Our new paper tube boxes are made of solid and thick carton, which provides a sufficient isolation to store your film in a dry place without any risk for the emulsion. If you plan to store the film for a long period of time or live in a humide environment, we recommend placing it in a ziplock bag inside the fridge. Make sure the bag is perfectly dry inside and well sealed.
ATM400 develops like any other black and white negative film. You can find below the times and dillutions for most common developer.
For other developers and pushing/pulling processing, we recommend following the chart of Ilford HP5+. More information on the Massive Dev Chart.
Yes you can! We recommend pushing ATM400 up to one stop (ISO 800). Beyond, contrast might increase too much and risk of loosing shadow details.
No, at the moment we use recycled film canisters so our film doesn’t come with DX code. When shooting ATM400 with point and shoot camera, if you can’t set the ISO manually the camera will most likely expose it at 100. You can either add +2 stops using the Exposure Compensation feature, or pull the film during development. Please note that pulling film may decrease contrast.
