At the former Vinces Gym (Ventura Blvd) most all the BB'ers there did that form of laterial raise like Trowbridge suggested. The little finger held high and the thumbs almost pointing straight down, slight bend in the elbow. You kepted the DB directly in line with the body and started the lift with the DB resting against the leg, not in front of the leg . They also did a form of 'W' DB seated presses, which Larry Scott favored, if I remember correctly. Members of that gym were pretty well known for their delt development and also the pec/delt tie in. Don Hollworth (spelled wrong) comes to mind as having the widest and better developed delts at that time.
One arm laterial raises, either leaning against a wall or lying on a incline or flat bench can target the laterial delt head also. Pressing a DB (usually light weight or one with-in your capacity) ) over head and lowering it slowly to the side, like a negative laterial raise, can affect the laterial head strongly. Good Luck.
