I have a LF lens I am setting up for portraiture with a Calumet 4x5 monorail. T he lens optics are ILEX, 216 mm (8.5"), max aperature is f 4.5, time from 1 sec to 1/150 sec, with B & T settings. The shutter is an ACME #4, manual cocking sh utter, and a manual cocking flash synchronization control. All is well except u nderstanding the flash sync dial with 4 settings. The dial has a number range a nd settings of 0,5,10,23 and a corresponding color dot of black, red, blue, and yellow respectively. (The lens is at home, I writing from work and may not be e xactly stated) All four settings consistently fire a strobe from the 2 prong co ntacts. My question is how do I use/interpret this dial next to the sync contatcts? Are the settings delay after shutter full open?
