I've had it with this g..d..mn forum or rather, Jive. Now, every time I reconnect, I have to sign in. WTF! So far as the IRE connection, if you set up your monitor defining the lowest visible detail in the blacks then set the range to be defined by the whiteness you actually want, you wind up with 0 to 100% as the range of values. (Forget about the sync pulses!) I realize this is all over the map with LCD monitors because they have a brightness value far higher than a crt and certainly paper white. But even b&w crt's from the 40's and 50's can blow you out. So I set the brightness value to 100 (during calibration), use the black clipping point as an absolute minimum and adjust contrast and brightness to achieve a working gray scale that approximates the IRE range. Since it is in terms of a %, to say 100 IRE as an absolute brightness is incorrect. But I fudged it enough so that the approximation works well for me, not unlike defining the tonal range of a negative in terms of the zone system. I do this strictly with the i1 and not by eye, although I do tweak it a bit later to bring it into compliance with the print scale and brightness. If your work is for display on a monitor, you may find this too limiting. It's a matter of taste, seems to me. But I have to say that watching a well made movie, b&w or color on this monitor calibrated and profiled correctly, is a joy! Even (especially?) films like "Casablanca"!
