The banner ends with the internal camera temperature displayed in degrees
Kelvin. This is intended for diagnostic purposes. The temperature is displayed
in degrees Kelvin so that there is no confusion that the temperature represents

to degrees Celsius subtract 273 from the value displayed.

7.4 JPEG Compression
There are 5 selectable levels of JPEG compression:
• Very High
(32 Kbytes Typical)
• High
(48 Kbytes Typical)
• Medium
(72 Kbytes Typical)
• Low
(100 Kbytes Typical)
• None (Lossless) 480 Kbytes Typical)
These are typical values with the time stamp enabled on the
image (640x504 pixels). The size of the images varies with the
image content. NOTE
Selecting None will produce the best quality JPEG files with Lossless
compression. Lossless compression does not introduce additional distortions
and every pixel is the same size as in the original image. Very High
