FAQ
How does CYANO simulate cyanotype prints?
CYANO simulates the cyanotype process digitally by modeling the physics of light interaction with iron salts. It accounts for the sensitizer's response to sunlight, pigment development via the Beer-Lambert law, and the resulting tonal curve, mimicking real-world photochemical reactions without actual chemicals.
What are the adjustable parameters in CYANO?
You can adjust the 'Sun' exposure time to control shadow detail, select from different 'Paper' types like cotton rag or watercolour, and apply 'Toning' effects such as tea or red wine. The app also allows for simulating a 'Brushed edge' and choosing between classic or modern 'Formula' sensitizers.
Does CYANO require a darkroom or chemicals?
No, CYANO performs all the chemistry simulation within the software. You do not need a darkroom or any physical chemicals to create cyanotype-style prints with this application.
What is the difference between CYANO and a blue filter app?
CYANO is not a simple blue filter. It accurately simulates how cyanotype is blind to red and green light, rendering colors at different brightness levels than a standard camera. This means bright yellow objects appear dark, and blue skies are rendered differently, capturing the unique tonal response of the actual process.
Does CYANO add watermarks or keep my photos?
No, CYANO prints your images at full resolution and does not add any watermarks or marks to your pictures. The app also keeps nothing and sends nothing anywhere, ensuring your privacy.
