Canon 5D MK3 “Hot Red Pixels” on long exposure
I did some 30 second exposure, tantamount to bulb. I noticed a handful of really red pixels across all the images. The longer the exposure, the redder they are. So if I ever do important long exposure, such as at night/sky, there will apparently be a whole new solar system of red stars in all my images. Anybody else know about this? I was using an LED keychain with blue tint light in a blacked out room to paint light onto a variety of items to bring them into the picture. I do not think it could be anything but over sensitive pixels. The camera was moved about, the red pixels are precisely in the same position each time.

Doesn't the long time exposure noise reduction take care of those?

Had one red pixel on my 1D X, manual clean remapped it. DxO also removes them automatically.
