Film Photography for the 21st Century
Meet the Chromabox-4 by Midtone Machines. The most flexible fully automatic film developing machine on the market.
Process Capabilities
Comes pre-programmed with developing recipes for B&W, C41, E6 and ECN2 processes
Fully flexible graphical interface allows for user-programming of any number of custom recipes, each with up to 255 steps
Recipes are stored on a standard SD card, which can be moved between multiple machines
Your imagination is practically the limit, B&W reversal, alternative processes, film souping etc. are all possible!
Chemistry
6 independent chemistry channels, all fully programmable to be whichever chemical is needed
Chemistry is drawn into the machine from external tanks, there’s no limitation to the size of chemical container used. Film labs can draw chemistry from bulk containers meaning less labor and mess!
After every step you can choose where the used chemistry goes, back into the original container, to a waste container, or to a completely different container for replenishment or special disposal (e.g. silver recovery)
Automatic line-flushing processes between steps minimizes the chance of cross-contamination and extending chemistry life
Temperature Control
Fully automatic temperature control of each chemical with a resolution of 0.1ᴼC (0.18ᴼF)
No cumbersome water bath required! Every step can be programmed to a different temperature if needed
No heat-up or cool-down time required when switching between processes. For example B&W film could be processed immediately after C41 without waiting for the machine to cool down!
Maximum process temperature of 45ᴼC allows for processing of ECN2 film at the correct Kodak-specified temperature
Chemistry temperature in the film tank is directly measured and controlled to ensure consistent results
Film Capacity
Each step uses 500 mL of chemistry, meaning less chemical use and waste compared to hand developing
Each tank can hold 4 x 135, 2 x 120/220, 6 x 4x5 or 4 x 5x7 rolls/sheets of film per cycle (sheet film requires 3rd party film holders, available separately)
Agitation speed is programmable to 3 different levels and either single-direction or bi-directional depending on your needs
User Interface
The Chromabox-4 is programmed and operated using a large 4.3” color LCD display and a 5-direction navigation button (much better than using a touch screen with wet hands or gloves!)
Recipes are programmed or edited using an intuitive and flexible spreadsheet-like display
A maintenance screen allows the user to monitor every sensor and control every valve and heater manually when troubleshooting and performing maintenance
Temperature calibration values are user-programmable to allow for fine-tuning and greater accuracy
