remember the larger the frame size and the greater the quality equals much larger
image file sizes. Something to think about and consider before you shoot.

Many cameras have power saving features which will power down the camera after a
length of time if no buttons are pushed. In many cameras you have the ability to
change this length of time and in many cases shut this feature OFF completely.
Basically you don't want the Pclix LT interval to be longer than the power saving setting
of your camera.

Many cameras require that you turn on the Infrared Remote function when you want to
trigger the cameras remotely. Also check to see if your camera will disable this feature
if after a certain length of time if the camera does not receive a trigger. The Nikon D70s
for example can be set to a maximum of 15 minutes, the Infrared Remote feature is
automatically switched off by the camera if no signal is received in that time. However
if this same camera is powered from the Nikon Adapter instead of the internal batteries
that Infrared Remote function is NOT shut off automatically. Other cameras function
slightly differently so ensure you understand the settings of your camera in the remote
mode.
Time-Lapse Shooting Equation:
One question that comes up quite often is "What is the best interval to use in a certain
shooting situation?" Good question indeed. The answer to that question is like asking "How
long is a piece of string?" However, there are a few quick ways to get you in the ballpark plus
a few variables that can be added in order to get a bit more creative.
Here is a basic (some would say not so basic) equation to help determine the best
interval between shots. This is only a starting point, obviously many combinations of shooting
lengths, interval settings, frame rates and other factors can come into play. However as you
get more comfortable with the process this will become easier to understand and you well
then be able to focus more on the creative aspect of time-lapse photography.
Equation – Obtain Shooting Interval
Let's say for example you are going to photograph a sunset and you imagine your
shooting time will be about two hours. You first need to convert that two hours into minutes
which gives you 120 minutes. But what we really need is the total number of seconds in that
original 2 hours, so take the 120 minutes and multiply that by 60 seconds. You end up with
7200 total seconds.
(2 hours multiplied by 60 minutes multiplied by 60 seconds) = 7200 total seconds
Now lets say you would like the length of your finished sequence to be 10 seconds, you
must first multiply 10 seconds by either 24, 25 or 30 frames (or images) per second. Typically
standard video has 30 frames per second in North America and 25 frames per seconds in
Europe. Whereas film and High Definition Video generally have 24 frames per second. Lets
assume we would like 30 frames per seconds because our time-lapse sequence will eventually
be shown on television in North America. So we use the equation below...
10 seconds multiplied by 30 frames per second = 300 frames for our finished sequence
