Hi, Does anyone use ILFORD HP5 Plus sheet film for pinhole photography? If yes, I need advice.
The manufacturer has supplied my with a reciprocity failure chart that end with 35 seconds metered time, transforming into 200 seconds actual exposure time. On my last shooting meter reading was 2 minutes. A wild guess was to compensate for 5 minutes, but both negatives came out quite underexposed. The reason I use HP5 is that in Europe it is: A) cheaper than Kodak B) An excellent film for (almost) any photographic purposes C) Can be generously pushed and pulled D) I juts like it Do any of you HP5 users (assuming there are a few worldwide) have any personal experiences to share? I need corrected exposures times, let's say from 1 to 5 minutes. Erich
