Hi Walter,
very good article :-)thank you.
Each layer is an adjustment. So Layer 1 might be your primary adjustment, Layer 2 a secondary, Layer 3 a mask, Layer 4 another secondary, Layer 5 an effect and so on
but i'd like to add something that you can add shape then outside the shape you can apply primary and inside it secondary and all play realtime and all in same layer...
Thanks
