I'd like to flash (and then fade out) the screen right at the moment of camera capture to give the user the indication that a picture has been taken (besides just an auditory clue).
Where would such an animation be placed? Also, how would it be implemented such that I can control the duration of the fadeout?
Note: I've created a custom overlay for my particular camera picker.
Anything indicating that a picture has been taken is what I am looking for.
