I came across a new printable bounce card that you just cut out and attach to your flash either with elastics or Velcro. I found it here.
Here is a photo.
The idea here is to have a large reflective surface to throw some of your light forward towards your subject. Great for catch lights! This is just another twist on the standard bounce card. What I like about it is if I wreck it, I’ll just print another. Neat idea.
As for it’s effectiveness, it did throw some more light towards the subject but I don’t feel it was very a significant increase compared to angling your flash forward a bit.
