lightroom and colour profiles.

[davecropp]

When I convert a file to a different colour profile in Photoshop it asks me if I want to apply it RELATIVELY OR ABSOLUTE OR PERCEPTUAL.
When I output in Lightroom it just applies the profile with no choiceS. Now it's not a problem as the files print OK when I send them to the lab , but does anyone know what settings Lightroom chooses to use?

LR is just being more honest than PS. The fact is that when converting from one working (matrix-based) profile to another the rendering intent will always be Relative Colormetric, even if you have selected Perceptual in PS. Since no choice exists, there is no need to offer one. Only when converting to a profile that contains LUTs (like a printer profile) can the rendering be Perceptual and in the Print module you do have that choice.
