The most common misconception is that simply overexposing and overdeveloping Tri-X in Rodinal would give the Ralph Gibson look. As always, it's about the printing stage and those people who are simply scanning just can't wrap their heads around it. He printed on the hardest grade Brovira and that doesn't exists anymore. Adox MCC110 would get you close, and so will the new Oriental Seagull. He also exposed differently, as he exposed for highlights, not concerned about shadow detail.
