ThereIsNoJustice's Sketchbook

Thanks for the words of encouragement, homies.

I went and fell into a pit for the last few months. The pit was writing the pathfinding for npcs in the game project I've mentioned in here. I have been very productive... just not with drawing or painting.

However, I did have an interesting talk with Muzz. He mentioned that all digital color spaces are gamma corrected. Which in plain english means that EDIT: colors tend to blend lighter, incorrectly. Paintings might be skewed toward lighter values, be more in midrange values. This means paintings have a tendency to lighten.

Before the edit I had here that the color picker wasn't presenting accurate info. That's actually wrong. I checked and the color picker in CSP is correctly presenting linear color space. But the blending in CSP will still be in srgb with a lightening tendency.

Anyway, something to look out for and experiment with. Tried to apply that w/ the paintings below.

Also, I need to figure out some scifi helmets and armor for the game... so more of that soon-ish.

Wow that last portrait looks beautiful!

When you say 50% is lighter in the corrected color space, if it looks correct on your screen, and it looks correct on my screen as well even though it's not really 50% grey, why do you need to correct for that? I could see an issue if you were going to print out your artwork. But I mean if it looks right it is right... right?

I feel like you just need to hit a bit more the dark and white spot just to create more interest and texture in the character. When you smash the value and leave a lot of the extremity of the value range out you get what i call ''sad value'' which you loose the richness the drama and the opportunity to create strong visual hierarchy. Smashing the value ( or taking working mostly with midtone) you create muted interest you make everything equally important to a degree.

By adding the hotspot(or highlight) you create some warmth and with a bit more dark inside the shadow you separate the figure from the background even more not that important here but sometime if you don't light properly loose the figure to the background when you don't create a ''1,2,3'' read as scott robertson would say. The hotspot also suggest the wetness/greasiness of the skin.

I also tried to see what this approach would do with the girl butt to see if it was a one time thing and i think you should consider what being said seriously in that one the form was getting lost in the background.

Re: the portrait, thanks!

And I had a conversation with someone else about the color space thing, and it's interesting to me that other artists have no issue with this. Or don't care, either way.

In the other conversation I had, the other person said something like, "Why does it matter? If something is too light, paint it darker, and if it's too dark, paint it lighter. Knowing this about digital color spaces changes nothing about how I would work."

Well, in theory that makes sense, but here are the issues I have with the color space.




EDIT: There used to be incorrect info here! Actually the UI is correctly displaying the linear color space in the color picker. Rather it is the blending which will tend to be happening in the srgb color space, and that will lighten colors in a way that is nonlinear and somewhat deceptive. The actual change in workflow should be to post process with adjustment layers, and mostly paint as normal. The idea of not neglecting darker colors is still valid, but that's not as related to this srgb color space stuff.

I'll quote Muzz who explains it this way: "8bit srgb has far less fidelity in dark ranges, making blending with dark colors glitchy and kinda broken. It sacrifices the darks in favor of having an expanded midrange."

I think you're right. The diffuse light value got too high in that portrait, and the highlights especially could've been stronger.

The butt painting I think is a better experiment with controlling the value range. It looks good to me, at least. Of course, all this stuff is a matter of preference to some degree...

I am not that aware of all the conversion theory from greyscale to color sadly so take it with a grain of salt and yes monitor and printing is an other level of expertise. My advise is try turning the drawing to color and see and find out for yourself when an when not to use different value range.

[JosephCow]

Oh yeah, I think I've heard that before in regards to blending of colors. It typically doesn't do it how you would expect traditionally. Not sure I really understand it, maybe I should look into that more. Though I think as long as you are aware of what you're doing and how it is looking it should be alright.

Love seeing updates from you, you have a great line quality in your works that I really enjoy. The Metroid sketch is fantastic, as are the recent value studies you completed. Keep up the great work!
