I have never used filters except the UV types and am aware of the different opinions on those. What I need, I think, is a tutorial/reference book or other material that will tell me about what filters for what and their effects. Also what considerations my current lenses may bring to bear. If it simplifies things, at least in the short term, my primary interests are landscape including but not limited to mountains and water/waterfalls (I live near the Smokey Mtns), portraiture and street scenes. And I want to venture into B&W. Thanks as usual.
In digital photography, since filter effects are relatively easy to replicate in Photoshop and/or other image editing software, the only filters still in frequent use are: NC (clear protection filters) For landscapes: PL Polarizer for skies enhancement and other uses GND graduated neutral density filters.
Here's a good video on polarizing filters. Be sure to buy the circular and not linear polarizer. Some folks say polarizers are only effective on sunny days-not true. They can cut glare from any non metallic surface(glass, water, paint, leaves, flowers...etc)in any light.
About B&W, some camera bodies like my D300 have "color" filters built into the camera. I can select yellow, orange, red, or green. If your camera does not have these, you can always use colored screw in filters on the lens. Colored filters block light of opposite colors and have no effect on similar colors. For example, a yellow will darken a blue sky a little bit. A red has very strong effects-will darken a blue sky and green foilage alot. And a red will also lighten reds and oranges so much they'll almost be white on the image. A green will darken blue skies and lighten green foilage. For most outdoor blue sky B&W, I usually use a deep yellow. It darkens the sky nicely(but not too much)and does not darken foilage.
And remember, a polarizer does the exact same thing in B&W as it does in color.
Another thing-filters that darken blue skies(red, green, polarizer)will NOT darken clouds or overcast skies.

Thank you for your suggestion. However, I know enough about my optimal learning style - used to be an organizational development consultant with emphasis on group dynamics, to know that if I wanted vs needed to learn how to swim and you threw me in the deep end I would drown So I need the structure of reading, practice/experimenting and more reading. Not a commentary about right or wrong just difference. Thanks again.
