Thank you CT and Les.....i'm only doing it so i can see a building project commence and then animate it...so the less money the better really as its just a project on a whim..
If thats the case you want to do it every hour. My entry to Uni was a time elapsed sequence of the same subject, though I did it using a borrowed Nikon F6, a timer and a bucket load of cheapo Kodak 200 film over the space of 7 days. I planned the shoot with a local contractor. They provided a secure, untouched location for me to mount the camera. I was quite lucky in the end as they commissioned the final product which paid for the bucket load of film and partial tuition fees.
Remember, when you sample the photographs together there will be either 25 or 12.5 (double the length each image is displayed on screen, which in turn interpolates to 25) frames for every second (fps) of animation. For the moving image to work you are going to need at least 25 seconds (thats 625 captured images at 25fps or 312.5 captured images at 12.5fps).
Now you need to plan your composition, exposure set up, developing method (best shooting jpeg to minimize post production), camera placement, you will need a tripod, secure location (if not out your window).
Well, what I am trying say is, BE PREPARED, BE PATIENT.
Good Luck.
EDIT: I majored in Computer Animation (CGI) so if you need any help with that drop me PM.
