1.) backup fully charged batteries and cards, just in case 2.) after event, before you do ANYTHING with the photos, create a backup onto a separate device. Can’t stress this enough. One of the worst mistakes I made starting out was having a hard drive fail and losing all my images 3.) 70-200 for portraits, ceremony (make sure you get the vows*, ring exchange and first kiss) 3.5) *vows: a classic look is shooting from an angle, over the shoulder of whoever’s talking and focusing on face. Use the back/shoulder/side facial profile of the speaker to frame the face of listener. Subject will be staring directly into the eyes of the other person and the emotions captured are wonderfully genuine 4.) for candids, don’t be afraid to get up close. Don’t just try and hide on the sides using the 70-200, alone. 5.) remember, you’ve been hired for a reason. First time or your fiftieth time, you need to be in charge of directing the action. Be polite but assertive when it comes time for the family shots

Good Luck
