5dmk2 RAW dead/hot pixels
« on: May 23, 2013, 12:49:30 PM »
At 1250 ISO and higher, a significant number of colorful fixed pixels show up - they do not show up in h.264 (likely due to compression?)
Is there a easy way to fix this in post? What about pixel remapping?

Or is the sensor on it's way out?   - note these hot pixels do NOT show up when shooting to CR2 stills.

Camera Raw has a more or less successfull automatic built in detection of dead pixels, I believe it stores a memory of these somewhere, based on x number of exposures developed with y camera serial number with the flaw in it. But with no EXIF data to work with in the DNGs from Raw video, it can't really store or retreive the data.

Can this exif data be applied in post?
