2014年6月23日 · FG7 has never been published but uses NaCl formed by uses HCl and NaOH in the developer so in some ways is similar to Microdol/Perceptol. FG-7 is said to be based on Champlin #16. This has some credence since Edmund Lowe the founder of Edwal said that this was the only developer in Champlin's book that was worth anything.

My local photo-supply store says Edwal FG7 is discontinued--at least that's what they were told by their supplier. Has anyone heard anything about this?
