I'm thinking of having a couple of metal prints (from BayPhoto) made for an upcoming art show. I've never done any metal prints before, so I have a few questions. First, how much sharpening should I use? Anything else in particular I should do in photoshop to get the best quality print?
I'm also debating between going with the White High Gloss, or Sheer Glossy finish. I'm leaning more towards the Sheer Glossy, but having never seen either in person, I'm just not sure which would be best.
Here are two of the prints I'm considering doing in 20x30 for example.
