    Yes - If you read Anchel - it makes sense - the weaker developer (and longer time) has more time to work on the shadows while becoming exhausted in the highlights - this causes more development in the low zones bringing up the film speed.

    I don't necessarily equate very dilute with weak.
    For example Beutler's and FX-1 are by nature very
    dilute carbonate activated compensating developers.
    They are not weak.

    D23 is a weak developer even though at a 1:3 dilution it
    has four times the amount of metol per liter as FX-1;
    a sulfite activated developer. Dan
