I overexposed some 4x5 HP5+ by a stop and need some insight on pulling it. I usu ally shoot 35mm from an EI of 320 to 400 and develop normally in xtol 1:1; I hav e found 320 a better rating lately in 35mm with the xtol. At 200 I'm up in the a ir. I'll probably dilute xtol 1:2 or 1:3 since the film is larger. My normal pro cessing temp is 72 deg. I shot the film figuring an EI of 400 and overexposed it with an incorrect meter setting.
