How to Remove Colour Cast in Gimp

A very common problem with photographs is colour cast – a consistent deviation of colours from expected values.

We get blue colour cast when photographing outdoors, we get a pale sickly yellow playing throughout pictures captured indoors under electrical lighting and so on.

Whilst colour cast can seem to overwhelm a photo, it is thankfully easy to deal with.

In this video we take a very damaged photograph and cure it of its colour cast and restore the picture’s whites in the process.
