One thing I wish I could adapt from traditional media is the control of the color. Yes, you don't have all these fancy hue/saturation/contrast sliders, but once you put the color on it, you know how it looks like. In digital not necessarily.
I'm bringing my deviantArt profile back from the dead and while browsing some older works to upload I'm constantly like "whaaa? This is not final right? Must be w.i.p? Someone tell me it's not final art I actually sent to publisher?"
So this is what happened, obviously I knew colors would be important in my job so I invested in quite a good monitor, but when it came to callibration I thought meh, how off can it be? I prolly won't even notice. I'll just load pre-configured icc profile and use system callibration. And you know what? Now when I actually used callibrator, the difference is HUGE. Like, not only from a colorist's standpoint, literally everyone would notice a big change in display. Earlier everything was on warmer, yellowish and more saturated side and the monitor was pretty bright. Which seemed totally fine and natural to me. Now it's darker and cooler in tones and it's actually much easier to work on. I didn't realize how the previous settings made me skip so many details and tones. And while some old works don't look much different now, the others make me wanna cry. All depending on what color scheme I used.
I'm writing this long post simply as a piece of advice for new digital artists working with color. You may be lucky and your monitor may display correct colors straight out of the box, but that rarely happens and do you really wanna risk it? Yes, majority of people who watch your work won't have their displays callibrated either, but from my experience, when source file is well done, it looks different but still good on every display. And when it's messed up, it's a lottery and there will most likely something be always slightly wrong with it. And if you're going to print your work, it's even more important. Callibrator is as important as good monitor.
That being said, I'm going back to crying over my destroyed covers now
