I agree with the above sentiments. Anyone can point you in a direction, but you still have to walk there by yourself so to speak. And maybe Gibson started out his journey with normal negatives and then found his own way towards the overexposed, overdeveloped negatives on hard grade paper. I have a lot of overdeveloped and overexposed negatives, but for my life of me, I can't get them to work for me, because my whole process is geared towards something else, even if I really love Gibsons photographs. And that, I feel is a major point; it is a complete process, not a certain film or paper. And as it is a complete loop of things, there's always a way to calibrate that process with another paper or film, given you have the stamina to see it through.
