I love the idea of live pics and texting.
Can ANYONE add pictures to the slide show, or just the photog?
Also, in your honest opinion, is it really possible to do these WELL, without another person on staff?
I have enough trouble concentrating on the music, then add lighting (something MORE than just sound-active)...
and at that point, there is no way I could ALSO be screening texts and fiddling with pics.
It's easy. Once you get into the rhythm, it's not a problem at all. Start a song, pickup the camera, click-click-click. I have people send me cell phone shots, but (for whatever reason) I don't put them into the slideshow. Also, no, guests cannot add either pics or messages to the screen without it going thru the DJ (or person handlin live-pics). That is a recipe for disaster. I regularly get seriously inappropriate crap from guests.
