Dan, most papers sold today contain small

I thought I should confirm Freestyles claim of DI
free Graded papers so I tested an Arista Gr.2 RC
with Na2CO3. Zero indication. Perhaps the agent
involved was not or was so little activated by a
carbonate as not to show. Perhaps very minute
amounts, none even, are present. So the
Zero indication.
So, from my reading of S. Anchell I'd suppose
speed enhancement is the reason for the small
amount of DI. If not for altering the contrast
what other than altering the speed? Dan
