Many wedding photographers have time limits on the day of the wedding. You pay for 4 (or more, or less) hours and then have surcharges to pay is you wish the photographer to stay longer. I have a whole different perspective, I am available all day from the wedding preparations in the morning to capturing the fan and energy at the wedding reception.
It is up to you to use as much of my time, or as little, deeding and what ‘you’ want to and not be dependent on my time.
No additional fees for my time during the wedding day.
