Tim Pelling was kind enough to provide us with the information on this post. Thank you Tim ^^
My aging Canon 450D can only do 10 shot sequences and 3 exposure brackets.
Using my RPi, an Adafruit 16x2 (all purchased before I discovered ZeroOhm), GPhoto2 and a rechargeable USB battery I can now do timelapse up 1000 shots, and up to 13 shot brackets.
Additionally the RPi is running a web-interface (not shown) which allows me to review the captured photo’s on my iPad over WIFI.

Notes (if any)
USB Wifi Dongle
The version available from the RPi repositories is extremely out of date. Compiling a later version with Canon 450D support and resolving all dependencies would have been painful – fortunately as usual someone on the web already had the answer, a script that automated the process … but I lost the URL ;o)
To do list:
Run gphoto2 in commandline mode in a spawned process
Currently the minimum interval between shots is over a second and the http interface is very slow. This is because I am calling discrete gphoto2 commandlines for each action – which requires reinitializing the USB interface to the camera every time … slow. Running GPhoto2’s cmd interface (a bit like FTP) in a separate thread would speed things up and also allow me to avoid conflicts between the various functions.
