White pixels on a dark image

Hi All

Please excuse me if this sounds obvious. I tried searching the site
beforehand for similar answers.

Am a film SLR user who just bought a pocket sized digital.

All seems well in the past few days but now my images aren't looking
so good. A snow-like flurry of white/yellow pixels are showing up in
the dark areas of my digital images. Using a Pentax Optio S30. Hadn't
noticed it before but have only had the camera a week. Not sure if
it's software (ACDSee, supplied with camera) or hardware.

Please advise.

Paul

Using a flash? sometimes dust in the air can cause something like
that.

Welcome to the world of compact digicams, where depth of field is huge and
dust is a problem with flash photography. My suggestion is to clean your
house.

Without seeing an example and going from the description, it sounds
like you're seeing dust in the air that's illuminated by the flash.
This is a comon problem with some smaller digital cameras because the
flash is so close to the lens, and the depth of field is so great
(things close to the camera lens are more in focus than in film
cameras) that dust motes are being illuminated, and seen by the sensor
as white blobs.
The solution is to move the flash further from the lens; in your case,
this would mean using an accessory flash. Otherwise, it's a frequent
thing inside houses with dusty air.
