| p.1 #1 · Calibrated Monitor vs. Eye / Brain Accommodation ... ??? |
Many of us understand that when it comes to WB we can't trust our eyes because of the way our eye/brain will accommodate or adjust to its environment and/or what we are looking at.
But, how long does it typically take for us to re-adjust to a change? For instance, good ol' Windows installs some updates overnight and I start up this morning and as everything reloads, my monitor calibration program kicks in and I see the changes go from what appears to be white & bright to what now looks like blue and dim.
My initial gut response is "something's gone wrong, it looked white before (word document, etc.), now it looks blue" ... but I know that nothing is wrong as this has happened many times before and I go on about my business for 20 minutes or so looking at a variety of things. Then, when I go back to look at those things that previously "looked blue and dim" to me (which also were perceived as white & bright pre-calibration), they are now again perceived as a very satisfying bright white.
Nothing has changed, and I'm not inquiring about any kind of a problem, because there isn't a problem in play here. This is similar to whenever I do a recalibration and then compare the before/after, the after always seems "too blue and dim". Of course, this is the amount of correction that is being applied to render neutrality, etc. ... my question is does anyone have any insight into how long it takes for our eye/brain accommodation to "make the switch" so to speak? We hear about allowing time for our monitors to warm up before calibrating, but is there also a "lag time" that we need to allow for ourselves to adjust to the changes before doing any "by eye" adjustments.
I'm not overly worried about it, because I first do my WB "by the numbers" rather than by my eye, then apply any "by eye" aesthetic afterwards. I also work fairly slowly, so I'm pretty sure that I get accommodated ... but still, I am curiously wondering how long it takes for us to accommodate to such changes when we recalibrate or maybe when we re-enter our workstation environment after being in other lighting environments, or when we change environments with our mobile viewing/editing.
