-meet w/clients before they book w/me
-do their engagement session if they've booked one
-2 weeks beforehand, either meet or do everything via phone or e-mail: get final balance due, shot list, schedule of day, directions or address
-sometimes I'll scout out the location, especially if I know it'll be tricky light, but that's not always possible
-print up my list of "To bring" the day before and get all my stuff together
-make sure all my CF cards are ready to go, charge camera batteries, figure out my outfit (how girly of me!)
-go to bed early
-day of: print up directions, shot list, schedule, make sure I eat enough to last awhile
-triple check list(s)
-load everything up and leave early
-show up early, do my thing then go home and relax &/or look at some images from the day
I do have a "master shot list" I made when I first started, but I don't need to look at it anymore because they're pretty obvious. Like I noted above, I do have a shot list from the couple, but that's for formals. I just start seeing things and shoot away.
