Have you ever wanted to find the average colour of an image, or even part of an image ?
It’s easy to do – Filter > Blur > Average, will take all of the colours in your image (or in a selection), find the average and fill the image (or selection) with that colour.
Why is this useful you ask ? – In this series we will outline many ways in which it may be used.
First up – it enables you to do a ‘rudimentary’ colour cast correction. We’ll build on other uses for the process in subsequent posts.
Make a duplicate of the layer, then
Filter > Blur > Average on the duplicate,
Invert it – Cntrl I (Cmd I on a Mac)
change its’ Blend Mode to Color and
As a start point, decrease the Opacity to around 40% – then adjust to taste.
NB :: This works equally well using Photopea, Photoshop and Affinity.
If you have any actions, presets, tips, worked examples you would be happy to contribute and help others off to a good start with their photo processing, please get in touch – pay your knowledge forward !
