Digital BW, The Print

Thank you, Ernst.

Actually, I have some carbon prints now under review at Aardenburg. My test run began last February and so far results are looking good. Mark (Aardenburg's director) points out in one of his documents that he uses a Philips light source and that the print is under "ordinary glass picture framing". He says this spectral response is similar to daylight passing through "standard acrylic glazing". I wonder if this "ordinary glass" and "standard acrylic" do not filter UV. Perhaps if Mark is following this thread he'll jump in and help us clarify.

Full disclosure! I have no financial connection with Aardenburg but I do want to put in a plug for this service... it is well worth the modest membership fee.

Regards,

Paul

I submitted samples last
