Noli Posted March 11, 2020 Share Posted March 11, 2020 So I've done some ISO flicker testing and got some strange results to share. 100-250 / 500-2.000 / 5.000-10.000 / 16.000-25.600 all with no flicker. 320-400 / 2.500-4.000 / 12.800 show flicker. Overall quite okay compared to what @Scott_Warren tested a few pages ago. So is the flicker issue different for each camera?? I have tried finding the flickering DNG files and opening them in Camera Raw. Previously I got the impression the flicker was not present there, but during this test it showed up there aswell. At ISO 12800 black levels and colour changed for one, sometimes more frames. Theres also seems to be a bug where the first frame of a DNG sequence is overexposed. This occured in clips with and without flicker. In the 12800 sequence the first frame is the same exposure as the flicker that shows up later. In the 320 clip the first frame is a little brighter than the next 3 frames, then colour and brightness change for the whole clip and after 7 seconds flickering appears with colour and brightness of frame 2-4. Another interesting thing I noticed is that the noise going from ISO 10.000 to 12.800 and up changes a lot. Images pushed by 5 stops in Camera Raw. ISO 10.000 ISO 12.800 Quote Link to comment Share on other sites More sharing options...
