As I mentioned earlier, the second preset I shared on Keri-Anne's site earlier this month was this Photoshop action that pretty much resembles the Instagram filter, Valencia. It is my favorite filter ever so I was inspired to achieve the effects on Photoshop. It isn't exact but it certainly enhances the overall image with better contrast and color balance. Works well on all sorts of pictures! Tips: the color balance layer's opacity can be adjusted as desired.
Have a lovely day and comment below if you have queries!
