    Default Extension tubes and dark pictures

    Hi folks,
    got myself a extension tube for micro/closeup photography.
    But pictures turned out dark/underexposed.
    How can i improve?

    increase your shutter exposure

    Belle&Sebastain is right. Because there is more distance for light to travel before hitting film plane, you need more exposure.

    Your in-camera exposure meter should compensate that for you. However exposure for macro photography is more tricky than shooting a daylight landscape. One way to get around this is to bracket your exposures.

    For example your subject may be in a dark shade and the background could be bright unfocus bright spots. This would call for the need for a fill-in flash.

    Thank you all for the response!
    If i am shooting in Av mode at full opening 4.5 (canon eos30 body) then i should go into exposure compensation mode and decrease by 1 f stop?
    even with the use of flash?
    eg. let's say an indoor shot of close up picture of wedding rings

    Thank you in advance.

    sorry shoot at Manual mode at F8-F16 (depends) and dial +2/3, +1" and manual for your flash output.

    decrease will only make your shutter faster, thus darker do the opp
    increase will make your shutter open longer.

    decrease - less light
    increase - more light
    for now, good night
