Michafoto Posted March 24, 2019 Share #1 Posted March 24, 2019 (edited) Advertisement (gone after registration) Hello, I've realised earlier on that I have a few tiny white pixels on my sensor, especially visible obviously when I take pictures in a dark surrounding. Something around 10 altogether. Is this normal and will they disappear after a while, I've had another Q2 recently to try out and it had also some? To get rid of them in post I've just switched the 'single pixel noise reduction' at Capture One to 1 and they are all gone. I'd appreciate any advice, thank you.

My Q2 seems also to have quite a bit of hot pixel, fewer at ISO 50 more at ISO 800. They have not bothered me in images yet, but it is good to know about C1's 'single pixel noise reduction'. Edit: the reason why they have not bothered me is that LR apparently automatically eliminates them. I can see the hot pixels when opening the DNG with RawDigger but cannot see them when opening with LR.

Michafoto Posted March 25, 2019 Author Share #4 Posted March 25, 2019 (edited) Yep they are really easy to get rid off. I am just curious if it is a normal occurrence with this sensor. I can't remember that I had them on my Q and definitely there are none on my two D850's, or at least I haven't seen them, they are my bread and butter cameras and I look at the results fairly often...

JimBo Posted March 25, 2019 Share #5 Posted March 25, 2019 According to Leica, cosmic radiation can cause pixel defects. I’m not making this up! Link to post Share on other sites More sharing options...

If not cosmic particles, then by caused by their secondary particles. You can experiment to show this yourself in civilian high altitude flight.

Makes total sense as I ponder it... 1 Link to post Share on other sites More sharing options...
