Just took my new SD1100is for a time lapse try out but I ony think I shot a test since I can not open it (if it was shot!) On my memory chip the are to things being stored one is called MVI 0029 THM (it is 9.88 kb) and the other is M0100 CTG (it is 178 Bytes). It was a windy and nippy by the Brooklyn Bridge so I only shot for about 12 minutes.
Prior to buying the Canon SD1100is I have been shooting a Panasonic and Kodak digital camera. I find this Canon to be a bit confusing when it comes to navigatiing the menue and all its setting possibilites. I have small hands but this camera is like handling a small bar of wet soap! I am glad it has a wrist strap!!
