Hi. I recently took out my 4x5 crown graphic after putting it away for some years. I set up a darkroom using equipment donated by an old friend. I was using ilford hp5 400 speed film from a sealed box that expired 4 years ago. I developed my negatives in xtol 1:1 in a stearman developing system. My negatives came out almost black as pictured below. What happened?
