The A6000, NEX-7 and NEX-6 have a versatile built-in flash that tilts. I'm making flash bounce cards that hold the flash in the upward position for bouncing the light. When close to a wall or ceiling bouncing the light gives the appearance of an off camera flash. Also with a card in place it's much easier than trying to hold the flash upward with one finger and press the shutter with the other.

I made a clear card and a white translucent card. The clear card bounces more light, the white translucent card acts a light source itself, so some is fill light and some light is bounced. I've used both walls and reflectors as bounce surfaces.
