I have some high-quality RAW files of artwork that I've processed with some cropping, contrast adjustment, etc. I'd like them to be printed on metal at about 2'x3', which is about twice the size I get when the ppi is set to 240.
I've been looking at various options. I saw a roundup - it was a few years old, but it was the best I could find - which suggested that something called SmartEdge, then still in development, was the hands-down the best algorithm out there.
The test results appeared superior to Genuine Fractals, which is (or was) a paid service.
Does anyone know about these? Whether they can be brought into Adobe programs or only used via stand-alone software? But most importantly, what is the most effective algorithm?
