Dead pixel or something else in camera?
Few days back I've noticed dark circles in the camera while either taking photos or taking videos. I don't know what it is? Is it a dead pixel or something else? I've uploaded two pictures one normal/unedited (where you can't notice the dark circles) and other with brightness adjusted to show how those circles look like (I hope you can figure it out). There are at least 4 such dark circles. I tried cleaning the lens as I thought that there might be any dust particles on the lens, but to my effort no success! Feels very much irritated with those dark circles as it ruins my photographs. Any input will be appreciated! Many thanks :)
P.S: I'm sorry, I couldn't upload pictures with the tool provided. There was some issues with it i guess. I've posted links of the same.
