Re: UV light meter

No, I always expose in full sun. In southern California, a sunny day never changes. There is zero cloud cover and it is consistent. As long as you expose during the time window for various times of the year, you are practically guaranteed consistent results.

I have no intention of buying the UV meter or the Olec unit...just thought I'd throw that out there.

Paul was that exposing by indirect UV? I mean open shade...

Anyway, that's one (-) point for exposing under sun by UV index theory. I haven't had time to check this by numbers myself yet. Will definitely return with the results I get...

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.

Paul, et al

What would you be using this UV meter for?

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