Pulling Ilford HP5 Plus 400 ISO film to 12 ISO. Possible?

Stone,
if you can get the darkroom cook book.
Although, in my opinion, being poor value - too expensive and not that much information - there is some information you will not find easily elsewhere. It is worth buying for future reference. You will find information on reducers and intensifiers, where to buy and if you are up to mix them yourself.
Not on the top of buying priorities, but unique (?) and nice to have.

Hi
By mistake I exposed Ilford HP5 Plus 400 as ISO 12 :-(

Do you have any idea how to rescue that film? It means how develop it.

greetings

Not an expert by any means but my best bet is to use very diluted rodinal (if you have any) something like 1:400 and develop by inspection. If the developer loses strength before the desired development level, add fresh 1:400 solution.

You can always use a reducer afterwards.
