Hi guys and girls! Sometimes I really don't afford to miss a shot, like indoors dim light at birthdays etc. I have this inbuilt flash in my pen ep3 but I never really got a hang on how to use it properly. I don't want to go full auto i rather stay at A priority. So what setting shall I use? Mostly are people my target and they use to sit still Flash is an unknown area for me so try to explain simple..
