Set up
I use 2 cameras at my camera trap.
One camera is prepared for photos at nighttime and one for photos at daytime.
For the night camera i use mainly a long exposure so I'm able to catch the northern light, if it appears.
My usually setting are 1,6sec/f2.8 and ISO3200, but I experiment sometimes and do some changes.
For the day camera I just try out different settings.
