precise light and brightness
2006-03-07 by bill hansen1
I'll admit that I haven't used the Precise light slider when making profiles. Perhaps there's something about it I don't understand. Of the 8 profiles I've made for myself, 2 or 3 have needed slight (in two cases 5%, but in one case 10%) adjustments of Yellow. Of the three sample profiles I've made for other people, *none* have needed any color adjustment. It seems to me that it would be much more accurate to adjust color balance by using the individual color sliders than by trying to adjust "white balance" using a single slider. Does this match with the experience of others? And here's an even more important question - Brightness. All of the profiles I've made for myself have required slight (5-10%) increases in Brightness. And yes, the monitor is profiled with the Spyder2, and I let prints dry for quite a few hours, and I examine them with ample light which is balanced to be the same color temp as the light in which those prints will be viewed! Of the three profiles I've made for others, two have required 15% increases in Brightness and one needs a 10% increase. This is really not a problem at all, since those increases in Brightness can be included in the process of making the initial profile. Even making four versions of a profile, with brightnesses of zero, +1, +2, and +3 takes only about an extra 20 seconds during the profiling process. My own practice has been to use the Brightness slider to make those brightness adjustments - but I imagine that the brightness slider of the PreciseLight could be used in the same way. But I'm curious - do many others find that increases in brightness are necessary in order to match the monitor brightness? Bill Hansen
