I tend to do my salmon in a foil parcel in the oven - so steamed, effectively. If I want the fish cold, I'll just let it cool in the parcel, and it stays lovely and moist.
Skin on filets in a non stick frying pan.
Touch of oil.
Skin down till almost cooked through and skin well crisped: 5 min?
Turn, for 1 min
