Apply the "If it quacks like a duck..." method. The negatives sound overexposed, and, yes, the meter could be off 4 stops for whatever reason. I assume an operating room is *bright*, especially the "business" area where all the lights are pointed. 1/4 second at f/4 would probably be way overexposed on Tri-X, IMHO. An adjustment in development can probably save this, but go by what the negatives tell you, not by any suppositions about the prior history! Good Luck.(posted 9137 days ago)
