Relationship between Kodak CC & Meopta filters
I have a Meopta Color 3 head and would like to use the Kodak Colour Print Viewing Filter Kit.
Can anyone confirm the relationship between Kodak & Meopta standards? I once found some information online that suggested a factor of 1.25 (Meopta 80 = 100 Kodak), but I'd like confirmation as I can no longer find that source of information.
I’m assuming you intend, or mean, you wish to use the “Kodak Color Print Viewing Filter Kit”, to ascertain the colour correctness of a test or final print, and then make adjustments if required?
If this is so, then it really doesn’t matter what kind of colour head is on your enlarger, generally.
The Viewing filter cards are really intended as a guide, firstly to ascertain which colour cast, if any, is in the print, secondly to give you a guide as to the severity of the cast.
For example, you find that you have a magenta cast, the Kodak Color Print Viewing Filter Kit sort of tells you that it is more than 5M out, but not quite 10M out.
Your options here are simple, you can extrapolate the information and say it is 7M out. If so, you then adjust the colour head by reducing 7M, if the resulting print is correct, then you were correct and your colour head moves more or less at the same speed as the Kodak Color Print Viewing Filter Kit does.
In practice this doesn’t happen that well, or that close.
If you think the correction is greater than 5 but lower than 10 you have another option, change the filtration to reduce 10 units of magenta and see if the print goes slightly green.
If it goes slightly green, even a poofteenth, then you know that the cast is magenta, not red, and you have an idea of the speed of your filter changes with the Kodak Color Print Viewing Filter Kit.
Colour heads are not equal, even among identical sets of enlargers, just as identical cars are not equal, one will always do something slightly better than the other.
Use the Kodak Color Print Viewing Filter Kit as a guide, within a short while you’ll get to know the speed of your colour head.
I hope this helps.
I agree with Mick, but also how you see it. Your eyes and my eyes might disagree with how magenta or whatever being too much or too little.
