ADOX HR-50 with SPEED BOOST 135/36

ADOX HR-50 is a superpanchromatic black and white film rated ISO 50 on a 0.1 mm PET base. SPEED BOOST is ADOX's own treatment that brings the emulsion up to ISO 50 and lowers the gamma, so a stock built for technical work handles ordinary subjects at normal contrast. Grain is extremely fine and resolution runs to 280 lp/mm at an image contrast of 1000:1.

ADOX recommends its own HR-DEV developer. For portraits ADOX names FX-39 II as the alternative.
