I found no luck trying to do research on this, so I'll have to ask for advice. Bear with me. I have an Eizo ColorEdge CG223W. And, hands down, yes if I wanted to make a calibrated profile for doing my visual work, I'd absolutely use a hardware metering tool, not my subjective and opinionated perception! Eizo has preset modes. The mode called "custom", which is currently calibrated for my work use, is the only mode that the monitor allows the user to hand-adjust with the hardware buttons. The rest of the modes are common context presets (irrelevant for me), and then there's three empty slots for some more custom presets. Great, I thought, I'll just create an extra profile on one of those so I can switch between work mode and other modes by the push of a button. But apparently those additional custom profiles can only be created by using Color Navigator AND a hardware calibration tool, which I don't own. And even if I owned one, they're built for creating *faithful* profiles something that I already have and don't need. It's strange that Color Navigator just can't allow you to purposefully make a profile without hardware, even when you know what you're doing or aren't looking for scientific measuring. What's my point? Well, when I'm done with the day's visual work and the night falls, the flashing brightness is killing my eyes. I used f.lux (https://justgetflux.com/ which seemed really smart at first, but after a few weeks I found myself disabling it once its effect started to kick in in the evenings; Yes, the orange overlay makes it so much easier on the eyes if you're looking at a white page with black text, but for everything else, it's plain annoying. I usually study in the nighttime, I use a lot of colour indicators among text and graphics to comprehend things better, but as you can imagine, the orange overlay distorts the colours completely so you can't tell blue from green and so on. I'd need something more sophisticated. With a proper night mode profile I wouldn't have that horrible flashing screen stuck in my retinae long after I've left the workstation. Mac's built-in color calibration assistant only leads horribly astray (although it does an OK job if you're actually trying to calibrate some basic screen to look somewhat nice). But for this, its step by step wizard makes it impossible to keep track of an *entity* as it only lets you to adjust one parameter at a time parameters that it doesn't even literally explain to let you know what you're doing an adjustment for! It's just a vague "testing for the monitor's native luminance response". Doesn't mean much. When you blindly adjust those sliders one by one and think that it might be fine, the gamma adjustment step finally messes the previous settings up anyway and when you save the profile, it turns out as yet another surprise. I even tried adjusting the sliders randomly in numerous ways to just see if it would accidentally produce a bearable outcome, but that brought no luck either. Adjusting Eizo's hardware settings by buttons isn't an option because I require to switch between the modes every day. Also, creating a software-based profile would allow me to automate the profile to switch according to the time of day. Set it up, leave it and have a nice life. If there was a way to create and save a profile for easy switching. To adjust an entity instead of step-by-step-and-don't-go-back. To see what's changing while I'm still adjusting. To have the freedom to "adjust it all wrong" instead of faithfully. ...And this is only a hypothetical metaphor, but I wish I could do this by using something like the Photoshop curves tool. That kind of non-linear precision. Because the linear sliders (and the lack of them) have a major downside: When you get one tone right, move onto the next slider to adjust some other tone, the second slider will mess up the first tone again because nothing locks in place and the adjustment is not a "curve" but a meter. I'm not expecting to get the perfect solution that answers every problem but do you have any ideas that might be helpful for getting at least closer to the goal? Software, tools, hidden features, something I missed.
