A 6'' touchscreen is placed on top of the enlarger and a 3.5 inch display on the developer system. Users will use these two displays to control the systems and adjust their images. Users will also receive operational instructions through the displays. So it is critical that the software system is simple to understand for both novices and professionals. And at the same time, the UI system is flexible for more advanced users to have as much control as possible.

The operation processes are determined by the design of the whole system. In order to provide clear instruction and powerful tools for users to make a print, I need to understand the workflow and discover the key features users are looking for.

So I first simulate and analyze the process of using the system to print an image from a black and white film. And then I developed wire frames based on the user flow. Later on, with the help of Adobe XD, I built a prototype for potential users to have a test and provide feedback on the software.
