developing with PMK

i have just finished reading the book of pyro. i was unable to find any referance to the min number of sheets of film that must be developed at one time. or can you just develop one sheet or must you have at lest 4.
thanks

there's no minimun sheet quantity to develop

The only problem is that is a time consuming process... and you'll spend more developer because it's quite reccomended to use fresh soup every time.

Also, you get calibrated with some many sheets of film per liter of developer. I'm calibrated for 6 sheets of 5x7 per liter. If I only run four sheets, then I add one dummie sheet that has been exposed to daylight and that gives about the right 'loading' on the developer as the two missing sheets.

The answer, yes you can do one or more sheets.
