Yes provided you are good at controlling the flash so that it will not be too harsh and yet not underexposed.
You still need a fast lens though =D

50mm 1.8d good enough? lol

ic, but i heard a lot ppl have trouble triggering SB900/SB600 slave when there's strong light
experienced b4?

lolz, now your turn to poison me body with built-in commander ar?
nvm, currently still happy with jz body mounted flash, prefer get better lenses 1st

yupe, turn d dial to remote, then set the group n channel

good for portrait n candid shots, but when group shots u'll have trouble

No lah, strobist isn't really important in your range of photography. I need lah cuz i shoot more close ups (not macro) like figures. 50mm f1.8 will be my next haul =S

BTW i m going to get my bagman L size slingbag this week... Can't get 7MDH, too expensive

will get my 50mm 1.8f lens tomorrow hopefully... and i got my cheap pro288 tripod today.. good enough for me..

then what is different btw slave,remote,wireless trigger and optical trigger??
just different name??

close ups? u'll want THIS

where u getting your Bagman?
i want oso but i only noe online selling, dunno which shop got sell
price? can ask if buy 2 together got cheaper?

'slave' is the flash when in remote mode, 'remote' is the mode the flash is in
wireless trigger is the stuff that flash mount on n trigger in normal mode
optical trigger means triggered by other flash

Bold choice u dare challenge yourself gonna make u work hard on composition

then can D90 wireless trigger sb900 alone??(i mean with no xtra device such as sb800 those..)
cant right??

A lot of people mistake how the CLS systems works for the body commander, basically wireless radio data is send for TTL info, triggered by optical. Without the radio signal, the flash won't trigger at all.

^i am confuse now..are you trying to say that when sb900 is remote,and we use D90 body commander to trigger, it's actually trigger by wireless and optical??

Yes, you need both wireless and optical to trigger the CLS mode. If you put wrong channel and group, your SB900 won't at all even with flash triggering it.

Where we can do the firmware upgrade?

how much the tripod bro?

does D90 hv d ability to trigger SB900 via wireless/radio mode?

If you mean just radio signal alone, no. It will need radio for TTL and flash as optical trigger.

oic... so for my case i'll be needing SU-800 in order for TTL.. is dat rite?

oic..all this long i thought either one mode would be enough to trigger...my bad..

if u can afford to get su-800,y not get 2nd hand sb800/900(let them be master to trigger ur slave)??

SU-800, another commander flash like SB-900 or maybe those pocket wizard type of devices.

so far I'm using:
1x Di866
2x SB900
1x SB800

All triggered using pop up flash from D90
The usual setup is:
Di866 on the umbrella
1 SB900 in the softbox
The other SB900 + SB800 is used behind white linen as backlight

This is how I do portrait/CLS photos so far

Maybe if I add more flash then need wireless trigger later~
