The problem with wedding photography is always time, there is never enough! I have faced this situation on many occasions, and generally find people really happy to oblige,being a wedding and all. On one occasion, a couple wanted a shot on a jetty at sunset but there was a single man fishing at the end, I very politely asked if he could move for just a couple of minutes. His reply was, after seeing the couple, I will move if you give me $50.00!
I told him to forget it and went back to the couple with the news. Just happened at this wedding the groom was a front row forward for the Manly rugby league team, as were the groomsmen.....long story short....they had a fruitful discussion and the money hungry gent decided that this spot was no good for fishing anyway!
