How To Value Sketch / GunZet

INTRO:
So, you're wanting to get the hang of value and contrast? Then you've come to (almost) the right place. It's simple really, once you get the hang of it.
I myself neglected learning how to shade correctly for years in favor of increasing other skills instead. But I soon learned that value really adds depth to an object, and decided to pursue learning this on my own.
In short, after messing around a bit, I learned in near two days, just from experimentation (and being a fast learner).
And now I pass on what I've learned to willing others. Let's do this, F**K YEA!!

PART I - The Doodle

The doodle is the best way to start off, you need to have -something- visualized. Some people also do silhouettes to start them off, although all the detail isn't yet in place, so that makes it hard unless you have a clear vision of everything.
I personally start off with a little sketch/doodle, all details already drawn in and ready to be filled up with value.

I'll get to something cool later, but for right now, we start with the basics. And that means simple geometric shapes i.e. cubes, cones, spheres etc.
I've doodled an example of those three.

PART II - Blocking In And Choosing Light Direction/Source

This is the part where I usually choose where the light is coming from. Two of the easiest ones to do are from behind, or from the side, but it's best to practice with every direction you can.

First I block in with shades of gray, using a hard edged brush. The lighter the gray, the more light is hitting. When something is completely saturated with white, it'll look mostly just white. This takes practice and some fiddling around.

Do this on a separate layer, and on top of the sketch, the lines are only there to hold the shape of the object. Mess with the opacity so that you can see the lines through the gray, but can also still tell your darks from your lights.

And don't try to be so perfect in the stage, be as messy as you want, just keep a general idea in your head of where the light is hitting and you'll be fine.

PART III - Cleaning Up, Giving Prescence

Ok, so now you have a really ugly looking shape with really ugly looking shading, which is overall really ugly looking. Right.
So now it's time to make it a bit prettier.

Clean up the gray that falls outside the shape by erasing it. It doesn't have to be too good, just good enough.
Next, make a new layer. This is where edges, midtones, lightest lights, and darkest darks get semi-defined.
Take a medium sized soft brush (low flow and low opacity if you're using PhotoShop. I'm Using SketchBook Pro 2010) and go over the object lightly with either white or black. Depending on where your light is hitting, and where your shadows are.
Don't go overboard with it.

I also forgot something *facepalms*. At this point, or even BEFORE this step, I usually lay down a soft gray background to contrast more with the light. So if you haven't done this, do it on either the same layer, or a new one. If you do it on the same layer you'll probably get a better result, as you can still go over the edges and define them even more.
I also do a soft shadow and some secret ninja stuff you'll have to spot and try on your own.

PART IV - Detailing And Not Going Insane

And by this I'm mostly talking to myself...I'm a guy with a taste for detail, what can I say, I go crazy with the possibilites sometimes.
Anyway, for tutorials sake I'll throw a few scrapes and cuts into the shapes.
I used this to teach myself how to get used to other things on the same object interacting with the same light...it's complicated to explain, so I'll draw it instead.

As you can see, by drawing little cracks all over the place, this gives you a chance to experience with how the light interacts and practice more, instead of redrawing the same object over and over and OVER. Although some may prefer to do that, all the same.
I've also worked some strange forbidden magic to make the results of mine look a bit better...hint: draw, blend, go over, blend, go over, wash, rinse, repeat.
Basically what I just said is in order to make the cracks blend in with the object instead of sticking out, I went over the area with a gray of the surrounding shade, and went over some areas once again, to keep it both blended, yet sharp. Get it?

Of course you don't, this takes time.

I create a new layer, this will most likely be the final layer, but sometimes I add some extras.
Right now, I work with a very small brush, if you're not using a graphics tablet and don't have pressure sensitivity on, well...this will be tough. You can skip this though.

PART V - And From Here

You'll know when you're finished. As an artist I'm sure you'll keep going back and forth messing with stuff until it looks just right, and if you don't do that...maybe you should.
Also, with the full grayscale drawing done, you don't have to worry about too much when it comes to coloring. A nice combination of overlay, multiply or color layers should do the job. Experiment.

At this time, you can choose to either keep or delete your sketch layer. Why? Because amazingly, nearly no lines were used, WOOT! Because that increases the realism, although for style, I sometimes outline my stuff with a bright white outline.
It's whatever you want.

And here's that something cool I promised...cba, didn't finish, whatever.

Protip I learned from Cype and Rei: Go from dark to light, not light to dark. Unless you're that awesome.

Well that's odd, try using another browser? Maybe you have something set that blocks images *shrugs*

Also, no prob Lucifer, hope this helps peeps out a bit.

If you simply can't see the images,
1. You may be having very very slow internet.
2. Somebody may have disabled something on your browsers which is preventing you from seeing them.

If you see a frog in an ice-cube instead of the images, you have to be logged in imageshack.

These are the reasons I can think of based on my experience.

Great tutorial as always, GunZet! DHB - I'm surprised you can't see them - they work fine for me too and I'm using Firefox. Erm, if Gunzet doesn't mind, I can post the tutorial up in the Tutorials page and host all the images here in MT - maybe you will be able to see it then, doghateburger.

Thanks :D, I haven't made one in a long time...well posted one that is.
Also, I don't mind, post it wherever lol. The more people see it, the better.

Thank you for the turorial, GunZet.
I was unable to achieve the same result but maybe if I try a few more time ... :)

One thing you have to keep in mind when drawing like this. Is be messy, let your mind flow naturally. If you think about the technical stuff too much it just won't turn out right unless you're already a pro.

And yes, just keep on practicing, that's the biggest key to unlocking hidden potential. Everyone should practice, no matter how good you are. Thanks, and keep at it :]

Thanks man. That little hint you gave me on the GB that one day really did a lot.

Is there a reason why no reflected light was discussed?

GunZet

Yep. This was just meant to be very basic, but enough detail to give an idea of what to do. I assume most people who looks at this are already artists or want to get better...or maybe just starting. And knowing that, I also assume you experiment on your own. Basically saying "I figured this out on my own, why can't you?" lol.

But if anyone wants, I could add that also.

Lawl I'm just now seeing this haha. Awesome Rio, thanks.
Curious to see if this actually helped anyone.
