The Press & Lock mode is designed for long exposures. If you do not want to keep
your finger on the screen all the time, you can use this mode. The shutter will open
with a touch on the button and it will stay open until the next touch. When you
touch the button, a counter will start at the bottom of the screen. The camera
must be in BULB mode to have flexible exposure.
9.1.d. Timed Release:
The Timed Release mode is the perfect solution if you want to control the shutter
with great precision. This mode has a single parameter:
Exposure: This parameter controls the exposure in hours, minutes, seconds and
milliseconds. In order to change the parameter, touch the exposure value and a
numeric keypad will appear. You can type in the desired exposure value and then
touch anywhere outside of the circle. The new exposure value will be shown in the
circle. Touch the notch on top of the circle and then pull the curtain down. You
can start the exposure by touching the orange button again.
