When downsizing in Photoshop...

[JonHop]

Thanks for the in depth reply that helped a lot :). Just wondering about the 3 choice of settings when I downsize though, like when you have the 3 diff options, and you can choose nearest neighbour or one that says is best for smooth gradients and another one I don't remember, is there generally a best option out of those 3 or will it depend on the style/type of the painting?
