These dots were there before GEM. GEM removed all these dots and images became 
smooth; along with the 
dots went the subtle details too. When I say details, I mean, snow had small 
dark patches caused by shade
and some of such deatils were lost.

I have another doubt related to this,
Does "Anolog Gain" & Brightness setting are same?

Thanks
