I believe it's an old Agfa method. Apparently Tri-X can be pushed to ISO 12000-25000. I have the article somewhere in my darkroom. If I find it, I'll send a pdf to anyone who might see some use for it. But I'm sure an email to Rangefinder could elicit the formula from them. I'm just going from memory on this, so there might be some inaccuracy, but overall, and with testing it's sound. The hydrogen peroxide has to be heated to 100 degrees. A lab hot plate is best, where the whole surface can held to within a 1/4 of degree of the set temperature. Place a 120 reel in a SS tank and then pour the heated solution to just below the top of the reel. You can't have the film touch the solution. After processing the film half way in the developer, suspend it over the HP vapors for a predetermined amount of time. It can take several minutes. Then return to the developer for the remaining amount of processing time. The rest is cookbook. I've seen images made with this method. the images looked virtually grainless with a surreal quality, as though somebody slightly lifted the curtain of night to let a bit a sunlight in. S.
