clipped from www.ephotozine.com Replacing Colours in an Autumn Scene using Gimp Replacing Colours in an Autumn Scene using Gimp - Michael Bates shows us how easy it is to replace the colours in such a scene without having to spend forever playing with the threshold. One of the most useful tools in Gimp is the Colour Select tool, which allows you to select all of one colour and those similar to it in one click. The main application of this tool is to replace colours in an image, but what about images where you want to replace a range of colours? In this Autumnal photograph the trees at the top of the image are a range of oranges and reds, yet those at the bottom are still green. If I wanted to replace those no amount of fiddling with the threshold setting on the Colour Select tool would allow me to only select the green leaves; I'd always select too much of the image and colour the branches by accident, or I'd not select enough and green leaves would show through.
