Response to HP-5 Developer

from Michael D Fraser (mdfraser@earthlink.net)
HP-5+ has a speed of 200 in PMK (15M@68F) and produces excellent results. Some other developers, like Xtol, may produce a bit more speed (about 1/3 stop) but at the expense of increased fog. If you need a speed close to 400, you may want to use TMY which has a speed of 320 in PMK and works well. ID-11 and D-76 are the same developer. When used undiluted, both will result in a soft, 'fine grain' negative with poor acutance.
