To take a bulb exposure first set the camera shutter speed to "bulb". Then either press the "Release" button to start the exposure and again to end it or select the "Time-lapse/bulb shooting..." option from the Camera menu.


It is not possible to use bulb mode with older cameras when triggering the shutter release from the PC. This is a limitation of the camera not DSLR Remote Pro for Windows. Pictures can still be taken in bulb mode by pressing the camera's shutter release button.


Mirror lockup can be used with all cameras that support mirror lockup if the picture is taken by pressing the camera's shutter release or by using a remote release cable. Some older cameras (e.g. Canon EOS 10D) can use mirror lockup and be triggered from the PC. With these cameras the mirror will flip up and the picture will be taken after a 2 second delay.


Canon EOS 50D, Canon EOS 7D, Canon EOS 5D Mark II and later models:
Pictures can be taken from the PC with mirror lockup enabled by pressing the shutter release button which is located in the main window below the histogram display.
