In this tutorial, we learn how to create a Lomo effect in Photoshop. This is a contrast that gives the photo a "cool" vibe and change up the effect that you see. First, load up your picture into Photoshop and then go to adjustments, then curve. From here, add a slight s-curve and then add a green channel with the same s-curve that you just created. Go to the blue channel and create the opposite s-channel from the others, then click "ok". Now, go to layer, new adjustment layer, then gradient map. Go to the pallet and set it as overlay and reduce the opacity on the photo. Now save your photo and you have a great lomo effect!
