Well, I wanted to see with my own eyes what all the fuss is about. I've been printing exclusively with MGIV RC till today. I made my first prints (All 2 of them) on MGIV FB. These are my impressions:
1) The print looks very beautiful, deep and rich. The FB print required a half grade less contrast with the same exposure to match a previously developed RC print.
2) Now I really understand what curled paper looks like!
3) It's a loooooong process. I decided to follow Ilford's Optimum permanence sequence with selenium toner.
4) I use my Jobo for all my RC print development except toning. I decided to develop and fix the FB in the Jobo then continue the sequence in trays. I wish I could run the entire sequence in the Jobo. I have enough drums to make this very efficient.
5) I was VERY surprised with how warm the print color is. The base is creamy and the blacks are warm. I tried to cool the print down with 10 minutes in 1+19 selenium but it made little difference.
6) The first print shows rib marks running along the width of the paper. These clearly result from the ribs inside the Jobo drums. 4 minutes in a dry mounting press cured the curl but not the marks. The second print didn't show any rib marks. The first print was dried very quickly in an RC print dryer, while the second one on a drying screen overnight. It looks like slow drying does away with the rib marks. I was very glad to find this.
Now I'm wondering why not run the entire Ilford Optimum permanence sequence in the Jobo with the exception of the final wash? Has anyone done this? Are there any issues to consider when using selenium toner in a Jobo? Also, how do I get a print that approaches the colder blacks of MGIV RC? Will more concentrated selenium toning do the trick?
Thanks,
Luigi
