I’ve created a simple and efficient ratio calculator tool designed to assist with chemical mixing ratios for film development. It allows you to input a ratio, such as 1:5, and instantly calculates the required volume of each part based on the total amount of solution you need. For example, if you’re mixing 600ml of developer at a 1:5 ratio, the tool will tell you exactly how much of the concentrate (1 part) and the dilutant (5 parts) to use. This makes it easy to maintain precise proportions, ensuring consistent results in your film development process. It’s perfect for both beginners and experienced photographers who want to simplify their workflow.
