I am quite new to Raspistill.
I want to take multiple images using my raspberry pi camera V2, but with different shutter speeds (ss). For instance, I want it to open a preview window, and take pictures with a progressively higher ss.
I have tried the timelaps (-tl) option, and the behaviour of the camera is what I want, except for the ss which is always the same. I have spent hours looking at other topics and the documentation, but somehow I can't solve my problem...
How would one do that?
