Hello :

I did post this one another forum, but did not get manyh replies thus wish to post the same questioin here -

I am seriously considering the D3s - 12MP would be sufficient for the most part, but there could be times when I need to print 30 x 40 inches.
Wondering if Master "Up-rez-ers" and Master "Printers" can share their techniques that go beyond using Adobe's bicubic, bicubic smoother and plug-ins such as Blow Up2, etc.

Wish to learn the special / "dark magic" of enlarging and preparing files for fine art printing.

Undertaking workshops is not an option at present as I am not based in the US - If there are books ( I have checked amazon.com ) that detail techniques and workflows, I will be happy to purchase them.

I await your replies.
