The booking fee was £8 last time, if this changes I’ll update here.
You will then be given back your booking fee as a credit towards any prints or digital images that you wish to buy.
In the event that you don’t use your booking credit it is not refundable. In the event you do not show up or cancel it is not refundable, as I am unlikely to be able to fill the slot at the last minute…when you book though your booking confirmation does allow you to reschedule (assuming there are any slots left).
