Re: I have an engement shoot tomorrow..Any tips?
I would guess it is indoors, a small zoom and a flash would be my pick, bounce off the ceilings if possible (low enough) for even light. Don't be afraid to zoom in close. Get as many shots as possible to chose from later.
Make sure you have extra batteries for both camera and flash.
Good Luck, these shoots can be stressful but stay calm, help them relax, display confidence and never arrogance.
Good Luck!
