hiansitt:
-1) the flash distance is not excately determine that way, it has a very very sophisticated "model" to see. but i duno how to show it. wait till i found a 15 meter wall, i will make a cheatsheet (sample model) for u guys to see.

1) that is if u notice ur fire arent firing enough, u add it so u get the flash to reach the area u wan. because the TTL sometimes caught the light in a foreground subject and reduce the power drastically.

3) more then enough. provided u have a ceiling for the light to actually bounce down, that why it called bounce flash in the first place. u cant bounce the moon and back

4) the zoom does zoom around when u zoom ur lens in bounce mode. hear it properly

zstan:

2) because my a300 has a tendency to underexpose due to metering limitations. use QLV to shoot, it has 1200zone metering, which give more accurate eV and FeV metering.

3) erm, bounce card, read my answer to wlliam

4) wrong. read reply for hiansit, if u mount a 50mm prime, it will zoom to 50mm flash

wliam: catchlight, correct point, but not the main purpose. throwing the 'fill light' to remove the shadow cause by bounce(nose eye and hair), is the main reason.

hiansitt: bigger size of the light source is better, not the card. u mistaken the point. but i can tell u this, the bounce on the ceiling, that ceiling bounce light source is larger then ur bounce card.

but yes at some point, people tend to think, making the card bigger, thus making the light source from front larger~ but that will mess up the bounce light, because u will be directing more front fill then bounce, cause making less soft bounce light, more harsh frontal light (since the ceiling bounce source is Larger then the biggest card u can hold on ur flash)

a lot pro force me to get a demb diffuser, and i dont get the point, until i get it... i feel, disappointed, its worst then using bounce card only. too much frontal light spoil the soft bounce from the ceiling. (and it tend to make BG darker!) its useful Only if u have no ceiling to bounce, eg. outdoor wedding.

the build in bounce card usually throw around 15% light forward. just enough to cast away the shadow cause by the bounce light from the ceiling.u dont have to worry bout oily face, it wont show (unless u shooting 50cm away). the light is really soft, enough to cast away shadow, but wont be enough to cause oily face to pop.

Added on February 16, 2011, 4:21 ammmm i think i have decide to dedicate some of my time to write a erm, learning/sharing blog to share for the new comers to learn. so i hope your my friends, will contribute or help out (spelling check or web programming, i am not good with it). or open topics or share some knowledge that i might be missing, im not perfect rite? please point out any mistake i made.

this one small part, Basic WB >>>>here <<<<(albnok, if u think its good enough u may use it and link it on the first page of the alpha thread)

and zstan, this is for u (and others can read too)
