The key? Cloud
Brushes. Clouds Brushes are fairly easy
to make. Have your camera with you as
you travel around. When you see an
interesting clouds, take a few shots of them.
That's probably the easiest first step ever.
Make a folder for your cloud shots or do some Keywording to
be able to find your cloud images quickly after you do your import. Pick a cloud image, bring it into your image
editing program. Switch it to a Black
and White using whatever you like to use to make the conversion. I'll talk about using Adobe Photoshop Cs6
(since that what I use) but you can probably do the same things in whatever
you're using. This is one case where you
don't have to use Adjustment Layers since you'll be saving a Brush (B) and then
discarding the changes. Invert the cloud
image (CTRL I [eye]) and bring up the Levels (CTRL L) dialog box. Increase the contrast by bringing in the two
outer slider carets. The result doesn't
need to have a pure black or a pure white.
We're trying to make a semitransparent Brush.
Grab the Gradient Tool (G).
Choose a linear gradient and the foreground to transparent (in the dropdown) option (second from the
left). With your foreground color set to
white and drag in from the outside of the image. Drag the Gradient in all around the
image. You may have to drag as many as
ten or twelve times to get the entire outer rim to white.
Once the clouds appear in a ring of white you're ready to
make the Brush. The Brush will only be
whatever is black/grey (nothing white or light grey). Now create a Brush Preset. Click
on Edit/Define Brush Preset. A dialog
box will come up asking you to name the Brush.
Clouds are pretty standard so Clouds 1, Clouds 2, etc is probably as
good as anything. The new Brush Preset
will be appended to the brush set you have open. You may want to make folders and save all
your Clouds Brushes, your Fire Brushes, your Water Brushes in separate folders.
Once you have your Brushes defined you can choose a Cloud
Brush, set the foreground color to something that appears in your
"hero" image and start producing your background. I recommend using (and naming) each color and
cloud on a separate Layer.
If you were to make your foreground color Red and do one
click of the Brush and then change to foreground color to Blue (on another
Layer), you'd have some Red, some Blue and some purple. This would be due to the inherent
transparency of the Cloud Brushes .
