Leaving it late...
Years ago, it was normal to book a photographer a year or more in advance.
It does seem to be coming a thing where people are leaving it later and later to book.
I've been approached several times by people asking me if I can do their wedding for them - like next Saturday!
They then seem a bit surprised when I say I can't - I'm already booked!
Please, please, please - don't leave it too late to book a photographer!
