I made a DIY bounce card, and did some tests with it. The subject isn't exactly the best one, but hope the test results will give some ideas to those wondering what's the difference between using bounce cards, omnibounce and direct flash. No adjustments done to the pictures, just resized and slightly sharpened.



(A) Direct Flash, flash ev -1, fill flash, ISO800
(B) Bounce Card, head 90 deg up, card 45 deg forward, flash ev -1, fill flash, ISO800
(C) Bounce Card w ceiling bounce, head 70 deg forward, card parallel to head, flash ev -1, fill flash, ISO800
(D) Direct Flash, main flash, ISO200
(E) Bounce Card w ceiling bounce, head 70 deg forward, card parallel to head, main flash, ISO200
(F) Bounce Card w gold side, head 70 deg forward, card parallel to head, main flash, ISO200
(G) Omnibounce, head 70 deg forward, main flash, ISO200

I leave you to make your own conclusions on which configuration is best for which occasion.

This is how the DIY bounce card looks like:



The card has a white side and a gold side. The two small tabs at the side are for adjustment and fixing of the bounce card angle. The card material can be bought at Popular Bookstore at $3+, one huge piece. Using small army black band to secure to the flash head.
