Step 4

Select Image > Adjustment > Photo Filter. Then choose the ‘Cool Filter (80)’ and change the density to 30%. You can experiment with the various filters and densities if you wish.



You should now have a bluer looking sky. If you compare the original with new looking sky, you will notice a drastic colour different.
