Interesting possibilities
The combination of the iPhone and the Camera+ app allowed us to
get ISO sensitivity down to 0.01, which in turn allowed us to achieve
shutter speeds of about four seconds in broad daylight. This suddenly
opened up the possibilities of daytime long-exposure shots or control
of light trails in low light and night time photography. Another nice
feature, that was of great help, was the ability to set a focus point in
a shot by tapping on the screen in the appropriate area and then
adding a second point that could be used to meter the light. Moving
the metering reticule around the display meant we could choose
which area in the scene the camera was going to meter. We tried this
feature out at a local beach. Placing it just above the horizon gave us
a good balanced exposure. Pressing the button started the four-
second exposure and the sea was transformed into the familiar misty
fog made popular in DSLR photography.
Some examples of the long exposure
capability of the iPhone, coupled with the
Camera+ app. It is quite impressive to be
able to set an ISO of 0.01, to give you a
chance to shoot 3 second exposures on a
bright sunny day.
