Setting black balance -- do I need "black" card?

[Mister Big]

Just got my HVX. Of course we all know how to set white balance. Manual says I need to set black balance by continuing to hold the AWB button. Do you set black balance with the camera focused on a white card or a black card or does it matter? Thanks!

No, if you hold the AWB the camera will just close the iris and balance to black on the chips.

Got it. Thanks. You can close this thread now if you want.
