer to work with. Once the layer is selcted you click on the hue/saturation button where a tool bar will appear. The tool bar should have 3 bars on it and we are going o use the top one which focuses on saturation. However, you need to click on the colourise tool which will change the amount of saturation into colour. By moving the toggle across the bar you will see the differnt colours uintill you find the colout you want to use then you click on ok. You should now be left with an image where the section you hav selected has been edited. To edit the rest of the buildings you folow all the same steps as above but using differnt colours to give a very good effect.
