Hi Mac, The format for the two images is 4x5. The rule of thumb I heard was to "meter the scene at f90 and give it two more stops." This gives exposures of 1 or 2 seconds in bright sun with Ektachrome 64T (EPY). The few pinhole exposures I've made with 4x5 EPY were in the 16 second range. Naturally the slit exposure times can vary depending on the width and length of the slits; but I've found that this rule of thumb works well in almost all cases. (Also, I have a lab cross-process the EPY film to C41 and use the negative image to make color prints.)
