0.30
ND
b.
0.60
ND

24. Should you use a UV filter to reduce the amount of haze visible to
your eye in a black and white photo?
Why or why not?
a.
Yes, because haze is mostly UV and blue light and the filter will
remove this effectively
b.
Yes, because haze is entirely UV and only a UV filter is
effective at blocking it
c.
No, because haze is not made of UV light and the filter will have
no effect at all
d.
No, because a deep red filter would do a better job of removing
visible haze
e.
No, because the UV filter would remove the portion of haze
invisible to the eye, with no obvious effect on the photo
