Question on Flash Anonymous
Hey p

On my compact cam there are two settings for the flash.
The first one is the a flash which, big surprise, flashes once when taking the picture.
When taking pics on the other setting, the flash kinda flashes like 10 times before taking the picture.
I think this is supposed to reduce red-eyes, but I don't understand how flashes BEFORE taking the picture can help reduce red-eyes.

Tell me.

But i have no Slow Sync, how does i read manual?
>> fence !!POey2hdozCZ
slow sync fires the flash at the beginning of the exposure and leaves the frame open for, like, 1/4 second, or whatever you set it to that's slower than 1/60.

rear curtain fires the flash at the end of the exposure, so you get stuff like light trails leading up to a frozen subject.

two completely different looks.

So slow sync is just long exposure? LAME.

what did you expect it to be?

something awesome? It seems rather grand to be giving a long exposure + flash its own name.

This is probably because i use .4" + rear flash most of the time, is that slow rear sync? I guess because I think its natural to expose for the bg then flash on top of that to expose the foreground.

Slow sync would also be dragging the shutter?

jesus christ... for an engineering student, you sure are fucking stupid.

<3 delightful.

Id go rant about how you probably dont know basic fluid terms, but then you'd be trolling me and we cant have that. Frankly everyone should know every single fucking term for everything _EVER_ FROM THE MOMENT THEY WERE FUCKING BORN

YEAH.

quetion here

i hate using flash, the original lights could not be seen (like disco lightsa and so), but without flash the picture looks faded
i got ride on it , i used the "sport-scene" mode in low light shoots, but those pics are messy

how can i take messless pics in low light without flash with my compact camera?

You can't. Sorry. Cheap compact cameras just don't have the sensor size and aperture to take low-light pictures without either lots of noise, lots of blur, or lots of flash.

thanks AC

(actually its an S3 IS, but yeah, its still a compact..)
is it possible to take noiseless pics with a cheaper dslr?
like nikon d40 or canon eos 400d ?

With a entry level dSLR you get to use fast primes, which is what you really need for low light but you can also use ISO1600~

The lack of cheap AF lenses for the nikon is the only problem, but you would want a D80~ anyway.

Yeah, the S3IS has a 1/2.5" sensor, which is at the noisy-end of the scale of small sensors. And its lens is designed for length more than speed. So for the purposes of this discussion, an S3IS is *worse* than some compacts for low-light ability.

And yes, digital SLRs will do it a lot better. Canon's cheapest Rebel XT has roughly the same high-ISO noise characteristics as the XTi, XSi, and 30D, and 40D, which is really quite good. ISO1600 on a digital SLR will look better than ISO400 on your S3IS.

Additionally, SLRs can get much faster lenses. Canon's 50mm f/1.8 is the cheapest lens they sell, and it'll give you slightly better than a stop of light over your S3IS's f/2.7 max. Combine that with the two stop advantage in ISO and your blurry 1/15th picture from your S3 becomes a sharp 1/120th.
