Regular and Long-Exposure Time-Lapse Parameters
The major dierence between Regular-Exposure Time-
Lapse mode and Long-Exposure Time-Lapse mode
is that, in the laer case, rotaon stops during the
exposure. This enables the sensor to capture more of
the available light resulng in a beer image.
The parameters for Regular-Exposure Time-Lapse
and Long-Exposure Time-Lapse are exactly the same
except for the Exposure parameter. In the Regular-
Exposure Time-Lapse screen you cannot change the
value for Exposure. It is xed at 0.5 seconds, which is a
requirement in order for SAM to provide an adequate
signal to control the shuer of your camera. Note:
This 0.5 second period is automacally taken into
consideraon when the App calculates the Video Time
Span parameter.
In the Long-Exposure Time-Lapse mode the Exposure
parameter controls the T
V
(exposure me) seng of
your camera and can be set to suit your needs. For night
scenes where a small aperture and low ISO value is used,
individual exposures may range from a second or two to
several minutes. Take some test shots to establish the
best sengs and exposure for your needs, then enter
that value into the Exposure parameter eld. Again, you
must set your shuer to BULB mode, otherwise the T
V
seng on your camera will take precedence over the
value in the Exposure eld.
The screen shot on Page 13 shows the various
parameters that you can set to create your me-lapse
video, with a few more that can be seen by scrolling
down (see page 14). All of the parameters are explained
in detail below. To start the me-lapse sequence just
press Run once all of your parameters have been set.
If you are parcularly happy with a set of parameters
you can save them in a prole and recall them again
whenever you like.
Keep it Simple to Start
The simplest way to get started is to set SAM up on
a tripod and take a stac Time-Lapse Video (one that
doesn’t involve panning). To do this, all you need to
know is the me span over which your video will be
taken and the length of your nal video.
For instance, if you want to get a me-lapse video of the
last hour leading to sunset, enter a value of 1 for Video
Time Span. If you want to compress that hour into a
45-second long video, set your Video Length to 45. It’s
that easy. SAM’s powerful app will calculate the other
necessary parameters for you.
