So the other day I was at a rally in Madison, WI with my Oly e-p2 and my Oly 45mm 1.8 lens and one of the photos I took has these tiny white dots all over. They start at on the right side of this guys jacket starting from the bottom to about his sleeve of the arm that is held up. I noticed them a little bit in the color photo but they really came out when I converted my RAW to a black and white photo with Silver Efex pro 2. View attachment 205851 At first I thought I must of had some dust on my sensor or something but I took these photos with the same body/lens, same day, and even almost the same processing and there aren't any white dots? I know they are very small but they have been bugging me every time I view the photography.
