Hi Paul,

I've worked with this paper enough to have a pretty good idea how the tones will behave with the subsequent toning steps. I use selenium first to reinforce the shadow tones, and to protect them during the subsequent bleach/thiocarbamide step. With MGIV, the highlights don't change very much during the bleach/tone stage, whereas with MGWT I have noticed a lightening of the highlights, so I do have to adjust the exposure to print them down a bit further.
