Need you guys to help me identify this problem..
Check out this two pics..
Notice inside the two grey lines which i added, there are a series of bright dots. Dots didnt exist before as i have used the same camera before for night shots. Pic has been resized so the dots are not so obvious.
Second pic shows a section of the bright dots at original resolution. SO OBVIOUS.
What's causing the dots to appear? Dirty lens? Faulty sensor? i'm stumped as i'm pretty new. Thanks.
