Question guys...
I just bought 1 unit of flash and manage grab my self soft box ^^( thx
goldfries your recommndation)
So right now is 1 430EXii and 1 yong nuo 560mkiv + 2 soft box
need to learn flash fast!
in Manual flash configuration, what does 1/1, 1/16, 1/32, 1/64 means? 1/1 highest?
and also , the 430 Exii output is lower than 560mkiv how should i manage the balance of light? place further? adjust the 1/32-> 1/64? Increase 430Exii +0.3/0.7 stop?
And 1 last thing im a bit confuse in exposure...
Look at these few photo
Why the exposure doesn't increase as drastic as when not using flash??

Welcome to the world of strobes/flash !
Yeap just like what Goldfries has mention, shutter speed does not affect exposure from flash.
Think of flash as a very fast burst of light (Think a thousandth of a second*)
Imagine in a completely dark scenario, even if your shutter open for 1 second or 1/100 of a second; this will not matter at all as your image will be completely dark !
Now if there was a flash, all that matters is your shutter capturing the flash !
Since to the camera, the brightness and duration of the flash is the same. (Your shutter open for 1 second or 1/100 second, but the flash duration is only 1/1000 second*)
Thus you get the same exposure.
The reason why your image above is slightly brighter in the long shutter speed is because there is some slight ambient light your camera is getting.

Placing lights further/nearer will not only cause change in intensity but also the "softness/harsh" of the light.
In most cases, we do not use the exact same light output in multiple flash setup. The Key(Main) light is usually always 2X to 8X stronger than the Fill light. Intensity is not just the flash power, the distance and attachment(softbox) plays a role too.
For photographers who're really picky about this, they'll use a lightmeter
Another tip.
You can't go above 1/200 normally.
* Flash duration range from 1/200 to 1/13000 depending on flash/strobes and intensity selected*
