Cindy, i have to admit that most of my ideas are possible because i have a small dinner by local standards..only 10 tables.
With regards to table shoots, i only had them after my second march-in. Meaning after the first march-in, we were able to sit down and enjoy our dinner (for a bit;-) and then we went around to the tables, purely for chit-chat. At this point, the photographer did not follow us. After the second march-in and after our little friend has performed, we did another tour, and this time, the photographer went with us for the formal shots.
I am not against table shoots per se so my photographer would put the journalistic pictures first when he lays out the album and the tables shoots come last.
What you could do is to assign a child to take pictures; our little friend took some pictures for us; very very cute perspective. I saw some threads about leaving disposable cameras on the table and i dun think that works. If u want posed pictures, u are better off getting your photographer to take them!
