General Discussion / Re: Color balancing your pixel art
« on: February 26, 2015, 10:08:16 pm »
@Helm. Not so much a problem for the artist as the programmer. Brightness is exponential in nature, so when color-balancing you need to adjust for this to maintain the pereceptual brightness level. Then you have the boundary problem; 0-255...some requested adjustments simply can't be done to all colors without overshooting and corrupting the integrity. So you have to figure out how much change can actually be done to each color.

And if you wanna take this problem even further; there is this phenomena where colors approaching pure primaries appear "stronger" relative their brightness. I'm struggling to understand and quantify this effect, and I don't know if there's any colormodels that account for this (if someone has any info let me know). But in general I think the concept of brightness becomes muddled for more pure colors, esp. for red which is a "recent" evolutionary addition to the eye. Try comparing the brightness of pure red to doesn't quite compute.

@Dennis. Oh, young padawan...that's not even half of it.

Impressive, but I assume you haven't implemented functions/options for brightness-preservation which is key to quality color manipulation (however that can be a tricky sucker, one of the most challenging problems I've encountered...I landed on an iterative error-correction)

@Helm: Grafx2 allows you to, in realtime, change any color-channel for one color or a range of colors. The buttons on the right also allows to change the brightness of the selection (+/- 1 to all three channels). There's also HSV controls. (However there's no automatic brightness preservation etc.) You can quite easily re-arrange the palette if you need to group the colors to be affected. Nothing really advanced, but it works very smoothly.

As for the scripts, they can do pretty much everything...but they don't have interactive controls, thus not updating in real time :(  So it can require a bit of trial & error. Although it IS possible to write interactive/updating scripts controlled via keyboard.

@Helm: Ah, ok. Hmmm...are you implying this is an uncommon practice? If an artist is working with +20 color palette and feels it needs a bit more red...I hope his program allows for some method to tweak all or a selection of colors at once.

On a more technical note; I'm glad you brought up color balancing rather than hue-shifting which usually offers less control and can be a bit destructive.

At least Grafx2 provides very good palette control, and while I have lua-scripts that can perform every thinkable color-modification, I still find that manual RGB-slider tweaking suffice 95% of the time.

I don't think there's anything wrong with a bit of color-balancing, hue-shifting or any other color-tweaking, if it will help the artist fulfill his vision. Esp. if one is working on larger scenery with a certain mood/atmosphere (like your recent image) it's quite applicable to make (some) broad-spectrum adjustments rather than constantly tweaking individual color indexes.

You're touching on several issues here...not quite sure what the focus is.

I'm leading you where you need to go. You now realize none of you have any legal claims on concepts or specific information. It's just down to presentation or specific imagery, correct? Was your material ripped or just mimicked to some degree? Does it exceed potential quotation rights? Are your images so original that convey more than common knowledge and information in the public domain?

Credits are nice, and not referencing your sources is bad form. It's annoying but not illegal.

Let's keep information free, advance science and rejoice in the proliferation of pixelart-knowledge.

But yeah, credits where credits' due.

Ok, let every person who claims to own the copyright and/or intellectual property to a specific piece of information/knowledge step forward; with real name and contact information, and specify the contested information and provide indisputable proof that he or she is the ORIGINAL author and sole lawful proprietor of said information.

If you can't do that... you might wanna keep the legal threats at a minimum!

(I'm dying to see who among you will claim ownership of different pixelart techniques...)

Someone took the time and effort to write a book/summary on a topic you hold dear, and the problem is?... seriously, think about it, specifiy it and spell it out. I'll bet you're gonna feel pretty foolish once you break it down.

Yes, and JPEG is a lossy format that will corrupt your image. Only use PNG and GIF.
