Halfbake

I know this question was answered by MEB but I still struggled with what I feel should have been a very simple adjustment, I just wanted to darken the sky and lighten the beach for example but the YouTube tutorial is for the pc version and I spent hours trying to figure this out so for anyone else still scratching their head this is what I have found by trial and error works for me. Objective to darken sky and lighten beach 1.Add new fill Layer Picture>Layers Studio> + >New fill layer Now have blank grey screen 2.Select Gradient tool and drag from top down. 3.Layer Studio> ... > Change blend mode from Normal to Overlay Should now see picture again 4.Colour Studio>Grey Sliders 5.Select/highlight top node/circle of Gradient line and change grey slider down to darken the top of picture/sky. 6.Select bottom node/circle and change slider up to make bottom of picture/beach lighter Done
