ADOX HR-50 135/36 – Bulk Roll with SPEED BOOST (30.5m / 100 ft)

Originally engineered for technical imaging, ADOX HR-50 has been transformed into a versatile black and white film through the use of ADOX’s proprietary SPEED BOOST technology, allowing you to shoot it at ISO 50/18° with standard developers.

This 30.5 meter / 100 ft bulk roll lets you cut and load your own 35mm rolls, giving you total control over exposure lengths and cost per frame—perfect for photographers who shoot often or love to experiment.

HR-50 features an incredibly fine grain structure and sharp resolution (up to 280 lp/mm!), making it ideal for street, landscape, and fine art photography. Its superpanchromatic emulsion ensures excellent tonal rendering, and it performs exceptionally well with color filters, including infrared applications.

Use with ADOX SNAP-ON gelatin filters or dedicated HR-50 developer for best results in portrait or filtered photography.
