Adding to the modern articles on the process in the resources section is an exposure guide for plates sensitized with iodine and bromine and developed with mercury. Submitted by Irving Pobboravsky, who notes that because every worker’s situation is different it should only be considered as a starting point, but it is just the sort of resource we seek to gather for the readers of this site, many thanks to Irv.

Additional notes from Irv:
EI = Exposure Index

the table at the top is for an exposure index (ISO) of 0.05; the one at the bottom is for ISO 0.10.
