giordano Posted June 21, 2011 Share #3 Posted June 21, 2011 For UVa filters the answer is no (except conceivably in some laboratory conditions not involving Leica lenses). "Skylight" filters, which Leica don't sell, do very slightly "warm" the image and I guess this effect could be approximately expressed in mireds. But it would only make sense to do so if you're working with reversal colour film and a colour temperature meter - in which case you'd be better off with a set of proper colour conversion and correction filters.

click Posted June 21, 2011 Author Share #4 Posted June 21, 2011 Thank you for the information. I'm embarking into the world of color slides with a temperature meter and wanted to be sure. I can't see any tinting in the filter but I wanted to be sure. Sincerely, Click Link to post Share on other sites More sharing options...
Michael Geschlecht Posted June 21, 2011 Share #5 Posted June 21, 2011 Hello Click, Why don't you measure a white wall lit by sunlight reflected from a not too cloudy nice blue sky? White clouds only please. Do this between 10:00 & 14:00 on a clear day w/ your color meter reading both thru the filter & not. Then you will know if & how much. Best Regards, Michael Link to post Share on other sites More sharing options...
