SPUR HRX is a developer for all black-and-white films, primarily optimized in view of achieving the highest possible fineness of grain. With most films, SPUR HRX is substantially more apt to exploit speed than its predecessor HRX-3 New. Contrary to other fine-grain developers, SPUR HRX delivers high sharpness and outstanding detail. Another advantage of HRX is its superbly sophisticated tonality due to the ideal, linear gradation curve gradient; the middle tones are thus very subtly differentiated even in soft development (N-1 to N-3), thus preventing dull or flat results.
Supplied as liquid concentrate, 100ml Part A + 100ml Part B.
