    Were these developed to the same CI?

    Interesting. To my eye the Beutler seems "sharper," probably higher acutance, but perhaps a little grainier.

    You won't see the true difference with a scanner, unless it's a drum scanner or an Imacon.
    You will see an approximation of the grain. You need a true 4,000dpi optical resolution to resolve grain.

    On screen it is difficult to tell the difference but I think that the Beutler ones look slightly better.

    This would fit with my conclusions as I standardised many years ago on Thornton's two bath which is a derivative of the Beutler formula.

    Besy,

    Interesting results. Beutler is a very good dev.

    Neofin Blau (same as Willi Beutler's) has been my long time favourite developer. Now my stock is running a little low and I am considering of mixing my own as this is a very simple developer.
    I have been using quite a bit of Rodinal as well. In real life terms as in printing Rodinal delivers grainier negatives. High speed films do not come out very well in Rodinal: grainy and low contrast.

    Also better internal contrast.
