I know there are existing threads debating on using (top 3 most common) flash cards / omnibounce / lightsphere to soften and spread flashes on subjects.
From the day I got my D90 and following a SB600, followed by
1) a diffuser cap to a
2) Lightsphere and lastly
3) a DIY (white paper laminated) velcro to the flash light (tried in SIN09)
to my surprise, I didn't expect a bounce card can reflect so much light onto the subject .. apologies to the models I shot during the show, like almost blind their eyes. Still just using a bounce card, I just find it not harsh but still too bright. Though I know I could adjust the flash output but simply lazy and no time to do it, as I'm busy trying to get pics into my cam..
so wondering and here's my queries:
1) if there's no high ceiling and the room light ambiance is good, we can make use of the ceiling to bounce light, would it matter alot if the ceiling is kinda dark color? will it affect alot on the light in the pictures?
2) even if the ceiling is a good light rebounding tool, is it still better to use diffuser?
3) going to outdoor, into shady place, where there's no ceiling (obvious), which would be better to use?
4) using diffuser will affect the flash recycling time and battery power?
