After taking some photos outside at Aperture F/32, I notice couple of black dots on those photos..
Are they most likely be dust spots or dead pixels ?
Attached is a sample of the dots..

If they are just dust spots, any one knows how long will it take for me to get them cleaned off at canon service centre ? Do I have to leave my camera there and collect it a few days later ? How abt if they are dead pixels, will canon do something about it if it is still under warranty ? Thanks a lot !
