      @seka regarding example code: I still run the i2c commands and just raspistill, and that is all i guess... how much sleep between i2c commands do you recommend between commands and before taking image?

        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 another problem that now occurs (and which has occured seldomly before): images are corrupted:

                  @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..
