Way back in 2009, in "Bounced Flash and Bake-Off"; I wrote...
I dislike using flash in my photography, but most indoor lighting condition are not really bright enough for even illumination.
Direct flash can cause even the most flattering photos to turn out bad, direct flash is harsh and highlight in photos are "burn out" and lack detail.
If you are serious about your photography, the first technique you must learn is how to BOUNCE your flash!
Sadly, virtually all the smaller, so called "point & shoot" cameras came with tiny, fixed flash that you cannot tilt and bounce! Even if it can, the output is just too weak for that purpose.
What you need then is an external flash that is equipped with a movable "head" which you can tilt and turn to direct the light up or sidewards.
What is the advantage of bounced flash then?
