I do not give discounts for a shorter amount of time as I only accept one wedding/event per day. Even if your event only takes 3 hours between the travelling to get there and back there is no way that I would ever do more than one wedding in a day. I believe in quality not quantity. Fortunately, I am very busy and have many requests. Unfortunately many of these requests are for the same day and so seeing as I work alone and always photograph every wedding myself I can only accept one wedding per day. It would not be very good business practice for me to give a discount for a shorter job and then receive a request for a big wedding where I could have earned my full fee.
