I'm shooting 4x5 and will be developing in pyrocat-HD using a unicolor tube on a uniroller for silver enlargement from a color head. I'm hoping to use times at 75 degress F as that is the most common temperature at my house. Glad to know about the speed settings as I'm planning to use your FP4 time for my initial testings at 75 F after I order my chemicals.
Also, I'll be in Houston/Galveston the weekend of August 8th. If you might have some free time to go shooting out on what you people who lack the ocean call a beach (that's my virginian talking out) please send me an email or PM. I'll be out on the island all day on Saturday and most of Sunday.
