A couple things -- I kind of wish the actual photog was here to explain what actually happened. I can say on a few weddings I have second shot, I have missed shots --- why? Because I was not allowed to shoot on my own cards and one of theres took 2 shots then read full. I had the pouch in my pocket so i quickly shifted cards but the moment got lost. they weren't huge cards either, 1 8GB and 4 4 GB.. Later in the day I reformated the card and things it worked fine, but still --- sometimes there are errors.
I am just saying its real easy to throw the photog under the bus when he/she isn't here. Even easier seeing as though we have not seen these pics that saved the wedding!
Other things too ---
2 weddings ago my second shooter had a rented lens - this lens worked fine but at times the camera would error out saying ---the lens contacts were dirty or just overused ---either way, through the night she had to take the lens off and put it back on again several times. Just saying, lots can happen and this photog isn't here to defend him/herself - we don't know what went down and why it went down.
With that said though, really not sure why this tog didn't have a pouch of cards on him (ok, I can think of 1 reason --- if he had one of the card holders that closed via velcro, I would not want to be that guy making that velcro tearing noise at any point of the ceremony!)
To those who said just delete a few and switch to smaller file size...that isn't something you can do as the bride is coming down the aisle. That's for the tail end, after snapping a few thousand dancing shots, but the B&G are still going off on the dance floor and you've fill all the other cards already ---thats when you delete and switch file sizes (I always shoot in mRAW at weddings, full size RAW is overkill I think for anything but the formals). If your in that place, your only solution is to run run run (or, as someone else mentioned, this tog had 2 bodies, couldn't he have used the classic? Or, just snagged the lens from the classic and put it on the mk2? I think thats the biggest reason I wish this tog was here, because he/she had a solution ---hell that's why we have backup second bodies right? that didn't get used. Or even easier ---why not just use the card from the classic? Pretty easy and quick to make that switch. So yeah, I have to wonder if there was some other problem that his this togs camera had, and when asked about it is was just easier to say ran out of memory than to explain error messages..
And finally, lets see these shots that 'saved the day.' We're throwing this other tog under the bus based on a fishy excuse and the claim of day saving images that we haven't seen!!!!!
EDIT --- if your shots are good, and this guy did totally miss that ---instead of bragging here ---contact the tog and offer to sell him the shots!!!!
