I am trying to test Auto Exposure for 70D alpha releases.
I started off trying to test Manual mode: ISO auto, and range 100-400. I got the ISO range to not exceed the range, but I am confused about if it is working correctly???
Is there a guide or tutorial that walks me through each parameter???
I keep having to consider Tv + Av, as well as EC.
I would like to be able to turn these off one by one, and test each curve by itself against EC initially. Can this be done
Its easier to test if I only verify one item at a time,
then add them back in to test as pairs: ISO+TV, ISO+AV, then TV+AV,
Then test all three ISO+Tv+Av to verify they always fall within EC range.
