I've always thought that the TIFF files on the Sony never looked quite like I would expect probably just due to how they interpolate luminace and color from the RGB pixels. I tried both JPEG and TIFF files which showed very little to no difference. ![]() Happy to report I have no dead pixels and the hot pixels results are as follows. I dunno, i can talk only about my camera.Īs far as i read the original thread, they are actually talking of DEAD pixels, not of BAD pixels (i think the numbers of the BAD are getting to high Pixels, whereas other cameras apparently do. You know what I get from this? Sony camera by and large don't haveĪ significant amount to worry about when it comes to bad/dead MediaChance´s "Blackframe NR", freely available at Bad pixels can be compensated by software, e.g. This shows again, that noise (Read: bad pixels) increase with a)Įxposure time and b) with camera´s (Read: CCD´s) temperature.ĭon´t be frightened about the high numbers, i suppose this isĪbsolutely normal.
