On bright sunny days capturing landscapes may result in a washed-out sky – especially if you’ve exposed for the ground. Many photographers get around this problem by using a graduated filter, which are dark at the top and fade to clear at the bottom. Coloured ones add a tint to the sky, while neutral ones simply reduce the light entering the lens. Although you won’t be able to bring back any lost detail using a Photoshop graduated filter, a more interesting sky may be created.
