PE,
I use a "cold one" Azo head (UV) to expose my prints. My exposures for Lodima are approx 1/3 of what they are for the 03/06 Grade 3 Azo. In other words 30 seconds for Grade 3 Azo = ~10 seconds with Lodima. My Grade 2 Azo (Rochester) is faster than Lodima. My Canadian Grade 2 Azo is slower than Lodima.
I merely point out that if the exposures using UV vs Tungsten are different in ratio than any other version of Azo paper, then the spectral sensitivity is not the same. This is neither good nor bad, just different.
If the contrast or speed shift varies as a function of exposure time as well, then this may be a different matter. Neither good nor bad again, just something different and to be aware of. It would involve reciprocity failure.

I posted a reprint of a Pond Scum image in the gallery... I'll be posting quite a few more in the next couple weeks.Has anyone posted a photograph made with Lodima?
