Re: Lightroom CC 2015 (Mac) Print Adjustment sliders

Let's assume you meant in Lightroom (and by the way, are you using an older version of Lightroom because Brightness has not been a slider for a couple versions).
Anyway, the basic approach is you get the image to look how you want it in Lightroom, and then send it to QTR. In Windows that involves exporting as a TIF and manually printing through QTR. As I understand it, in Mac you're going to want to print via Roy's Print Tool; I think there are issues printing directly via the Mac printer drivers. Mac folk can explain.
You can adjust midtones and shadows in finished prints through QTR, but I prefer to get it right in Lightroom and make no further adjustments in QTR *except* ones relating to curve blending. For this to work, it's essential that you soft proof in Lightroom so that you get as close as possible to "what you see is what you get".
For all of this to work, you need a properly calibrated monitor, and you need to be sure that your QTR curves are properly linearized.
I hope this helps.
