Steve: Your further, and very much appreciated, more detailed explication would be foolish for me to ignore, and not give a try. I'm not certain that my (Dell) monitor's brightness control will permit me to dial down to the extent required, but what can I lose in trying (except the need to reset if it doesn't work)? It just took me so long over time to evolve my current practice (and settings) that I am (possibly understandingly) loathe to mess with it all. But I will. Thanks again. And also to Jeff, for so much more to think about and experiment with. Jim
Steve: My present established brightness level on my Dell is 36. Bringing it down to its minimum (of zero) I regret still doesn't reduce the brightness level sufficiently for me to employ your otherwise highly logical and attractive solution. Many thanks again. Jim

...The reason that Lightroom 4 added the Brightness and Contrast slider in the print module was because for some people, there may be limited ability to darken the display output. Certain iMacs screens for example can NOT be dimmed down to the standard 140 cd/m2 even using hardware based display profiling. For people who simply can't get their display and print viewing luminosity to match, the use of the Brightness slider is offered. It's useful in those limited situation because then you don't have to alter the image settings in Develop, you simply apply an adjustments at print time.
This, Jeff, is of course my situation (and problem) exactly. When I find the appropriate additional brightening level in LR 3.6 to match in printing the tonality of my preferred monitor image, I save that image (with a separate designation) with the Export function. I am still struggling with being able to achieve these results with LR4 in combination with QTR. However, in spite of your patient guidance to date in this regard, my level of comprehension is regrettably lagging behind. I still don't understand
Quotewhat very specific steps I must take. But I haven't yet given up.
Jim and Jeff
I had this problem with my iMac and was able to get the luminance down to 100 cd/m2 and lower if needed. The solution was to put a neutral density filter over the monitor screen, I used a sheet of Lee filters #298 0.15ND (-½ stop), and then profiled the monitor.
