DSLR Shutter


DSLR Shutter is designed to be a simple tool to capture long-exposure images from digital SLR cameras using their "bulb" setting. It allows you to specify the number of frames, their duration, and various delays to act as a software interval timer for your camera. It is a cross-platform application with both Windows and OS X versions (Universal Binary for 10.4 and 10.5 - may work in 10.3.9), supporting both the ShoeString Astronomy DSUSB adapter, serial port, and parallel port triggering (parallel port on Windows only).


Best of all, DSLR Shutter is distributed here as freeware (and will stay as such). If you use DSLR Shutter, enjoy it, and wish to make a donation to help support it, its development, and the development of similar products, you can use the button below. All donations are greatly appreciated.
