I myself work as a designer as well, but I have never used a calibration system for the monitor... they aren't worth it. The clients, I mean the customers, are the abomination of the capitalist system and the fundamental core of its existence.
So yes, that's the point of model building, from my point of view. I guess that achieving accurate results is why I started building kits and investing a lot of money in tools and materials. Because if you like fantasy, that is OK, go with it, but I got bored with the dynamic of doing the same thing again and again. At some point, I just wanted to do more practical things. So when I saw videos on YouTube of fellow modelers and their builds, and how complex it is compared to miniature painting, I got into modeling without hesitation.
It's the combination of craftsmanship, art, and design that I love the most. You have to know a lot about planes, vehicles, history, events, and people. You have to have an eye for the details, but I'm still a noob and I admit sometimes it's very frustrating. But with help from fellow modelers, as you say, it's fun to learn and share the work.
Guess I'll have to resarch a lot and use my "powers" to nail the right color.
Thanx.
