PalmDSLR is a "freeware " which lets you control your Canon DSLR camera from your palm. It has been design for the management of Astronomy Photo but it could be used in any other situation where a timer is required to take series of photos. At last PalmDSLR allows you to record all the caracteristics of your shots to be able later to formalize your works. PalmDSLR has been designed keeping end-users concerns in mind:
Portability to let your heavy stuff focused on your camera and lens not on your laptop computer,
Compatibility with older palm (at least PalmOS 3.5) to be able to create cheap and more powerfull alternative than Canon cables,
Efficient design:one screen to centralize everything, no setup required.
