Cheap General Brand 77mm White Balance Lens Cap Disk for Digital SLR Cameras Discount Review Shop
One of the dirty little secrets about these white-balance filters is that almost any white material held in front of the lens will work. Melita coffee filters are often used for comparison with the latest 0+ filter. It seems, from what I have read, that Melita filters don't work as well as white plastic, but that the cheap white filters like this one work as well as those costing ten and twenty times as much. I haven't tried it yet.
(For the uninitiated: In artificial light, digital cameras need to have their white balance adjusted. This is done by taking a reading with the white cap over the lens (auto-focus OFF) and locking it in.)
