Comment(by Quozl):

 The "dusty" effect is noise at low light levels.

 Tested two units on q3a15b in three different light levels.

 ||'''environment'''||'''horizontal illuminance'''||'''subject
 illuminance'''||'''image result'''||
 ||outside 10am bright sunlight||110000 lx||9000 lx||no noise detected||
 ||within 30cm of a window||1000 lx||300 lxno noise detected||
 ||within 3m of a window||676 lx||40 lx||noise detected||



 Yes, the image is dusty in low light conditions.  The test is not intended
 to compensate for In bright Australian sunlight the image has no
 observable noise.
