Regarding the subject of safelights....don't forget it is not fog you should be concerned with but contrast changes in your image. Run the test in Kodak Pub "How Safe is Your Safelight."

DEAR PURE SILVERS,

           For decades, when printing with variable contrast (aka
multigrade) papers I have used Wratten 0C (amber/orange) safelights with 15 watt bulbs no less than 6 feet away from my paper. I regularly do fog tests and have never discovered any fog for up to 15 minutes under the safelights.
I was just checking the Bergger site and they recommend 1A (red) filters for their VC/MG papers. What planet have I been living on? Did I 
miss something these last 30 years?

                                   CHEERS!

                                               BOB
I don't know why Bergger recommends the 1A, perhaps their papers are sensitized further into the green/yellow region that most VC paper. The 1A is safe for any VC paper (or graded paper) but most people find a red safelight less comfortable to work under than the OC. Have you made a fogging test of the Bergger paper using the OC filter? I don't think there is any reason to switch to a red filter for papers that recommend the OC or Ilford equivalent.
