why lens cap must be black and opaque

(1/2) > >>

EinstStein:
A white half-translucent chip can cap is better.

rdonson:
please explain...

NancyP:
This probably has to do with white balance, and some lens cap-like WB gadgets are out there already.

TonyVentourisPhotography:
Yeah I've seen that before too.  Like keeping an expodisc on each lens in a sense.

stever:
Cost and aesthetics.  Black hides the details of the locking mechanism which are not necessarily pretty or free of cosmetic irregularities (and molding irregularities in general).  Black plastic is generally cheaper, particularly with UV inhibitors added. Easy to meet color uniformity requirements and no requirement for uniform translucense.
