SymmetryShop lets you create and edit
repeat patterns without leaving the
SymmetryShop palette. Alternatively, you
can work in Photoshop and run the plug-in
as an action to rebuild the pattern as you
edit the seed image, the selection, or the
control path. In this tutorial you will learn to
edit the control path with Photoshop tools
and run the plug-in as an action to
interactively modify the pattern. You may
want to have a look at another Artlandia
SymmetryShop tutorial "Creating Drop Repeats" first for general tips on getting
started with SymmetryShop.
- Open the file Lilies.psd, which
accompanies this tutorial, or use your own motif.
- Select your seed image using any of the
selection tool in Photoshop and launch
SymmetryShop by choosing File >
Automate > Artlandia SymmetryShop....
- In the SymmetryShop palette, click the
Glide reflection button, set the tiling size
to 2 × 3, and click OK to return to
Photoshop.
- Choose Select > Deselect or press Ctrl-D
(Windows) or Command-D (Mac OS).
You do not need to worry about the
selection any longer because
SymmetryShop recorded it in the
SymmetryShop Selection channel and
will use it when you want to rebuild the
pattern. (You can see the channel in the
Channels panel.)
- For the Glide reflection symmetry
setting, every other row of your pattern
is a reflection of an adjacent row. You
will now adjust the control path so that
reflected images get closer to the original
ones to form vines. You will also bring
vines closer to each other. Feel free to
peek at the pattern in the end of the
tutorial. The intermediary steps will then
make more sense.
When SymmetryShop created the pattern,
it saved the control path as a work path in
your document. The path is called the
"control path" because SymmetryShop
uses the path size and orientation to build
your pattern. You can edit the path using
the usual Photoshop tools. To begin, open
the Paths palette (Window > Paths) if it is
not open and click the Work path.
- Choose the Direct-Selection tool in the
Photoshop toolbox, click the upper side
of the work path and drag it down a
little past the smaller lily. You can press
the Shift key as you drag to keep the
rectangular shape of the path (or not
worry about that because
SymmetryShop will rebuild the control
path should your edits destroy its
rectangular shape).
- You are now ready to rebuild the pattern
to take into account your smaller control
path. Instead of going through the File >
Automate menu after each edit, you will
create a Photoshop action that runs the
plug-in automatically. The following
steps assume that you have not yet
recorded an action to run
SymmetryShop. If you have, skip
directly to Step 12.
Start by opening the Actions palette if it is
not open (Window > Actions).
- In the Actions palette, click the Create
new set button (or select another subset
where you want to put your new action).
Then click the Create new action button.
- In the New Action dialog, fill in the
name of your new action (for example, "SymmetryShop"), choose a function
key (for example, F12), and select the
Ctrl checkbox (Windows) or the
Command checkbox (Mac OS). You can
choose any other name or key
combination you like and click Record.
- The action you create will be very
simple. Launch the plug-in by choosing
File > Automate > Artlandia
SymmetryShop... and click OK. This
rebuilds your pattern and returns you to
Photoshop.
- Click the Stop playing/recording button
in the Actions palette. Your action is
ready. From now on, you can launch the
plug-in by playing the action using the
keyboard shortcut, which may be more
convenient than going through the
menu.
- It is often even more convenient to
toggle the action's dialog off. This will
let SymmetryShop rebuild your pattern
without asking any questions, which is
what you want for interactive work on
your pattern. Toggle the dialog off now
by clicking the dialog icon.
- Back in your pattern, notice that the
distance between pattern rows
decreased following the reduction in the
height of the control path. However, you
still need to move the reflected rows to
the left so that stems intervene and make
vines.
- With the Direct-Selection tool, click the
left side of the control path and drag it to
the left to make the control path about
25% wider.
- Alt-click the control path (Windows) or
Option-click (Mac OS) to select the entire
control path and drag the control path as
a whole to the left. Rebuild the pattern
by pressing the shortcut you chose for
the SymmetryShop action.
- Your pattern is almost ready, but you
can fine-tune the control path still more
to align stems better. The final pattern
may look like the one at the bottom of
this page.
You can make the pattern a little more
interesting by creating a repeat pattern in the
background. For step-by-step instructions,
see another Artlandia SymmetryShop
tutorial, "Repeating Backgrounds for Repeat Patterns".
