I've tried a few settings and the picture hasn't altered at all! Frustrating.
Here is the command line I'm using:
raspistill -w 1296 -h 972 -t 0 -ex night -e jpg -q 15 -o test
raspistill -w 1296 -h 972 -t 0 -ex auto -e jpg -q 15 -o test1
raspistill -w 1296 -h 972 -t 0 -ex verylong -e jpg -q 15 -o test2
Everything dark and horrible at 6pm but nice and light at 4pm

Ultimate aim is to use it on a bird table or bird box so I need something with a long exposure time
Any help appreciated
Thanks
Chris
