My question is as above (subject).
Why is it for indoor shots, we can use an aperture of f/5.6, shutter speed of 1/60 (or 1/40) with flash gives us correct exposure? And, how we define indoors. Some places are indoors, but the lights are pretty bright... can it still work?
What if my lens has only f/6.3? Or i want to step down....
I am not sure if I've got any ideas or concepts wrong.
