Dont know if this is the right place to post this, moderators please help move to another place if its incorrect
I just noticed this thing after trying out some long exposure shots.
There are blackish spots in my images, round in shape, fixed in places....
Pic1 (around and above the left most lamp post just after the bridge)
Pic2(mostly around the left lower side of picture where its brighter)
What are these spots ??? Do I need to do anything to get rid of them ??
Having said that, I havent made them reappear by shooting my usual subjects (flowers)
Thanks in advance for the advice !!
