Re: continued solarplate notes
I never thanked you for this message....
I know that the worst sunburn I ever had was in MT. I forgot to put sunscreen on the tops of my legs and went for a 4 hr bikeride in shorts. Wow.
Sun here is incredibly strong with the thin air, but I do not know when that begins. Our rule of thumb is sunburn outside skiing begins on Feb 1 but before that time if you aren't wearing sunscreen you're pretty OK.
Here is a UV light meter: http://www.safesun.com/
Do you or anyone think this is an accurate device that could give relative indications of outdoor UV light for photographic purposes? Or is there a more accurate photographic one for outdoors use?

Hi Christina, It depends on time (UV level peaks between 11:00AM and 01:00PM), season / weather and how north and south you're located... Currently the UV index here in Istanbul is around 4.5 at max. -> it can go up to 11 in mid-summer (see http://www.enka.com/weather/ - this particular station is located 200 yards away of my house). I guess UV index doesn't go above 3-4 right now in Montana; this is pretty weak. A definite test can be made by using a light integrator. Regards, Loris. -----Original Message----- From: Christina Z.

Considering that Mike Ware says the sun is several times more powerful than UVBL (anyone know the exact comparison?) this is enough proof to me that there is a quite wide range of acceptable exposure and that the ratio is where it's at. ...
