    Selenium Toning at greater than 1:10.......

    ........with Ilford MGIV FB. Does anyone do it and does it produce a greater density shift or shift in color? Thanks

    I'm assuming you mean stronger dilution? I regularly tone MGIV FB at 1:9 for 6-8 minutes. It cools off to a very nice bluish purple tone and the shadows are increased by about 1/4 grade. I've never tried it at 1:5 or 1:3, but would be interested to hear results.

    Yes, Brian, I worded that poorly, I meant stronger dilution.

    I usually use 1:7 and have about the same results as Brian. Nice deep blacks.

    I've gotten into the habit now of printing slightly soft on MGIV and slamming it in selenium as I mentioned above. Not only does this greatly protect the print (much more than 1:20, 1:40 dilutions for a minute or two) but it also takes the tone of the paper to a true neutral tone, slightly cool. Great stuff!

    I went ahead and mixed up my last batch at 1:10---if I'd had more on-hand I would've experimented a bit, guess it'll have to wait til the next fresh bottle.

    Do all of you use the Kodak rapid selenium toner? Or have you tried the Ilford / Harman version too?
    I've only gone as far as three minutes at about 1:5 dilution, and now I'm curious to see what happens at 6-8 minutes.

    Thomas,
    I've always used Kodak's selenium toner, but just never stronger than a 10% solution. Are you printing on Ilford's MGIV FB, if so, how much of D-max increase do you perceive with it. Currently, at a 10% strength with MGIV FB, I'm not really having to account for the important shadows in printing, meaning, I can print them the way that I want, and after toning the shadows are strengthened with the detail in those shadows still satisfactory. I was wandering if going stronger on the selenium for more of a color shift, if I would then have to go easier on the shadows in printing and then rely on the Dmax increase in toning to get them where I wanted them to be originally.

    I think that the Harman selenium toning gives me shadows that are approximately 1/4 stop denser than untoned. That's using Ilford MGIV fiber. And I perceive a tiny color shift towards a hair more neutral black. I just haven't tried extending toning times to something like 6-8 minutes.

    I've never tried KRST stronger than 1+9 with MGIV FB but now I'm curious. MGIV FB is fairly resistant to pronounced colour shifts compared to some other papers (Oriental VCFB for example), but I'm thinking a test is in order. I'd like to measure the reflection densities also to try to quantify the d-max increase.

    My understanding is Harman Selenium is very similar to, if not virtually the same as KRST.
