Ok, here's the deal...I use a Nikon Coolpix 4800 and it has given me tons of trouble.The Nikon people have been very uncooperative.
Some of you may have noticed that toward the top right side of my photos there are times a weird "little round thingie" appears. Sometimes it's gray, sometimes white, sometimes small and sometimes bigger. I do not know what causes this. Then when I crop the photo, it shows up the noise more. Does anyone know what this might be? Or will I be forced to take it to a photo shop to see about getting it repaired? I only see it on sky shots. Help? Anyone?
