I've noted that in six places on these pictures, there are small clusters of bright pixels -- the placement is identical on all of them.
I've been back to check -- photos from December 31st exhibit the same symptom, but in fewer places, while photos from December 18th are clean.
I think the CCD is beginning to die.
It's an Olympus Brio Camedia D-230. It takes photos 1600x1200 in size. There's a digital zoom (which is crap), but no optical zoom. Pictures taken without flash (it uses a very slow shutter speed) tend to have a reddish tinge. I bought it, half price, on December 26th 2002 in PC World in Barnstaple. It's not done badly. It was my first camera, and I've learnt quite a lot in the interim.
There's a camera in the new PDA, but it's not terribly good, and I want a proper camera. I'm sure there are sales on ...
