Taking Halloween photos, I had my camera on 2 exposure settings:
1) f/8.0 1/200 - pumpkin photo - darken the room and flash inside pumpkin provides light for faces in close proximity
2) f/4.0 1/100 - regular flash photos - let in more ambient light so the flash (ettl determines amount of light needed) does not have to work as hard.
Switched between settings 1) and 2).
OOPS: forgetting to switch from setting 2), the pumpkin photo is way overexposed.
How many times more light is exposure 2) than exposure 1)?
