Re: (NNG) Color vs B&W ... and Pan-X

Bottom line gentlemen is that as a professional you knew what to expect from your film(s) and you used the film that best suited your needs, and you always carried higher speed ASA films in case of problems.
If you shot Kodachrome 25 you backed it up with K-64 and for B&W Panatomic-X for good static shots but Plus-X for all around with Tri-X as your back up.

After spending an afternoon at the CRRM and examing negatives of Bob Richardson and others, the film of choice was Tri-x on better than 80% of what I saw and that was a small amount when one considers what they have.
