ADOX HR-50 is based on a superpanchromatic B&W emulsion commonly available for technical purposes, featuring ultra-fine grain, excellent sharpness, and very high resolution. The film's speed is enhanced to ISO 50/18° using ADOX´s new unique SPEED BOOST- technology, especially when paired with its recommended dedicated developer, the ADOX HR-50 Developer.
Thanks to its high resolution, sharpness, and fine grain, ADOX HR-50 is especially well suited to landscape, architecture, and travel photography. Among all current B&W negative films on the market, only ADOX CMS 20 II has significantly finer grain than HR-50.
Its extended red sensitivity means that ADOX HR-50 can be used as a near-infrared film. To maximize the "infrared look" (green leaves become white), a strong IR filter which blocks visible light below 715 nanometers is recommended.
