I've used it. Very tricky to use (my prints were 16x20, so that likely played into it). It does give a silver, reflective look. As far as adjusting, from what I remember it is either silvered, or it isnt. The "isnt" parts were more of a brown tone (the toner exhausted before silvering all the black in the image.). Tim Rudman's toning book has lots of information (wish I'd had it back when using the halochrome!)
