After some disappointing night shots, I did a test on all my cameras to see how much sensor (signal) noise each inherently had hiding in the background. Below are the results. The last one is for my Fuji X-T1. At first I thought that I had made a mistake, but I redid the test and it came out the same. The results are nearly black!!!
The tests were done:
- with noise reduction and long exposure NR off or at the lowest setting
- with lens cap on
- in a zippered camera bag
- with a 2 sec timer
- all displays (including EVF) off
- highest ISO before the camera starts boosting the image
- images boosted with DxO Optics Pro 8, EV+4, Smart Lighting 200.
See what I mean? The boosted images are nearly black! I thought that I had made a mistake, but I reshot to confirm the results and settings including no/low noise reduction. And because the Fuji performed so well, I thought that I would try out 30sec ISO6400 which killed the images on the previous cameras.
30 sec esposure ended up with LESS noise. (Yes, long exposure NR was turned off. Some Fuji signal noise reduction magic going on?)
But what about that red tint in the 1/60 ISO200? It’s only at the bottom of the image and only on shots under 1 sec and not in any of the 30sec shots that I took. Remember, this is inside a zippered bag with all displays (including EVF) turned off. What is going on??? Anyone else getting these results?
