You use D76 for paper?

Since paRodinal is just like real rodinal, the comments from the ORWO FORMULAE book could apply- and here is a quote:
[SIZE=2][FONT=Times New Roman]"R 09 can be used even for developing photographic paper. In doing so, suitable papers show a warm tone.
Ratio of diluting : Contrast
1+5 to 1+10 : Normal
1+20 : Soft
1+30 to 1+40: Extra Soft (especially for two-bath developing)
Attention! durability and utilization of highly diluted R 09 developer are less than those of special paper developers."[/FONT][/SIZE]
Some papers, notably those marked 'rapid' RC types have hydroquinone or some other developing agent incorporated in their emulsions. As such they often need only a strong alkaline bath to start developing. These paper often show a rather warm tone when subjected to such alkaline activator baths.
