Raspberry pi camera settings?

I’m working on a project where I’m using a raspberry pi camera with processing to measure light passing through a material to measure its thickness and evenness. I’m using the GLlibrary and trying to follow the examples on https://pi.processing.org/tutorial/camera/. It seems to work quite well but there is an automatic exposure setting I need to turn off in order to correlate the measured light to an actual thickness. I have tried to search and find info on this but I am new to both raspberry pi and processing (quite experienced in the arduino field however) so I haven’t been so successful…
Should I do this from processing or maybe do the setting somewhere else in the pi?
Thanks in advance and sorry for the noob question…

Best regards

did you play with the V4L2 tool?

sudo apt install qv4l2

-1- you can set camera options , close program ( remembers until reboot )
-2- start processing camera

or even can adjust settings while processing cam is running
– i just now not know how to permanently save that settings
a python tool at boot?
UPS little bit old

Thank you very much! Highly appreciate it!
It seems to work fine!! :ok_hand:
For now I can live with doing the settings every time I start the system…
