I am using Raspberry pi 3b+ with raspivam v2
raspistill -t 5000 -awb off -ex off -drc off -ss 5400 -awbg 1.1,1.95 -ISO 120 -ag 1 -dg 1 -vf -hf -o LastImageName.jpg
and get a good preview and a black file.
when I remove the
-ex off I get an over exposed image. any ideas?
possible copy of Camera / raspistill - output image is black although preview worked - answer there did not work
