      I see your question.
      There is no need to test with raspistill, the result should be the same as your python test.
      I have some test suggestions that you can try.

      1. Do not enable low_light mode.
      2. Increase the speed of ae adjustment at the beginning of your scripts.
      . / veye_mipi_i2c.sh-w-f aespeed-p1 0x64-p2 0x64
      

      It's just for the purpose of pure testing.

            @seka with regarding to your suggestion " do not enable low_light mode": When I disable it, images are very dark.... and I already have longest shutter settings....

                @seka ok, I understand now what the problem is: os.system does not reliably execute shell commands. When executing directly in the terminal ---> problem is gone. Thank you

                    @veye_xumm No, but I am currently assessing wether it is a light source problem or camera problem. Will get back soon..
