TF-2, the fix I've shown before, isn't very effective at fixing tabular grain films.
In this video I demonstrate the making of Agfa 304, a rapid fix better matched to tabular grain films such as Delta and TMax. The advantage in this formula, and the reason I use it, is the use of chemistry that is still available in UK.
In the video I say the wrong amount of potassium bisulphite! It should be 20g, not 10.
At the end of the video I test regular fix against this rapid fix so we can see how this formula fixes tabular grain film faster.
