Others have had this idea, and I have had something similar hanging out in the back of my brain. People were yammering about it this evening, so I'll repeat it here so nobody forgets.
We will have a professional photographer at the wedding and reception. Said professional photographer will take the traditional set of posed photos, and may even take some candids here and there. We will probably pay a good sum of money for their services.
The rest of you guests will probably want to bring cameras so you can take your own photographs. This is fine and dandy, and in fact, highly encouraged. Those of you with digital cameras should be prepared to share these photographs with the lucky couple on the day of the event.
How will we make this possible? We will likely have a laptop there with some sort of connectivity device(s) that will gladly read files off of whatever digital media your camera uses. We will probably ask you to give us copies of your photos before you depart. Hopefully we'll find an idiot-proof way of doing this. Well, perhaps I shouldn't say that, since nature is very good at inventing better idiots. But we'll try our best to get as many pictures as possible.
If you know a good photographer, please let us know. Referrals are probably worth a lot here. And as much as I know that my own mother is a talented photographer, she will have other things to do that day, what with being mother of the groom and all. But she will take many pictures, as she often does. And she is not exempt from our sharing idea.
Oh, by the way, Mom, please try to take candids as opposed to posed shots. We'll have enough posed shots already. Explore the candids. Remember that lions and leopards and other such animals don't pose for camera-wielding humans; wedding guests are almost as wild.
