It would be helpful if you could include the following:
Date, venue and timings I’ll be needed for, along with a little bit about the event.
Date and timings (if known), number of people to be photographed and the type of images you are looking for. For example you could need 10 formal headshots, or a mixture of formal and informal portraits of your CEO.
Venue and date (if known), number of rooms to be photographed (to include exterior if needed), and approximate number of final photos required.
