In this episode of my video podcast I show how to correct colours in a photography with layers in the GIMP.




The 4th epsiode of "Meet the GIMP!" is out.

In this episode of my video podcast I show how to correct colours with layers in the GIMP.

For reducing the green tint of the image I add a layer filled with a bright magenta (white minus a bit green) and set the layer mode to "multiply". This reduces the green in the image proportional to the amount of green in each pixel. The amount of the effect can be adjusted by changing the opacity of the layer or changing the colour of the layer.

Then I add a bit of blue with a layer filled with a very dark blue (black plus a bit blue) and set the layer mode to "screen". Now the blue in each pixel is enhanced proportionally. This can also be adjusted.
