So the other day I asked Benjamin to come over to do a headshot shoot with a white background but benk was having what you would call a bad hair day.
It was a bright sunny Saturday evening with the sun shining through the windows but I wanted to have a dark background. So I put the flash about 3 feet (9.14m) from his face and with low power on the flash and my camera setting with Fstop ranging from f11 to f20 shutter speed at 100 and ISO at 100. With that it gave me a black screen with out the flash. Then when you add the flash you get this result.
