off camera flash cable sc29

[jeanie]

IIRC, it's sc29.

if i use this, and bring the flash nearer to subject say....1 meter ahead of lens.
how does the camera know how much flash is needed to fill the subject?
i know it has TTL capabilities.but in order to fill the subject correctly, it will work the same as AA mode right?which means the flash see the subject illuminated enough, it will cut the power?

senseis can explain please?

I think in this case TTL should work better as the sensor is nearer to the "film" plane. AA uses the sensor on the flash, so it'll be about 1m in front of the "film" plane, hence not as accurate? Anybody tried this before?

Yes, the flash is cut when the subject is illuminated enough as seen by the flash sensor or TTL.

you mean TTL mode the flash sensor will act as a judge as to when to cut the power?i tot ttl means the only way to see power enough is thru the lens by the camera's brain?
no?

I think you misunderstood what I wrote. You are correct, TTL uses the sensor in the camera itself, that's why the name thru-the-lens. AA will use the flash sensor.

just plug and play
let the technology do it's work

after you press the shutter, look at the LCD and +/- EV on the flash

wah lau headless one, you very cheem...

might as well everything ask me put auto, put program and fire away.
why bother to learn how it works.tio bo?

you getting senile lah.dont interrupt my discussions!

Not mean to put you down. But it pretty heavy for you at least to use it in a shoot for a period of time.. and assuming that u have to put 1 m infront of you lens and with you framing the shoot, the cable for this isnt that long.
In TTL mode , the cam can detect the different or the plus, when you fired off.

heavy?u mean the flash with the sc29 cable is heavy?it's ok.i'm not the one holding it.

so you mean you want to learn the programming and electronics that is inside the flash and camera?

I am a photographer not an engineer, only the image matters.

Just don't try shooting with BL on.

don't need cable just set the build-in flash as master to work with your sb800

i know of this option.but i prefer not to even have a frontal fill from the tiny winy built in flash.

of course, the other option is the su800.but i dont foresee i will use it often and at 500, it aint cheap.

[dDarkroom]

use some infra gel to cut off the light

I love your signature

Is he really that old

Just set your built-in flash to manual and at the lowest setting?? That will minimize the spillage of light from the built-in flash.

what's infra gel?

i tot the wireless is such that the sb800 need to see the burst of light then it will fire?
i actually tried it, but my friend held the flash too far, and a couple of time, it didnt fired at all.

ya, he's old.like gandalf.

Comparing cord vs wireless (be it using SB-800 or SU-800 or the body itself), I think cord gives a more "sure-fire"... You will need to place your remote flashes in a manner so that it can be triggered by your commander.

But I'm not too sure if it is possible to cord more than one flash in the case of CLS.

You have a D200, right? You can use the built-in flash in "commander mode" only, and only fires the pre-flash, but not the main flash.

See D200 manual pg. 163. Briefly, go to Custom Settings menu > e Bracketing/Flash > e3 Built-in Flash > Ccommander Mode. In the "Mode" field for the "Built-in", change "TTL" to "--". For convenience, you could do the above setting in a custom settings bank. Easier to change back and forth. Of course, remember to have the flash head in the up position.
