+
+## Intention
+
+So, we want to create a nice paintbrush image with GIMP. This tutorial can be a bit complex and I think it
is better for a bit more advanced GIMPer. If you want to learn the basics, a good way to do so is to get one
of the many GIMP books written. If I must pick one to recommend, I think it would be [Grokking The
Gimp](http://gimp-savvy.com/BOOK/index.html), it is pretty good. But I am sure many of the others are great
too, check a few out at your bookstore!
+
+## Step 1
+
+<figure>
+<img src="1.png" alt="1.png"/>
+</figure>
+
+Anyway, we start off with a plain gray image.
+
+## Step 2
+
+<figure>
+<img src="2.png" alt="2.png"/>
+</figure>
+
+We first create a new transparent layer, and name it "tip" since we start drawing the brush from the brush
tip.
+
+## Step 3
+
+<figure>
+<img src="3.png" alt="3.png"/>
+</figure>
+
+Use the Bezier (Paths) tool to make a brush-shaped selection, like on the above image. This could be tricky
if you are not used to the tool, so it might be helpful to check out my Bezier tool tutorials if you have
trouble.
+
+## Step 4
+
+<figure>
+<img src="4.png" alt="4.png"/>
+</figure>
+
+Just fill the selection with black color.
+
+## Step 5
+
+<figure>
+<img src="5.png" alt="5.png"/>
+</figure>
+
+Make another bezier selection, now inside the black brush tip. Since a wet brush tip is rather shiny, we
want to add a hilight too make it look realistic. Try to think where the light comes from, and make the
selection accordingly.
+
+## Step 6
+
+<figure>
+<img src="6.png" alt="6.png"/>
+</figure>
+
+We are going to use the Blend tool (gradient fill) to make the hilight. You might want to make a new layer
for the hilight so you can edit it later if you are not happy with the result.
+
+The important thing here is to set the blend mode to "FG to Transparent", we only want to add white, not the
black.
+
+## Step 7
+
+<figure>
+<img src="7.png" alt="7.png"/>
+</figure>
+
+Make a blend from top to bottom, so that the white fades out towards the brush tip.
+
+## Step 8
+
+<figure>
+<img src="8.png" alt="8.png"/>
+</figure>
+
+Then make another bezier selection that will form the brush metal handle, this is a bit more tricky, try to
think where the brush handle will point, and add small "roundings" to the ends. Then fill the selection with
a rather mid gray gradient. It does not look very real yet, but we want to bring this to life next...
+
+## Step 9
+
+<figure>
+<img src="9.png" alt="9.png"/>
+</figure>
+
+Keep the selection active still, and start adding black shadows with the airbrush tool so the shape gets
some depth and looks more three-dimensional.
+
+This takes a bit of work, start first with large fuzzy brush, and work towards finer detail by using a
smaller fuzzy brush. As far as I know, real airbrush artists use the same method to paint, they just use
masking film and tape in place of the bezier selection.
+
+Again, think how the light would reflect and how the shadows would be on a real object. And dont worry if it
does not look right at first, it needs some practice and patience.
+
+## Step 10
+
+<figure>
+<img src="10.png" alt="10.png"/>
+</figure>
+
+Also add some hilights by using white color on the airbrush. You can make the object appear more metal-like
by adding a second hilight to the "shadow" edge as if it was reflected from the background plane. If your
background was having some color, you could add slight tint of that color to the "second" reflection.
+
+Again, since the metal has a pretty shiny surface, you can use the Dodge/Burn tool to make the shadows and
hilights stronger. Using brighness and contrast might help too.
+
+## Step 11
+
+<figure>
+<img src="11.png" alt="11.png"/>
+</figure>
+
+We add the "engraving" by painting black with a very small brush, airbrush again works well. Try to make it
look like some letter ornament or whatever you like.
+
+## Step 12
+
+<figure>
+<img src="12.png" alt="12.png"/>
+</figure>
+
+Add hilights with white color to the areas that would get reflection. Since the light comes from top left,
the hilights go to bottom right of the black "engraved" shapes.
+
+## Step 13
+
+<figure>
+<img src="13.png" alt="13.png"/>
+</figure>
+
+Next we want to do the rest of the handle. We again create a new layer for it. Since it comes from "inside"
the metal part, it is better to put it behind the metal part layers.
+
+## Step 14
+
+<figure>
+<img src="14.png" alt="14.png"/>
+</figure>
+
+Again, the bezier selection tool. Yes, I love it. You should too. Make a nice tapered shape that represents
the brush handle.
+
+## Step 15
+
+<figure>
+<img src="15.png" alt="15.png"/>
+</figure>
+
+Doubleclick the "Bucket fill" tool and select "Pattern source" from the tool options window. Select one of
the wooden patterns. This will make the texture of the handle. Fill the selection with the wooden pattern.
+
+## Step 16
+
+<figure>
+<img src="16.png" alt="16.png"/>
+</figure>
+
+Add another layer, this time for the hilight of the wood. Position it just above the handle layer.
+
+## Step 17
+
+<figure>
+<img src="17.png" alt="17.png"/>
+</figure>
+
+First, like you did on the "metal" part, shade the wooden handle a bit with the airbrush tool so it looks
round. Then do a hilight like you did for the brush tip on steps 5-7\. You might want to reduce the fill
opacity a bit since the wood is quite not as shiny as the wet brush tip.
+
+## Step 18
+
+<figure>
+<img src="18.png" alt="18.png"/>
+</figure>
+
+Okay, it looks very much like a brush already... Lets just add a shadow and it looks better.
+
+## Step 19
+
+<figure>
+<img src="19.png" alt="19.png"/>
+</figure>
+
+Duplicate the image, delete the background and select "Merge visible layers" to make the brush just one
layer. We are going to make this copy into a drop shadow for the original brush.
+
+## Step 20
+
+<figure>
+<img src="20.png" alt="20.png"/>
+</figure>
+
+Turn on "Keep Trans" checkbox on the layers dialog, and select the whole image and fill it black with the
bucket fill tool.
+
+## Step 21
+
+<figure>
+<img src="21.png" alt="21.png"/>
+</figure>
+
+Unselect the "keep trans" and blur the layer a fair bit, I think I used something like 20 for the radius.
+
+## Step 22
+
+<figure>
+<img src="22.png" alt="22.png"/>
+</figure>
+
+Now scale the shadow image so that it is 60% of the original height, but keep the original width. You need
to click the "chain" button on the scale dialog to change the image's aspect ratio.
+
+## Step 23
+
+<figure>
+<img src="23.png" alt="23.png"/>
+</figure>
+
+Copy the shadow image on the original brush image, and move it just above the background layer. The easiest
way to copy a layer is to drag it from the layers dialog to an image.
+
+## Step 24
+
+<figure>
+<img src="24.png" alt="24.png"/>
+</figure>
+
+I wanted to erase some of the shadow of the handle so it looks more realistic. I just used the eraser tool
with a big fuzzy brush.
+
+## Step 25
+
+<figure>
+<img src="25.png" alt="25.png"/>
+</figure>
+
+There! The finished paintbrush image. And you learned a lot about GIMP as well.
+
+Thank you for the interest :-) You can get the image I did for this tutorial in GIMP XCF format

+## Intention
+
+The Path Tool (replacing the old Bezier Selection tool) can be used in many creative ways. Maybe the best
thing in it is the smooth, beautiful curves it produces. But you can also use paths to create different
polygonal shapes if you don't 'pull out the handles'. Polygonal shapes are especially useful when painting
some geometric objects, as you can draw one side at a time (into different layers if you want).
+
+## Shapes with Paths!?
+

+
+This tutorial is about making simple geometrical shapes with GIMP. I will concentrate on the Path tool since
I find it so useful for this purpose. I hope you get some help and new stuff to put in your GIMP Tricks Sack
:) I personally use this technique for nearly all my work.
+
+**Notice!** This is not a 'back to basics' -tutorial. You should be familiar with GIMP's dialogs and menus.
I was thinking about this, and I did not want to make this an 'entry level' thing, basically to avoid
bloating this too big and duplicating other people's work. [Paths are covered in my other
tutorial](/tutorials/Bezier_Selections/), and I recommend you to read it before going further if you find the
material here confusing. If you are new to GIMP I suggest you to go to the GIMP homepage in
[www.gimp.org](http://www.gimp.org/) and first read through the Documentation section there.
+
+## Let's get started!
+
+First we must **create a new image** for our creation. Make the **size 256x256** pixels and choose **RGB**
for the type. The image background should be white. During this tutorial, you will have to use the Layers tab
and optionally the Paths tab from the dock "Layers, Channels, Paths, Undo". This dock is present in the
default GIMP installation. You can also get these tabs using <span class="filter"><Image> Dialogs ->
Layers</span> and <span class="filter"><Image> Dialogs -> Paths</span>.
+
+## 1. Left side
+
+<figure>
+<img src="box_numb.png" alt="box_numb.png"/>
+</figure>
+
+Now create a new transparent layer, and name it *Left_side* so you know what layer I'll talk about later on.
Make sure you have the new layer active by checking the layers-dialog. If it is not selected, click the
layer's name in the dialog.
+
+Imagine the blue cube on the right side into your canvas, we'll be doing side #1 now.
+
+<figure>
+<img src="left_side.png" alt="left_side.png"/>
+</figure>
+
+
+<img src="bezier_button.png" alt="bezier_button.png"/> Choose the Path tool and make something like the side
#1 on the blue cube, think about the perspective. (If this causes you trouble, don't worry. You will learn by
experience).
+
+You can adjust the points' places if you can't get them right at the first try, see the [Path
tutorial](/tutorials/Bezier_Selections/) for more information on that. Your path should look something like
the one on the right.
+
+Once you are satisfied with your "box", convert it to a selection using the button "Create Selection from
Path" (in the Path Options dialog) or using "Selection to Path" (in the Paths tab).
+
+<figure>
+<img src="gradient1.png" alt="gradient1.png"/>
+</figure>
+
+Next we must choose some nice colors for our gradient, choose white for the foreground color and some
dark-blue for the background (we are making a blue box, remember?) Something like that on the image nearby.
+
+<figure>
+<img src="colors.png" alt="colors.png"/>
+</figure>
+
+<img src="gradient_button.png" alt="gradient_button.png"/> Select the gradient-fill tool and, starting from
the top-left of the selection, 'drag' the gradient quite far down-right (see the arrow in the image. This way
you get a quite light-colored face for the cube, and it is just what we want here. We also want the lighter
end of the gradient to be near our imaginative light source. (The light was coming from the left)
+
+## 2. Right side
+
+<figure>
+<img src="gradient2.png" alt="gradient2.png"/>
+</figure>
+
+Now on to the right side, side #2. Create a new transparent layer and name it *Right_side*. Use the Path
Tool and try to make the right side of the cube and turn it into a selection.
+
+Take the Gradient Tool again and, still with the same colors, make a gradient from farther up-left to near
the selection's lower-right corner (see image on right). This way we get a darker gradient suitable for the
shadow-side.
+
+**Hint!** Be careful with the edges. You don't want to leave any holes so the background can be seen
through... It's better to overlap the lower layer a bit than leave a space between them.
+
+## 3. Top side
+
+<figure>
+<img src="gradient3.png" alt="gradient3.png"/>
+</figure>
+
+Our final ultimate task is to create the top, side #3. Again, create a new transparent layer and name it
(who quessed? :) *Top_side*.
+
+Now you probably know we want to make yet another path and this time the gradient has to be even lighter
than in the first side. So I suggest you lighten the dark blue color a fair amount, it's easier to get a
light gradient that way. This time you pull the gradient from left to right, according the arrow in the
picture. Once you find the shading look good, you can flatten the image and our little tutorial-cube is
finished. Now apply for your 'Cube GIMP Licence' from the nearest GIMP Station ;)
+
+## 4. Finished Work
+
+<figure>
+<img src="finished_image.png" alt="finished_image.png"/>
+</figure>
+
+Now you have a cool image of a Light-Source-Shaded Cube. You can choose <span class="filter"><Image> Image
-> Flatten Image</span> to merge the layers togerher so you can save as jpeg or any other format than xcf.
Or, better still, from the layers dialog, make the background invisible and choose <span
class="filter"><Image> Image -> Merge Visible Layers</span> so you will have the background on a separate
layer and you can work further on it if you like.
+
+The next thing is to start using the geometrical shapes as building blocks to make things. And you can twist
the beziers to make a bit more fancy stuff...
+
+I have provided [the xcf-file](example.xcf.gz) for the image we just created, if you want to experiment with
it, although you should be perfectly able to do just as good yourself.
+Thanks for your interest.
