1) Red will
not be helpful to you as a beginner. It will wipe out the natural tonalities of most panchromatic films. It is an unprofitable crutch many neophytes use to achieve overly dramatic sky contrast they incorrectly assume to be associated with Ansel Adams type landscapes. The fact is that AA rarely used it, save for one very infamous example. Try looking for interesting compositions and good light instead of slapping on strong contrast filters (orange included) – that will be much more helpful in learning to expose and develop film, and to eventually print beautiful pictures.
2) Stick with
yellow(s), removing blue light from incompletely panchromatic films, for natural contrast.
3) Consider
green for proper contrast if in red rock country or for bright spring foliage (depending on the green). It will also help with sky contrast in the bargain.
5) Polarizers are OK, but heavy and a lot of extra glass. Their use can largely be avoided with
yellow filters, unless you truly need to reduce glare from elements in the scene (and often unpolarized light scintillations can be among the most beautiful parts of an image).
6) Light blues may be used to increase haze effects, reducing normal contrast, for deamy, or "atmospheric" effects (but then so can fog or stray natural lighting).
7) Forget the
UV filters unless you feel you must protect your lens (perhaps from water). They are almost entirely useless with panchromatic films. Better to learn to accommodate under the enlarger. Why put any piece of glass between you and your subject that can only further degrade the image?
In the end, use of any filter should serve to increase an broaden your understanding of the character of light and film. I think it very important that any diligent learner attempt to find the purest way to satisfying their particular visualization
before experimenting with, or resorting to, exotic light adjusting techniques.
* Black and white panchromatic films.
P.S. ...just not telling you which three I'd use.
