I put a piece of a negative with a 1.08 (Zone VII) density into selenium toner d iluted 1:9. My goal was to raise the density to 1.30 (Zone VIII). I agitated it in the solution (at 70) for 10 mins. After I washed and dried the film. Then I r ead it with my densitometer and it still read 1.08.

I then put the negative into a 1:3 dilution of selenium toner and did the same: 10 mins. in selenium, wash, dry. The density was still unchanged.

Then, I put the negative into straight selenium toner for 10 mins with agitation . Afterward, the density was still 1.08.

My film was HP-5+ and it was not hardened. I guess HP-5+ does not tone. Any sugg estions?
