Question about Sony Cyber-Shot DSC-S70 Digital Camera
Hi, For the last 3 days, I have tried my new Sony S-70. Last night, while reviewing the photos in Photoshop, I remarked that 4 very subtil round dots of 15 pixels in diameter where present at the same exact locations on some of the 640 X 480 snapshots taken previously. To verify, I made a test by photographying a white sheet. On the neutral grey result, the dots were present at the exact same locations. I repeated the test, the same...The dots are just a little darker than the adjacent color(s). On a 100% scale I would put it, at the very most, depending of the situation, to be 1% darker. When to colors are very bright, I don't see the dots but...is this normal? I am new to digital camera but not new to photography and Photoshop. Could it be a problem with de CCD chip? Should I return the camera? I am surprised, this is such a splendid tool. Any advice will be welcomed. Fran?ois

Tiny dust particles on the lens can show up like this. You may not even be able to see them by looking at the lens itself. Try giving the lens a good cleaning with a Lenspen (Which you can pick up at any camera store) before taking it back. SInce the spots show up in the same locations it would argue for some fixed specs somewhere. Dead pixels usually show up as points of color instead of diffuse dark patches but a dust particle (out of focus) can do that. We know that you can see strange "flying Saucers" when there is dust in the air and you use the flash.

Francois, First make sure you ddin't buy a Nikon 990...once that's confirmed, take your S70 back! It sounds like you did all the correct tests to verify the pixels. I also did the test and my S70 passed with flying non-colors. If you 've only had it for a couple of days exchange the thing for a brand new one. Prove your point and have a photo ready of the dead pixels. good luck!
