I was asked by a friend earlier this summer to help as a second shooter for a weeding she was doing. I wouldn't be paid much, just enough to cover the few hours I was going to help out...that was fine by me, I was really just doing it to help out a friend, since I mostly just shoot landscapes or my family. The original intention was for me to head out where the guys were getting ready (a few miles from the church) and focus on them for about 30 minutes prior to them arriving at the church. When I spoke with my friend, she asked if I had a spare step stool that I could bring along so that we could set it up in the back corners of the church (to help get above the people in the pews)...Not a problem, I'll swing by on my way out to see the guys, and to check in with you before going on to their place. I was ready, I had both my EM1 (with HLD7) and 4 batteries, along with my EPM2 and 3 batteries. I had intended to shoot mostly with the 12-40 for the procession, and then switch over to the 75 during the ceremony. I also had my FL-600 which I wasn't allowed to use during the ceremony (pastor rules), and my 7.5 and 25 (the 25 was mounted to the EPM2). I arrived early at the church, only to find that just a few minutes prior to that, the main photographer just threw out her back. As she was being attended to on the floor, she looked up at me and asked if I was ready to be the prime. I think I nearly passed out...Luckily, she had the night before, a friend wanting to shadow/assist her with this wedding. She got to take over all of the main photographers gear (Canon 5d3 and a few lenses), and between the two of us we rocked out the whole wedding (reception and all). The weather of course didn't cooperate (pouring rain), so most of everything had to be taken indoors, except a series of these shots to go along with the theme of the wedding...Baseball. Moral of the story...always be prepared, as Murphy's Law will always prevail...in the end, despite pushing the EM1 to iso 6400 in a lot of instances, everything turned out better than expected, and all parties (bride/groom, and main photographer) were happy with the results. Anyhow, I'll be doing this again in two weeks, hoping to just play the 2nd shooter role though ;-) For those that do this for a living, my hat's off to you!
