Thank you so much Jason. Today I felt like Monsieur Daguerre himself!!!! I am totally excited.
The difference was as you said: the double layer of Rubylith. I had it in the hot sun for 1 hour and 40 minutes before fixing it and this it what came out (picture attached)
Thanks for your help. This was spot on advice.
