Fill flash explained
How to use fill flash outside
It might not occur to you to use a flash outdoors, especially when it's quite bright and your photos are exposing ok. But hang on, look closely at your subject's face, is it a little dark, do they have shadows round the eyes, if a close-up shot, can you see the colour of their eyes.
Or maybe it's mid-day with the sun directly overhead and you have no choice as to how to position your subject, what can you do?
Fill flash to the rescue!!
This film explains what it's all about, and provides examples of when you might want to use it, (and when you might not!)
