Shooting Guide
The ThumbCam has a fixed lens (a vari-focal lens would, simply, not fit) – so the
size of subjects in your shots depends only on how close to the subject you hold
the camera.
•
Typically, about 3 feet (1m) is about right if filming a shot of someone's face –
this way, their face will occupy approximate half the vertical space in frame.
•
To get a whole person in frame (assuming they're approximately six feet tall)
then you'll need to be about 10ft (3m) away from them.
ThumbCam has a fixed focus lens, which means you'll never need to

•
The wide angled fixed lens will achieve focus within approximately 30cm (1½
ft) from the lens, varying slightly depending on the amount of available light.
It will hold focus to infinity.
•
Basically, keep everything more than two feet from the lens, and you'll have
no worries!
The ThumbCam will adjust exposure automatically, varying its gain setting
autonomously, reacting to the amount of available light. There are a couple of
things to bear in mind, however:
•
Shooting a dark subject in front of a bright background can cause the auto-
exposure feature of the ThumbCam to become confused, and drop the
exposure down so that the background is correctly exposed whilst the subject
becomes a silhouette. Avoid brightly lit backgrounds, unless you want this
effect.
•
To decrease exposure, the
thus exposing each frame for a shorter time. This means that you'll get better
high-speed photographic performance in bright light – useful for shooting fast
events, like sports.
•
On the other hand, in low-light, each frame needs to be exposed longer to get
enough light into the (very small) lens. This can be effect can be minor (such as
shooting in a shopping mall or a stadium under lights) or particularly serious
(in situations such as shooting under a street lamp).
•
The image quality, depth of field and exposure range will all improve
dramatically as more light is available.
Tips & Tricks: Photography is an art - there is no right or wrong way to shoot.
Practise really does make perfect - or, at least, better. The best way to get better
results is just to keep using the ThumbCam. Besides, it's not like you'll be wasting
film; just clean off the microSD card now and then, and you'll be set!
