    Dedicated LF developers

    There use to be many developers dedicated mainly for LF film. Kodak D 19, Gevaert G.201 are known for their brilliance, G.215 is a soft working developer,... They are all quite fast working which was beneficial when tray developing was the norm. They are not of the fine grain type but that shouldn't be priority when shooting LF. I wonder is there still a reason to favour these old formulae?

    D19 is a particularly high contrast developer, I used it for b&w reversal for that very reason. I don't think it is specifically "known for it's brilliance" or ever preferred for LF use ?
    Where is it suggested that it (or any of the others) are "LF" developers ?

    In one of the books on photography I have, from 1960.

    While some developers are more suited to MF and LF films because they tend to emphasize grain I would say that it is erroneous to characterize them as "large format developers." In fact this idea turns the common definition of developers on its head. What is usually done is to say that there are general purpose developers and those more suitable for miniature camera use.

    The well known Kodak D-72 was even a so called universal developer. It could be adjusted by the dilution to paper, sheet film or roll-film. But for small formats (120 or 135) it was too contrasty and grainy, for real large formats like 4 x 5" or 8 x 10" it was o.k.

    How a developer is used also has an effect. DK-50 would be considered a MF/LF type developer. However when diluted 1+4 with the Kodalk concentration restored to its original concentration it is an acutance developer suitable for 35mm film.

    To be more exact there is a capater in the book I'm referring to about tray/dish development. Roll film development is covered in anothe chapter, giving formulae for D76, Various Agfa developers (8, 14, 15, 17,...), Atomal, Adox MQ, Be-Be, Windish 665, Sease 3, etc, and explainig their characteristics.

    So putting a developer in a tray somehow makes it different? From the little that you say above the chapter appears to be more about development technique than any thing else.
