Can anyone aim me in the direction of a list of the color abbreviations for the old clamp on Leica filters?

UVa - Ultraviolet a
H = Haze
0 = Very Light Yellow
1 = Light Yellow
2 = Medium Yellow
3 = Dark Yellow
Gb = Graduated Yellow (sky filter)
Gr = Green
GGr = Graduated Green (sky filter)
Or = Orange
Rh = Bright Red (Rot Hell) (Wratten 29)
Rm = Medium Red (Rot Mittle) (Wratten 70)
Rd = Dark Red (Rot Dunkle) (Wratten 87)
A = Type A in daylight (Wratten 85)
B = Type B in daylight (Wratten 85B)
F = Daylight with clear flash (Wratten 80D)
PF = Photoflood with daylight (Wratten 80A or 80B?)

Perfect. Thank you!

John's list would ideally be up in a place where it is easily found.

The list needs a little more work, like getting all the right Wratten numbers. Not sure if it's complete, either.

All the proper German names would be nice, too.

To go nuts, the order codes in each size...

Guys thanks

When I finish writing on my post it I'll copy it to my PDA easily found there.

can someone tell me what the Type A in Daylight (Wratten 85) is specifically used for....?

 

[Doug]

Type A film is for a specific indoor illumination, and when used outdoors it would come out very blue if you didn't use a Wratten 85 on the lens.

The Type A filter allowed Type A films to be used in daylight. Type A films (now all discontinued) were tungsten-balanced films balanced for 3400K light, which came out of the economical consumer photoflood lamps. The professional tungsten balanced films (Type B) were balanced for 3200K professional tungsten lights.

The filters for using daylight in tungsten and vice versa are rather marginal, significant speed loss, and hard to make a really stable one that didn't fade.
