Equal dilution will result in equal speed as well as about equal development times. HRX-3 may to a very slight extent work more softly and more sensitively, the development time for the same gradation possibly having to be somewhat extended. You will find information on processing in the attached developing chart. The times indicated there have not yet been tested in HRX-3 but for a few emulsions (marked yellow). The other times have been taken from the HRX-2 developing chart and are supposed to be approximate values until we supply more data. The times indicated are valid for the development of 35 mm and roll films. For sheet films developed in trays, tank or rotatory development reduce these times according to the circumstances. The minimum amount of concentrate needed for one 35 mm film is 8 ml. Lower amounts might work but have not yet been tested by us.

<strong>Data</strong> <strong>Sheet</strong> <strong>On</strong> <strong>SPUR</strong> <strong>HRX</strong>-3 Professional<br />
<strong>SPUR</strong> <strong>HRX</strong>-3 is a development technique for all black-and-white films that is primarily optimized in<br />
view of achieving the highest possible fineness of grain. As usual for fine-grain developers, <strong>HRX</strong>-3<br />
cannot for the most part fully exploit speed. In contrast to other fine-grain developers, it does however<br />
deliver high sharpness and outstanding detail contrast. Another advantage of <strong>HRX</strong>-3 is its superbly<br />
sophisticated tonal values due to the ideal, linear gradation curve gradient. The middle tones are thus<br />
very subtly differentiated even in soft development (N-1 to N-3), and consequently will not entail<br />
washed out or dull pictures. This has been a disadvantage of many conventional developers, which<br />
show a gradation curve sag in the middle tones. Apart from that, <strong>HRX</strong>-3 shows a slight flattening in<br />
the shoulder area, as a result of which the highlights will remain easy to copy at all times.<br />
Features: Long life, fineness of grain, exposure latitude, and the extent to which gradation can be<br />
controlled (zone system suitability) of <strong>HRX</strong>-3 have all been substantially improved in comparison to<br />
the predecessor <strong>HRX</strong>-2.<br />
The development features of <strong>HRX</strong>-3 are comparable to those of its predecessor <strong>HRX</strong>-2 with the<br />
exception of the improvements mentioned above. Equal dilution will result in equal speed as well as<br />
about equal development times. <strong>HRX</strong>-3 may to a very slight extent work more softly and more<br />

Developing Chart <strong>SPUR</strong> <strong>HRX</strong>-3<br />
The values indicated in the chart are valid for a developing temperature of 20° C for negatives<br />
with an average Beta of ca. 0.6. Agitate by tank inversion every 30 seconds. We recommend<br />
inverting the tank twice right at the beginning, i. e. straight after filling. At exposure you must<br />
comply with the ISO figures as indicated in this developing chart, and NOT the requirements of<br />
film manufacturers.<br />

The times indicated here have not yet been tested with <strong>HRX</strong>-3 but for a few emulsions (marked yellow).<br />
Since speed and development times applicable are approximately the same as for <strong>HRX</strong>-2, the other times<br />
have been taken from the <strong>HRX</strong>-2 developing chart. They are supposed to be approximate values until we<br />
supply more data.
