Thank you, Doug.
I'm aware there's a learning curve concerning everything you do in the lab. I would have to tame contact copying first to compare with the more friendly "reshoot in the light box" way. That's why I asked you experienced guys. I have already some mileage in the lab and yes, a notebook, is your best friend when you try to review a routine. I'm prepared to try again, and again, and again....
All the best,
Ricardo
