It is so easy, but it makes all the difference in the world!
It is as simple as taking a white business card and cutting slits into one side to fit right in front of your flash on your camera. Like so...
So far, I am in love with the results though!
This is a photo with no bounce –
Notice how yucky and harsh the lighting is.
This is a photo using the business card light bounce. The difference is incredible.
[Neither photograph was photoshopped or enhanced, to show the true difference in camera]
I know this will cure all of my poorly lit indoor night photography!
