[pure-silver] Re: Agfa APX 100

Hi there,

this might be me again making one of my traditional mistakes but I also use _agitation_ to control the contrast of my negs ?

So I kind of agree with Richard saying: "Contrast is a matter of development", but in this case I fiddle the agitation - more agitation makes contrasts sharper and YES you can easily develop to get "blown out highlights".

In the days of yore, before The Rains came there are/were charts giving you a "lambda" value of either .55 or 0.65/0.75 which was a contrast measure. These were intended for peole with either condenser based or colour head enlargers?

When you had a colourt head, you needed "harder" negs and for condenser you needed softer ones (9,45-0,5 lambda).

Also I feel that rodinald does not only compensate "a little bit" but actually manages quite a lot, at 1:150 or 1:300. But then you need time for developing for an hour r so.

Love
Snoopy

I usually get better contrast out of Rodinol, but I also use ilfotect-hc (hc110), D-76 1:1

    characteristic contrast range of film due to the distribution of

    different from one to another pictorial films. One sees it when
    comparing pictorial film to commercial or lith film. If the contrast
is too low increase development.
