I'm speaking about hazy images:

I think i can reproduze this. Go into a dark room, put on the light. Make a photo so that between you and the object to photograph is the light of the ceiling.

For me it seems that light to the N900 reflects in the chrome ring.

So the haze comes more if flash is used because flash is used if you don't have the sun as light source. But the haze can also come without flash if sun light reflects on the chrome ring.

Sure, i'm puzzled...
