After reading the many responses on this thread - some have hit it
right on the nose and helped me express what I have seen in ten or
more S100 and S110 powershots. Always with flash - random - almost
perfect circles - varying sizes from very small to dime size.
After four or five different cameras, it became clear that it was
inherent in the camera. I thought it was power related, but
thought it was power coupled with the jpg compression of the image.
After reading this later posts on this thread, I now believe it is,
as suggested, a reflection of the iris - and, since it only happens
with the flash, having to do with the speed of either the iris
opening or closing as affected by the drain on the power.
This is just my own humble speculation (MOHS) and I wouldn't want
to represent it as anything more than that, but it does meet my
empirical observations of at least six different powershots and
more than minimal time pondering the causes.
I have had very few shots that I could not correct in Adobe
Photoshop using the clone tool. With the new healing tool, the job
should be made that much easier.
Hope this adds to the emerging pool of information.
