Well, Sat night was the night, and I managed to get some decent shots (I hope) the backdrop for most of them was less than ideal, but I was suprised by how good the lighting was. I almost didn't bother taking my 70-300mm as I thought it would be too dark, but in the end I used it more than the 17-55.
The 50mm f/1.8 was a welcome accompaniment, but would have been a lot more useful had it been AF. I shot with it mainly at f/2.5 and f/2.8 to give me a bit of a buffer if my MF was a bit off, Can't really tell if it worked until I download them from the camera, but hey. some of the practice shots in daylight below f/2.5 were OOF. my dodgy eyesight prob doesn't help!
The off-camera flash ability was a godsend. the pictures looked so much more professional. But when the other two "friends" that were there with their DSLRs figured it was optical slave, & driven by their own on-board flash, they were soon asking if they could "borrow it for a minute".
grrrr. couldn't say no really. (i'm nice like that)
I used the Nissin on my tripod (I don't have a light/flash stand) which worked really well, and tried as many different techniques as I could think of.
All-in-all I was fairly happy with how things went. I was quite nervous going into it. I can't imagine how you wedding togs felt the first time on your own! lol.
As for the scope for selling anything, well, I'm not sure that'll work out so well. one of the "friends" was the organisers brother. A photography student with an EOS 1D and managed to take 800+ shots throughout the day, which he's giving all away for free. but you never know. I got some business cards knocked up with the gallery address on and handed them to the girls and bands (not that the girls really had anywhere to hide them, if you know what I mean)
