At the photo lab, and the file I gave them...well it looks cool and blue on my computer screen, but then they printed it too yellow

It's an on going problem, and it does not end with simply colour calibrating your screen, because then you still have the different colour profiles, the shift from sRGB to ADOBE RGB is quite dramatic, so really need to pay more attention to what setting magazine and printer are working on, but in this case, at the lab, they worked in the same profile as me, so pick up a new set of prints tomorrow
