Thanks guys. I thought I screwed up but I saw some density at around 40 minutes and I kept going. Next time I'll bump the temp to 30C - 35C and watch carefully, the rainy season makes my darkroom cold. Again, I appreciate the comments.
Very cool.... I can remember 50 minute dev times when I first started with Oriental Seagul and Novalith developer...... Many people thought I was nuts waiting that long. However, the color that can be liberated from some papers as a result can be quite different from a 'hot bath' that many use to get dev times between 3 to 6 minutes.
I agree with Andrew. You can get some pretty amazing results from prints that are in the bath for a very long time, and very different from those where you use a less dilute and warmer chemistry. Sometimes it's a thing of beauty to watch a print 'grow' for such a long time. Just get some good music and perhaps a good beer or glass of wine to keep you company. Try both ways if you want.
I find myself scouring through my negatives to find more potential images for lith. I'm definitely hook and loving this process - though, my wife not so much since I spend so much time in the DR. I'm hoping my X'mas present will appease the "home boss".
