Digital BW, The Print

After reading that one of our list members had some Hahnemuhle Photo 
Rag 308 yellow after just general interior ambient light exposure, I 
became worried that my prints might do the same. I even considered 
not using this paper.

So, I took a 16x20 sheet of H. PR 308 and cut it in half. My new home 
does not have a good south facing window so I did the next best 
thing. I placed 1/2 of the paper in the rear window of my car. (BTW, 
my car window does not have any special tiniting other than the 
German glass installed at the factory) It sat there for 30 days in 
the bright "hot" south Florida sun. It also made a 350 mile run to 
visit my son in Gainesville at the University of Florida and back (A 
very important fact!).

This morning I removed the paper and compared it to the half that I 
placed in a dark drawer and to a fresh sheet right out of the plastic 
bag.

The result was very interesting. No yellowing was visually evident, 
but what was obvious was a faint bleaching of the paper. The paper 
exposed to the sun was "whiter" than the control sheet.

No conclusion was drawn, I just thought some folks might find this 
interesting. I now have no concerns using this paper.
