I am having trouble with white spots appearing on images taken with the
Canon 300SD. The FAQ's on Canon's Web site explain it this way:
http://alpha02.c-wss.com/inc/ApplS [...] 4&TRF=MAIN .
I don't think I buy their argument because taking a similar image at the
same time and place with a Nikon 990 or Nikon 5700, spots don't appear. If
anyone else is having this problem I would appreciate your explanation and
your solution

A common cause is dust in front of the camera when using flash. Can you
post a sample to a Web page somewhere?

This link http://class.aggienetwork.com/clas [...] y-test.htm should
have a test image with three white spots noted. I will appreciate your
evaluation.

Almost certainly very small flecks of dust (or perhaps smoke) near the
lens, which get illuminated by the flash, and appear as out-of-focus
blobs.

The visibility will be dependant on the axial distance between the flash
and the lens, and the depth of field. With a point and shoot camera, the
very small lens focal length means that the depth of field is very great.
The small distance between the flash and the lens means that the particles
are very brightly illuminated. Thus the flecks, rather than just creating
a general hazy atmosphere, actually appear as out-of-focus blobs.

Cheers,
David
