Default Whats up with my pics P72?

Hiya,

Have just purchased a brand new Sony Cyber-Shot DSC-P72 and have been taking pictures for a couple of days and was very pleased with the results.

Last night I went to a friends gig and I thought it would give me a chance to get some pics of the band and see how the camera operates in a club lit environment, which in future is where I will be taking a lot of my shots.

Anyway when I got home I was looking through the pics and I noticed that some of them had these white blemishes all over them, they kinda look like mirror ball light dots, but as there was no mirror ball at the club I started to worry.

Can anyone tell me what is wrong? I was playing around with lots of things in program mode while shooting as it appears on some pics and not others and just wondered if it was a camera fault or a known problem/feature etc.

Here is one pic without the blemishes:

And here is the next one with blemishes

http://www.disfunctional.fsnet.co.uk...s/DSC00181.JPG

And another totally away from the lights shot with blemishes

http://www.disfunctional.fsnet.co.uk...s/DSC00220.JPG

Can anyone help me or tell me what these are? Also any suggestions for the best settings to use in places like these?

Any help would be much appreciated, thanks

These "blemishes" is caused by the light reflections in your lens. It's mostly caused by the angle between the lightsource and the lens glass. The only thing to do is to find another locations to shoot from.

They might also be dust particles hanging in the air close to the camera, that become visible because of the increased depth of field of digital cameras compared to film cameras, where they are so blurred you don't see them.

No kidding, I read that in an article in german computer magazine c't. They even shook out a carpet and then took pictures (with flash) to demonstrate the effect. It looked very much like the pics posted.

I forgot to mention, that this happens when using flashlight. The dust particles get lit up by the flash and judging by the hard shadows in the 'blemished' pics, he was using a flash.

I dug out the article in the meantime. They said, it happens mostly with compact cameras, where the flash is close to the lens. The dust particles are quite close to the lens too and as I said, a film camera (or a digital SLR with a large sensor) wouldn't show it because it has less depth of field.

ahhh so it isn't my camera thank god

Yeah I was using the flash quite a lot and was getting really blurry, unclear pictures so I started mucking around with all the settings just to see what they would do and if i could get rid of it / better quality etc

Can anyone possibly tell me what the best settings would be to use on the DSC-P72 for taking pictures of gigs etc?

I really dont want all them blemishes back, but I need to really use a flash in the dark, it's just ive never seen them in any pics before so was a little worried.

Thanks for the replies by the way
