Digital BW, The Print

Last night I had a long conversation with an interesting chemist (and 
amateur photographer) who worked for Eastman Kodak long ago.  He has 
just purchased an Epson 1800 and he said that he liked 
the "consistency" of digital photography.  He told me that chemists are 
always concerned about the use of "natural" materials like gelatin, 
which, of course, Eastman used extensively.  Natural materials, he 
said, tend to be inconsistent.  Their solution?  For many decades 
Eastman had their own herds of cows so that they could control the feed 
and improve the consistency of the gelatin taken from hoofs and other 
body parts.

And we thought we had problems with ink batches and ICC profiles.
