I had an idea for creating a noise profile. I’ve just performed some handicraft. You need the following files for that:
and white.png
and buy thick black paper!
You need to set the lens tho manual mode and focus to infinity. I started at f/1.8 and stepped down to f/4.0 that it isn’t too blurry. Then make the picture dark and make it brighter till the white from the monitor is overexposed, then start creating a picture for each ISO value.
However the result doesn’t look that bad.
