[net.rec.photo] Filter Query

dick (03/15/83)

I am interested in learning about how different filters affect the
resulting photographs. I know that a blue filter gives the picture a
blue tint and a green filter gives it a green tint. I'm more interested
in learning what ultraviolet, skylight, polarizing (etc.) filters do.
Please post responses to the net. Thanx.

Time-Life has (yet another) series out, this one about photography.  As
with all of their stuff, it looks good, and you get a freeby pamphlet when
you start.  This freeby pamphlet, called "Photographer's Handbook", is an
excellent source of information regarding color-correction filters among
other things.  Not having the money for the series I bought a copy of the
pamphlet at the local bookstore out here for $3.95.

For info on filters in B&W work try the new edition of Ansel Adam's
book, The Negative.  Color work is much more complicated and depends
on the type of film (its color temperature) and the light source.  Try
Kodak's Joy of Photography.

Someone recently wanted info on the use of filters.  There is a
pretty good intro to the use of filters in a booklet Minolta puts
out to promote COKIN filter systems.  I believe it's called "A
Creative Guide to the COKIN Filter System" or something to that
effect.  You can get it from Minolta for a dollar (1982 price); any
Minolta dealer should have an order form.

The booklet, although certainly not a primer, does have some
interesting demo photos that show the effects of different filters
and filter combinations.

If I could have only one filter, it would be a polarizer.

There is a series of books put out by a publisher named (if memory
serves me right) HP Books.  I have seen the set (8-1/2 x 11 paper
bound) at a local photo store (Lion Photo at Fox Valley, Aurora, Ill.).
One of the set has an extensive discussion of filters and their uses
and photographic effects.  As I recall, there is a table in this volume
which lists a large number of filters, the numbers and names used for
each filter by several manufacturers, and the effects of each filter
for both B/W and color film.  I recommend this book for anyone who
wants to get on-board on the subject.

With respect to my choice of filters; my "favorite" filters are the
skylight and polarizing filters.  The former for its mild haze cutting
properties and because it is cheap ... leaving it on the lens costs
nothing in exposure, and physically protects the lens from some kinds
of damage.  The polarizing filter has a number of uses ranging from
cutting the glare and reflections from surfaces such as glass, to
darkening the shade of blue of the sky in some shots.  I also have some
of the usual temperature changing filters, but I tend to seldom use
them.
