The process of film development might seem daunting at first, but it’s a journey well worth embarking on. Start by loading your film into a developing tank in a completely dark room or changing bag — so no light hits the film and ruins your precious photographs.
Once the film is safely in the tank, mix your developer. The developer is a chemical solution that reacts with the exposed silver halides in your film, reducing them to metallic silver and creating the dark areas in your negatives.
After the film has been in the developer for the recommended amount of time, it’s placed in a stop bath. The stop bath halts the development process, preventing the film from becoming overdeveloped. This could be as simple as a running water wash (and this is what I prefer these days, over the over-priced vinegar mixes).
