Hi. This is Marty from Blue Lightning TV. I'm going to show you how to create
an asteroid from scratch.
Open a new document by pressing Ctrl + N
on Windows or Cmd + N on a Mac. Make its size 1280 by 720 pixels
with a Resolution of 150 pixels per inch.
We'll fill it with black.
If your foreground and background colors
aren't black and white respectively, press "D"
on your keyboard. Since Black is your foreground color,
press Alt + Delete on Windows or Opt + Delete on a Mac.
To fit it onto your screen, press Ctrl
or Cmd + 0. Open your Pencil Tool
and make its Size: 3 pixels
and the Hardness: 100%. Draw the shape of the asteroid.
It could be any shape you want, as long as the edges
are a bit craggy. Open your Paint Bucket Tool
and click inside the shape to fill it. Press "Q"
to make it into a selection and then invert the selection
by pressing Ctrl or Cmd + Shift + I.
Press Ctrl or Cmd + J
to cut and copy the shape from the background. Ctrl-click
or Cmd-click on the thumbnail to bring back the selection of its shape.
Go to Filter, Render
and Clouds. Go back to Filter,
Render and Difference Clouds. Delete the selection
by pressing Ctrl or Cmd + D. Next,
we'll add soft brush marks, which will ultimately simulate craters.
Open your Brush Tool, open the Gear icon
and choose "M Brushes".
This comes with Photoshop. Click OK to see just the "M Brushes"
in the thumbnail window. Click back on the Gear icon
and choose "Large List". Scroll down
and choose "Fuzzy". Click on various parts of the shape.
We'll add black brush marks as well,
by inverting your foreground and background colors
by pressing "x" on your keyboard.
Go to Filter and Filter Gallery. Open the Sketch folder
and click on "Bas Relief". The Detail
is 15... the Smoothness is 2...
and the Light is from the Left.
Then, click OK. Next, we're going to make the asteroid look more dimensional. Click
on the New Layer
icon to make a new layer. Ctrl-click
or Cmd-click on the thumbnail of the asteroid to make a selection
of its shape. Press "Q" to make it into a quickmask.
Open your Pencil Tool, go to the bottom-middle
and draw an irregular, jagged line ending at the upper-right edge.
Open your Paint Bucket Tool and click to the left of the jagged line you just
made.
Make it into a selection and go to Select,
Modify and Feather. Feather it 1 pixel,
Fill the selection
with black and delete the selection.
Don't be concerned with the fringe around the outer edge.
We'll take care of that later. Change the Blend Mode to Overlay
and reduce its Opacity to 65%.
Make a copy of it.
We'll merge the 3 layers by Shift-clicking
on the asteroid to highlight all the layers
and pressing Ctrl or Cmd + E.
Double-click on the asteroid to open its Layer Style window
Click "Bevel and Emboss" and "Contour".
The Style is Inner Bevel... the Technique
is Smooth... the Direction is Up
and slide the Size all the way to the right.
Make the Highlight Mode: Soft
Light and the Opacity...
100%. Make the Shadow Mode...
Overlay and reduce its Opacity...
50%. Then, click OK or press
Enter or Return.
Go to Layer, Rasterize and Layer Style.
This fuses the Layer Style effects into the layer, itself.
We'll name it "Asteroid".
Go to Filter, Sharpen and Sharpen More.
If you want to angle it, open in your Transform Tool
by pressing Ctrl or Cmd + T.
Go to a corner and when you see a curved, double-arrow,
rotate it to an angle you like.
To reposition it, click inside the Transform
and move it. Then, press the Enter or Return.
Next, we'll rough up the darker, outer edges.
Click on the Layer Mask icon to make a layer mask
next to the asteroid. Open your Brush Tool
and reduce the Size to 20 pixels. Keep the Hardness...
0%. Brush over the outer edges
on the right and bottom.
Next, we'll create a dust cloud trailing behind the asteroid.
Make a new layer and make the opacity
of your brush: 20%. Make your Brush Size
300 pixels. Now, brush behind the asteroid.
Make all the strokes the same angle. Reduce the size of the brush
to 175 pixels and make more brush strokes.
Reduce the brush size again to 70 pixels
and stroke across the bottom edge and the top edge.
Next, we'll create a star field.
Make your background active and go to Filter,
Noise and "Add Noise". Make the amount 15%,
Gaussian and Monochromatic. Then, click OK.
Go back to Filter, Blur and Gaussian Blur.
Make the Radius: point 3 pixels. Then,
click OK or press Enter or Return.
Press Ctrl or Cmd + L to open your Levels window.
Slide the Input white level to the left
and the Input black level to the right until you're happy with the brightness
and quantity of stars.
For this example, I made the Input black: 38
and the Input white: 80. Next,
we'll add a thick cloud of dust just behind the asteroid.
Make the top layer active and make a new layer
above it. Make your brush size: 125 pixels
and reduce its Opacity 50%. Now,
brush in short strokes. We'll blend them in next.
Make a Layer Mask next to the layer.
Enlarge the brush size to 400 pixels
and brush over the outer areas of the short strokes to gradually hide them
leaving the areas close to the asteroid mostly
untouched. You can also enlarge or reduce the size of your brush
by pressing the right or left bracket key. Make your brush
smaller and brush on the asteroid
to reveal those areas that were cloaked by the dust cloud.
Next, we'll add smaller asteroids trailing behind the main one.
Click on the asteroid to make it active and make a copy of it.
Open your Transform Tool and go to the lower,
right corner. When you see a diagonal, double-arrow,
press and hold "Shift" and drag in to reduce the asteroid size.
Position it and rotate it to an angle you like.
Then, press Enter or Return. Make a copy of the small asteroid
and open your Transform Tool. Drag it to another position
and rotate it to another angle. If you want to manipulate
its shape, go to a corner and press and hold
Ctrl or Cmd as you drag the corner.
Repeat this with other corners until you're happy with the overall shape.
Then, press Enter or Return.
Make a copy of it, open your Transform Tool,
and drag the copy to another location. Reduce its size,
rotate it and drag it to another position.
Next, we'll add dust clouds trailing behind the small
asteroids. Make a new layer
and reduce the size of your brush.
Reduce the opacity to 10%.
Now, brush in dust clouds behind them.
This is Marty from Blue Lightning TV. Thanks for watching!
