There are two simple actions that will make your photo change the seasons from summer to autumn or from autumn to summer, on some of the images the actions may look over saturated, you will just have to play with the brightness and contrasts and it will look just fine.
My actions were created on the version CS4 of Photoshop and it will also work on CS1, CS2, CS3, CS5, CS6 or CC.
What this action does is changing the red or green colors from your images and make some little adjustments to look better.
Any kind of question or issue you have to this actions please report it to me, I will answare of fix anything in no time. :)
