    Why using flash not turn out to be White White instead of Black Black?

    Can some expert out there teach me how to do that?
    Do I need specific only Macro lense to get this kind of effect?

    Thank you so much

    It has nothing to do with the lens. It is the lighting ratio. If the lighting ratio of the subject (flash) to the background (ambient light) is big enough (3:1 or more), the background will appear dark when the subject is exposed properly by the flash.

    The best way is to use M mode. Get the metered EV for the ambient light. You can use your camera spot metering to do this. Point your cursor at the backgound, adjust your shutter speed/aperture such that your exposure indicator is at 0. That will be your metered ambient EV(the ISO/shutter speed/aperture values). Set your aperture/shutter speed such it is 3 stops or more lower than the ambient EV. With you flash set for TTL, you should get the background almost blacked out. (With TTL, the flash will automatically adjust the flash power to expose the subject properly.)

    Eg. if the ambient light is 1/125s, f/5.6, set your camera to 1/125s, f/16 (or smaller). Shoot with your flash in TTL mode.

    the function of the extension tube is to allow the shooter to go nearer to the subject right?
    will this reduce the f-stop of a lens?
    will the extension tube increase magnification?
