| HFOV* | - short for "Horizontal Field of View".
The horizontal angle in degrees that a particular image represents of
the world. The wider a lens the greater the angle of view. When using
a 35mm camera the HFOV is calculable from the focal length as follows:
if camera is used portrait HFOV = 2 * tan-1(12 / focal_length) if camera is used landscapeHFOV = 2 * tan-1(18 / focal_length) (Don't be frightened of these calculations you won't need them to create a basic panoramic image-TM) |

| JPEG | - Joint Photographic Experts Group - a technology

which can be altered to take up less storage space. Some quality is sacrificed in order to get a higher rate of compression. JPEG images are good for photo quality. |
| Megapixel | - one thousand pixels |
| Meta files | - graphics that contain both vectors and bitmap data. |
