Sofortbild is a native Mac OS X application for tethered shooting using Nikon DSLR cameras.
Sofortbild allows you to control any Nikon D3x, D3, D700, D300, D200, D90, D80, D60, D40x and D40 remotely from your Mac via USB or through wired or wireless LAN using a wireless transmitter (on selected models).
Sofortbild offers you the possibility to trigger the image capture remotely, by simply clicking a button with your mouse: the image is instantly transferred to the computer, and you can review and analyze the picture, including the attached metadata.
Sofortbild transfers all captured images instantly to your hard disk for review in full resolution and quality and further image processing.
Sofortbild is great if you want to have more control over your shooting sessions, but can also help you capture HDR images by bracketing the exposure values.
