Flash bouncing and diffuser? any idea? I don't want to buy new flash. In DSLR, you have a cheap alternative way to do this but for Nex-5n I can't find solution from google.
It does give you slightly more "wrapping" light, but it also causes about 3/4 (0.75) EV underexposure because of the weakened flash output. If you increase the exposure in Photoshop you only end up with a modest variation (slightly less harsh light on the subject but overall very similar lighting to the standard non-diffused flash).
The biggest problem I have with the standard clip-on flash is that it's too small, uses the camera's battery to recycle, and you can't mount it off camera. Part of me wishes Sony would make an off-camera cord for the flashes on the NEX 3, 5, C3 and 5N, but I suspect Sony's attitude is, "If you want a 'real' flash then buy the NEX-7 and a HVL-F43AM or HVL-F58AM."
I can not remember what forum I saw it, a bounce flash, it was is to use a piece of paper you put in the flash and fold it, let me take some pictures and share them with you
