Thanks Orsan.
Does that mean that if I print it to a file using the calibrated profile the printing lab will use that and my pictures will come closer to what I want ?
From what I managed to learn up to now the paper used counts too in the outcome.
So if I want to see what my pictures look like I have to have the printer's profiles like the one's I have for my local printer.
What I see in Lightroom in the profiles window, a few that are my printers profiles with some codes that I suppose mean quality and /or paper type and 3 display profiles that I don't have a clue what they mean.
I'm a bit(gross understatement) confused, I must confess
