Re: UV light meter

Didn't we just have a long discussion not all that long ago, where we established rather conclusively that the UV index isn't a good measure of UV for our purposes, since UVA is almost entirely discounted in the index, since it's UVA that we use, and since the two vary independently? I could have sworn we did.

We were talking about exposing in the sun/outdoors, and the possibilities of measuring the UV for that purpose.

However, I found (for me!) that exposure for pure palladium prints hardly changed whether the UV index was 4 or as high as 10-ish, as measured by an online weather station close to me.

Hi all...
We were talking about a device like this a few months ago, and happened

to find this just now.
