Samples as requested. A cousin's wedding that i was helping out in.
My fren's point is that when he zoom in a couple of times...becomes rather grainy n pixelised. n when trying to use e sharpen feature in photoshop...he cannot sharpen at all.
I'm assuming that's heavily reduced. Are you shooting at full 6MP? If yes, then there's definitely a lot PS can do. If he said he can't sharpen it, then he needs to go back to Photoshop basics.
