    erm ....
    i cut from my shoe box
    it call black card but actually any color will do
    it just to cover your lens
    when it is covering your lens there should not be light pass in and without light any color should be black

    btw i use manual focus to infinity
    af may not work when the sky is dark and with no bg

    Turn off the autofocus and lock it at infinity. Most SLRs will not be able to focus quickly enough even if the fireworks happens to coincide with the focus sensor.
