A Trigger image needs to be:
a JPEG or PNG file
less than 500,000 pixels (in total - width x height) when uploaded to the Aurasma Studio.

A good Trigger image means the Aura will
activate smoothly and the Overlays will track
Qualities for good Trigger images are:
tonal variation and contrast
unique shapes and forms
lots of detail across the entire image
for ‘Location Auras’ (Trigger images of real
world locations): flat surfaces, square on,
photo taken in neutral light.

Masking gives you the ability to ignore some areas and features from a Trigger image. Masked areas
are not used for recognition. You should first test the quality of the Trigger image without adding any
masking as sometimes you can actually make tracking worse.
Features you may wish to mask:
large areas with no features
text (regular text - sometimes chunky and unique text can help improve a Trigger image)
shared features that may appear on your other Triggers (logos)
repeated features and patterns.
logos and especially the Aurasma logo and Call To Action
The masking buttons can be found under your Trigger image when viewing it in the Aurasma Studio. To
use masking, just click on one of the buttons, and drag your mouse over the area(s) you wish to cover.

The Graphics Interchange Format (better known by its acronym GIF; /ˈɪf/ or /ˈɡɪf/) is a bitmap image format that was introduced by CompuServe in 1987[1[[http://en.wikipedia.org/wiki/Graphics_Interchange_Format#cite_note-87aSpec-1|]]] and has since come into widespread usage on the World Wide Web due to its wide support and portability.
The format supports up to 8 bits per pixel for each image, allowing a single image to reference its own palette of up to 256 different colors chosen from the 24-bit RGB color space. It also supports animations and allows a separate palette of up to 256 colors for each frame. These palette limitations make the GIF format unsuitable for reproducing color photographs and other images with continuous color, but it is well-suited for simpler images such as graphics or logos with solid areas of color.
