I forgot to add that Ciba paper comes in three contrast grades, normal=20
(which is like grade 4-5 B&W paper,) medium (which is like grade 2-3 B&W=20
paper,) and low contrast (which is like grade 0-1 B&W paper.)

You can get the inexpensive RC paper only in medium contrast. You can get=20
the polyester paper in low, medium, and normal contrast with the exception=
=20
that you cannot get 20x24 polyester paper in medium contrast!!! You can get=
=20
20x24 polyester in low or normal contrast. For medium contrast, you can=20
only get RC paper!!! Write Ilford and complain!!!

Printing Cibachrome is not difficult. But you should not jump in too deep=20

CPM paper, either glossy or pearl. It is the least expensive paper and the=

medium contrast emulsion is Ciba's latest and best emulsion. I use this=20

Give it a try...
