- Low contrast 50 ml and
- High contrast 50 mls.
- You can mix the high and the low contrast sensitiser to make a med range contrast.
Mike Ware developed this“Simple’ sensitizer. It contains no toxic dichromates or oxalates, making it safer for children and the environment. The ‘one-bottle’ sensitizer is faster than an average ‘Classic’ two-bottle formula, but still slower than ‘New’. It has excellent tonal separation with a high Dmax of ~1.5 and it can provide an exposure scale varying from 2.7 to 1.8 depending on the sensitizer formula, so the contrast can be fine-tuned to match widely differing negatives – an innovation which has not been possible with traditional cyanotype.”

This process requires no other chemicals, can be exposed in sunlight (UV) and developed simply in water. No other chemicals are required. Cyanotypes provide a beautiful image in stable Prussian blue pigment. The image colour may be easily modified by a variety of toning agents.
THE CYANOTYPE HISTORY
Sir John Herschel’s traditional cyanotype process, now practiced for 166 years, became known as Blueprint, the first reprographic process. It is one of the oldest, simplest, safest, and cheapest alternative photographic process. Mike Ware developed the New Cyanotype in 1995 renown for the beautiful extended tonal range and now Mike has offered the world the Simple Cyanotype which offers range of contrasts.
