Tipping etiquette

Instead of asking the brides, how about I ask you.

I have no idea what the etiquette is. Can you help??


I have a:
Photographer
Assistant
Photojournalist
Video person

I also have:
MC
DJ
Lighting person/assistant

I don't want to break the bank, but I don't want to be cheap either. I want to know what's fair!


Thanks
