Photographer's Formulary DiXactol Ultra Film Developer is a unique developer of special interest to artists and photographers producing monochrome fine prints, yet it is also uniquely tolerant and easy to use. It has four main distinguishing characteristics.

It produces the fullest palette of richly graduated tones, especially in the holding of translucent and delicately drawn highlights particularly resistant to "blocking up" at high exposure levels.

At the same time, shadow detail and separation is nursed up to unusual levels. Printing is likely to need significantly less burning in, in landscape skies for instance, and graduation is likely to be markedly superior in these burned-in areas. Discriminating workers appreciating the fine separation of tones should find this a satisfying developer.

Secondly, the sharpness of images produced is remarkable with outstanding acutance. The maker believes this to be the sharpest developer of any commercially available solution.

Thirdly, unlike normal high definition developers, the grain appears as fine as standard developers due to a special grain masking effect. (Photographers requiring the finest grain of any developer at a slight expense of acutance compared to DiXactol Ultra should use DiLuxol).

Finally, all films (with the exception of adapted document copying films and ultra high speed films) can be developed together in the two bath option, regardless of film speed or make, for about the same time, and with great tolerance of exposure and processing temperature, to produce printable negatives.
