In this tutorial, I will show you the steps I took to create a realistic nebula scene from scratch in Photoshop. We will be using technques such as the Pen Tool, various filters for texture rendering, layer blending and some dynamic brushes.

I would also like to take this opportunity to wish everyone a very happy new year and all the best for 2009! Thanks very much for visiting my blog and hope to see you again next year!

Here is a preview of the final result:

OK let’s get started!

Step 1

Create a new document sized 1200×800, fill the background layer with black colour. Make a new layer on top of the background layer and name it “Nebula Outline”.

Hit the “P” key to select the Pen Tool and make sure the “Paths” option is selected. I won’t go into explaining how to use the Pen Tool in this tutorial, but if you haven’t used it before, I have a post here with some links of the basics of Pen Tool.

Draw a random, irregular shape as shonw below on the “Nebula Outline” layer:

Step 2

Still on the “Nebula Outline” layer and the Pen Tool selected, right click on the path and choose “Make Selection”:

Apply the following settings: (I used 25 pixel feather radius because I would like the selection to be as smooth as possible)

Your path will now become a selection with 25 pixel feather radius:

Step 3

Go to Filter > Render > Cloud and render some cloud, with White foreground colour and Black background colour.

Hit Ctrl + L to bring up the level tool, apply the following settings:

Using the level tool we can adjust the input level of different colour channels. Your image will now look like this:

Step 4

Now we can some depth the Nebula. To do this, create a new layer called “nebula overlay”, use the Clone Stamp Tool with the following settings:

Hold down the Alt key + Left Click to define a Clone Source, cloud some cloud from the previous layer.

Because we used a reletively lower opacity and flow, you will see the difference between each cloud:

Merge the two layer together and name the merged layer “Nebula”.

Step 5

Nebula doesn’t only consist of cloud, there are also some small particles and dusts inside. Now we’re going add them in.

Duplicate the “nebula overlay” layer once and name this layer “particles”. Go to Filter > Sketch > Photocopy and apply the following settings:

Then go to Filter > Sketch > Chrome and apply the following settings:

Change the layer blending mode to “Color Dodge” and set the opacity to 80%.

The result so far will look like this:

Optional: you can duplicate this particles layer a couple of time if you feel like add more paricles onto the cloud.

Step 6

Now we can add a bit motion into the image. Duplicate the “Nebula” layer once and put the duplicated layer above the “Nebula” layer. Go to Filter > Blur > Radial Blur and apply the following settings:

Then go to Filter > Distort > Ocean Ripple and apply the following settings:

Change the layer blending mode of this layer to “Overlay” with an opacity of 30%. You image will now look like this:

Step 7

Create a new layer called “Star”, grab a 9px round circle brush, and apply the following brush dynamics:

Shape Dynamics

Scattering

Noise

Paint over the “Star” layer as the image shown below:

Optional: To add some light glow and softness, you can duplicate the “star” layer once, and go to Filter > Blur > Gaussian blur and apply the following settings:

Step 8

Create a layer called “Colour Overlay” and set the blending mode to “Color”, then simply grab a big round brush (300px) and choose some nice, space-feeling colour and paint!

You can also adjust the opacity and the flow of the brush for some colour depth. Hint: after painting colour, try duplicate this layer a couple of times and see what result that brings you.

Here is my result so far:

Ok that’s it for this tutorial! The rest is left upon your own creativity.

Here is my final image for this tutorial: (I simply erase some portions of the nebula cloud and add a shining planet to it!)

Hope you enjoy this tutorial and if you have any questions, just drop me a comment.

Thanks very much and have a wonderful and colourful new year!
