Re: Monitor - Eye Adaptation

Ron Kelly <ron@...>


You won't like my answer, probably. The answer is: if it's destined for print, proof it. That's the only way I know to get around your problem.

Even working by the numbers and using a calibrated monitor doesn't do it.

My experience is that my ability to "read" a screen is less reliable than I would like. There's the adaptation problem you've identified, and then there's
other things: you're not a robot, maybe you change one day to the next the way you see things because of fatigue, aging, nutrition, stress,
or even drugs such as alcohol and caffeine. That's not to mention that you're environment might change: the window light from the summer vs. other
seasons, equipment changes, etc.

My work schedule is also highly variable: my computer sits idle for long stretches while I'm away, and when I return it is a re-learning process.

I wonder how things go for people who sit in front of their screens every day, Do they find that they can see with "certainty?"

The gizmo pundits often imply that this is possible, but I never get there which leads me to the conclusion that I am insufficient, or they
are exaggerating, or some combination of both is at work.

Good luck,
Ron Kelly

I have a question about eye adaptation (not sure if that is the correct term). When editing an image in Photoshop, the longer I spend staring at the monitor, the more my eye adapts to what I am viewing, and the more normal it begins to appear. Sometimes, after 45 minutes working on an image, my wife will walk up and immediately say, "That's too green, contrasty, saturated, flat, or whatever." And, if I walk away from the computer for 5 minutes and come back, it becomes glaringly obvious to me too. The eye's ability to adapt to different lighting conditions is great for daily living, but it makes editing images difficult at times. I work visually and also use numbers (RGB, CMYK and Lab) as guides for white, neutrals, blacks, skin, sky, grass, etc, but still visual adaptation creeps in and messes me up. I know most people struggle with this issue to some extent. One thing I like about LightRoom is the ability to adjust images very quickly, so my visual system doesn't have as much time to "normalize" and play tricks on me. Unfortunately, LightRoom has many limitations, so most of my important images go to Photoshop. I know I can get up and walk away to 'recalibrate', but I prefer to stay put and just work on an image until it's done.

Does anyone have any suggestions, tips or solutions to help solve this human visual adaptation problem? Any links or articles that address it, and offer helpful suggestions? I'm curious wh
