TIPPING...I NEED HELP, Getting hitched in 10 days

know its long but need the help
OK getting married in 10 days, and FH is freaking about the tipping situation. Who gets what, what is standard? A general idea.
At the moment we are concerned with photographer, he made it clear to tip his guys accordlingly. What does that mean. He said he is not charging us the 1 hour over time, so make sure we 'do the right thing'
What are we talking here
I have reg. photog
photojournalist/zap shot
videographer
lighting assistant

Our package is costing 6800, we got thr top package

Please help, thanks

I just read this somewhere
The typical tip for those in the food & beverage serving
capacity is 15-20% of the total charge for their category.
