I actually did just that with a sheet of 4x5 film that had been in the developer a few minutes. I was developing with IR goggles and noticed the sheet was blank. I wust have forgot to pull the darks slide. For amusement I slapped the sheet emulsion side onto the Gralab timer for about 3 to 5 seconds, thinking the numbers wound print. However the sheet stayed perfectly clear. I have heard that film is less light sensitive after it is in the developer which is counter intuitive but people do develop by inspection after all.
