White specks in images on SD550?

robscomputer

I recently purchased a SD550 and took the camera to a car show this weekend. After downloading the images I found that many pictures had white specks in the photos. It appears as random specks but they are very large.

Here's an example, see the upper left corner.



I had problems like this on my 10D before but that was with a very dirty filter. Checked the SD550 and did not find any dust on the lens, could this be interior dust? I can still send the camera back to B&H if it is so.

Thanks,
Rob

I wonder if that is a reflection from the spotlight off the car door. I suspect the reflection is off your lens and onto the inner surface of your filter.

And let me say "hubba hubba"!!:wow

I had the same issues on my Canon SD110. According to Canon, it is dust in the air, close to the flash that is illuminated by the flash and shows up in the photo. Somewhat a function of how close the flash is to the lens itsself. I tried to find this in the Canon info website and could not now, but remember having ths same issue and finding it there.

You can email support and they will send you this answer! In the interum, please post more photos ( not of the dust, but of the car show!)

The dust idea I would believe. The event was indoors and is used for lots of events, combined with weak air circulation I'm sure there was lots of small dust in the air.

Here's some more photos of the show. These came out fine, no visible dust.






I'm going to watch my photos more carefully for dust now.

C'mon! Dust? I would think there would have to be snowflake sized dust in the air to cause that. I still think it is a reflection off the inner surface of your filter. Notice how it appears opposite the hot spots off the car? Show us some of your other shots with these white specks. If it happens again, take your filter off and try again.

I'm not using any filter and did suspect it was caused by internal dust. I had similar problems on my 10D with a dirty UV filter, but that was major dust. I checked the front of my SD550 and can not see any visible speck of dust.

It's twue, it's twue.......lol

Small sensors, flash right on top of the lens and particulate in the air can cause this "snowflake" phenomena I've seen lots of pics like this, from many different compact cameras, and the cause is always the same. It can get even worse in a smoky enviornment.
