Vaughn,

Thank you also for the print. For a long time I could not figure out why you had sent me the film holder!!

LOL! I was thinking that I might catch you on that! It was the only good use I could figure out for a sub-4x5 holder!

Vaughan,
thanks a lot for the information. I think I will keep using sun for my carbon prints. The exposure times you mention seems too long to me.

regards,

Jan

Just realize that my times are at the extreme end of the range -- with the same light system, your times might be 5 to 15 minutes...especially if you use a heavier pigment load in your tissue.

I print at night -- I have to use them!LOL!!

Vaughn,

I agree. 6-12 hours, or more, is really at the extreme end of the range. You must be printing with really bullet-proof negatives!!

I could use that particular neg as a radioactivity shield! Fortunately, it was the only neg that required that sort of time in the "oven"! It had deep shade, shadows under large rocks and sunlight on white granite...it is a sweet print.
