Why do koalas spend so much time sleeping? Koalas need to conserve as much energy as possible, as the energy value of their diet is low. Koalas generally sleep for about 16 to 18 hours a day. A common misconception is that they are âstonedâ after eating the eucalypt leaf. This is not so.

In digital photography, the image sensor format is the shape and size of the image sensor. The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular camera. In particular, image sensors in digital SLR cameras tend to be smaller than the 24 mm Ã 36 mm image area of full-frame 35 mm cameras, and therefore lead to a narrower angle of view. The size of a sensor is often expressed as optical format. Other measures are also used; see table of sensor formats and sizes below.
