IMPROVE COLOURISED PHOTOS
In our photo, the door on the left 1 had been wrongly coloured green (including the glass) by Colorize. The door should actually be the same colour as those on the right 2 . To fix problems like this first open your photo in Paint.net.
To ensure you only change the area you want, use the Magic Wand tool. Click its icon 1 , lower the tolerance to around 30 2 , then click the area you want to change 3 . Lower the tolerance level if a bigger area than you want is selected. If you haven’t framed all the area, hold Ctrl and keep clicking to select more of it. You can use the Rectangle Select tool 4 to expand the selected area. Hold down Ctrl, then draw rectangles over the extra areas you need.
With the area selected, you need to choose your new colour. In our example, we clicked the Colour Picker tool 1 , then clicked one of the doors on the right to make that our selected colour. Next, click the Recolor tool 2 , change the Hardness and Tolerance sliders 3 to 100 per cent, then change the brush width 4 to a large size (20, for example). Now, with the left mouse button held down, move your cursor across the area you selected earlier to recolour it 5 .
