I am shooting an abadonded house for the Georgia Preservation Society tomorrow and I have a couple of questions. First, when I bought my camera i also purchased a kingston 2GB card, and it keeps locking up. I am going to buy another 1GB card tomorrow morning before the shoot, are there any differences in card quality and if so which should i get? Also, i am using the shots for my ezine insidegeorgiahomes.com and there will be a story to go with it with links back to the historical society's site. I know i own the images, but how does it work with houses? Do i need them to sign something that says i can publish the pictures? Or do you only need release forms for people? The site isn't launching for a couple of months so i have some time if i need additional paperwork in order to proceed. Thanks!
