   I'd say you did pretty good with this. I expose my cyanotypes for ten minutes and I get a pretty good exposure.

   @leisuresuit : Thank you, for all. I made a chart with the same image that I expose each time 10 seconds more, and the best result is around 3 minutes. But it depends on the sunshine that day. With my transparencies, it goes faster than average. I do not understand why. That's why I always overexposed my cyanotypes before doing a real exposure test. It should be OK now, (but there won't be many days with lots of sun where I live)... Thanks again anyway...
