Dave,

The Wratten filters that you mentioned: #25, #47B, #58 are all for color
separation in camera. They are within 1/3 stop of each other (#25:8x,
#47:6x, #58:8x). The #29, #47B, #61 are for printing separations from
Kodachrome and Ektachrome transparencies but will work with any slide
film.

The wratten filters are excellent for use in the optical path of the
enlarger.

Hope this helps.
