For some time now I discovered the filmdev.org project on the Internet.
In addition to being able to find forced information from different films combined with different developers, it counts with images (almost always) of example so that you can get the idea of the results that you can obtain. Very good!
Obviously we also have the classic The Massive Dev Chart and its Massive Dev Chart Timer App for different smartphones, but the idea of being able to see the result with an example photograph I think is a lot better.
I take the well understood to put the “ recipes ” I’ve been uploading.
In the example, film Foma Fomapan ISO100 shot (forced) to ISO 800 and revealed with Rodinal 1 + 100 for 1 and a half hours.
