I shot a wedding in May (which I normally avoid).
It was the 'worst case' of a family friend situation with people on a very tight budget... i.e. free.
It was interstate and they did pay our expenses (Nel was with me), so I still got more than this $100 dude (i.e. a paid trip to Melbourne).
I had 2 camera bodies, several lenses, umbrellas, stands, remotes, 3 flashes etc.
Nel did all the posing and directing.
We dumped images to a notebook during the day, and onto a external hard drive at the end of the day.
Etc. I.e. I did the most professional job I could.
Prior to the event when they asked us, I did sit them down and explain what my capabilities were, what a pro-wedding tog would do that I could not etc.
In other words there was a clear explanation of expected outcomes.
The photography was our wedding present. In the end a very happy couple.
It's a situation, although I was happy to do it in this case, is not something I'd make a habit of.
The alternate for this would have been a bunch of friends with P&S cameras, so no 'pro-togs' missed out
I wonder how often this sort of situation occurs?
