Carol, he did say it was women's hockey, and us men are not like you women....
Hey, I'm a hockey goalkeeper.... and believe you me, some girls can really hit it ****dy hard. Won't go into detail but if a ball misses the padding it can flippin hurt LOL.
Some ideas for shots:
At penalty corners (also called short corners) - side on to goal so you capture the defenders looking in your direction waiting for it to be taken (so position yourself at the other side to the attacking forward say looking straight down the back line or somewhere around the 'long corner' marker). If a defender is stood on the inside of the post they may appear to be peeping around it.
If you stand on the side line, also look at the player who actually 'pushes' the ball out. They will place the ball on the back line, lunge forward (often with their foot pointing in the direction of the player who will receive the ball so that may also give you a clue as to who is going to receive it if it is not obvious), position their stick behind the ball, look to where they're pushing it to and then 'push' or hit it out. Often pushed for more accuracy.
Also at shorts, if an attacking forward is knelt down at the top of the 'D' with their stick along the ground, they will usually stop the ball for another attacker to take a straight strike or 'slip' it elsewhere.
If you want tight shots of the end of the stick and the ball then get to ground level for a closer to the action shot. I would take most shots from kneeling level or below anyway. Standing, especially if you are taller than the girls, in my opinion, will not as good results wise.
A lot of teams have their half time talk inside the goals. Some pitches are heavily sprayed with water (usually National League level) or are just very wet obviously following rain. If you shoot tight then you could capture some of the spray.
Have fun. It is a fast sport so keep one eye on the game (as well as concentrating on the shots) so you don't get hit or get in either the umpire or a players way - both can be running off the pitch.
PS - Also, check out of courtesy from both captains that they do not object to you taking photos.
