An enjoyable and interesting evening looking at Irene's holiday snaps; as she put it...
I knew just the image I wanted to try some of her techniques on. After 2 hours fiddling and diddling with 2 different opacity, masked white layers - blend softlight, 3 Gausian blur layers - blend multiply, levels adjustments and an orange layer to warm it up; maybe I am getting somewhere. Attached are the before and after images, perhaps I should book on her course!
FWIW here's my attempt at adding a White Layer
