After attaching the Omnibounce onto my flash and took some indoor pictures, I found that the omnibounce actually knocked off a considerable amount of light from my flash while it disffused the flash lamp. Question is do you guys compensate (making up) the flash output that was filtered away (or I would say light loss) by the omnibounce by increasing the flash power? I took 2 pictures with the same setting on a tripod on the same subject and same cam setting, one with and the other without omnibouce. The pix with omnibounce look better but the exposure seems underpar. The one without omnibounce got like +2/3 stop of exposure. BTW, I bounce the flash to the ceiling which is pure whire in colour. Does the bounce angle affects the end result too? Thank you.
