    galaxy is a massive collection of stars, stellar remains, gas, dust, and planets. Galaxies can contain as few as 10 million stars, or as many as 100 trillion. Astronomers believe that there are ablion galaxies in our universe, each varying in shape from spiral, elliptical, to irregular. In todays tutorial, we will demonstrate how to create a spiral galaxy of your own and will depict a flee

    aking its way through the universe to find a new home.

    days tutorial is part of a 4-part series depicting the journey of the inhabitance of a dying world that must travel into the unknown to find a new world to call home. In this series, we will expsmos from the perspective of this fictional civilization making their way through the universe and will demonstrate the techniques that you can use in Photoshop to depict your own cosmic scdition to written content, this tutorial also includes about 90 minutes of video instruction to help you along the way. So what are you waiting for? Lets get started!

    Step 1 The Galaxye will begin with the main feature of this image and the most important. This is a very long step because of all the settings and clicks you have to go through, but its not complicated its just a lowing it and you will see soon enough how we will progress through it and how each steps provides us with valuable content. Lets begin by creating a document where we will be generatinse for the galaxy not the main image document; so go ahead and create a new document with the settings as shown here.

    2/63

    ow select black and fill in your canvas.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    3/63

    K next create a new layer on top and go to the clouds filter and generate some.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    4/63

    en you will go to difference clouds and generate some on the same layer twice.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    5/63

    is is what you should get after these steps.

    K now lets create another layer and fill it up with black.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    6/63

    is time we will be using the fibers filter with the settings shown below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    7/63

    ow just setup this new layer to overlay so it mixes nicely with the clouds we did before.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    8/63

    ext we will reduce the opacity of the cloud layer as shown to make the two blend even further, and then just flatten all the layers.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    9/63

    ow we will create a new layer, drag it to the bottom and fill it up with black.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    10/63

    K perfect, now we will have to define a big circular selection with a feather of about 50px over our texture.

    en you can either copy and paste it to a new layer or inverse it and delete what its outside to end up with a big soft circle of the texture we created.

    K next up to give some twist and form to this we will apply the warp filter a couple of times with the twist option as shown below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    11/63

    soon as you select the twist option you will get its options in the top bar so lets type 100 for the bend setting.

    is is what you will see in your Photoshop screen, so hit apply and repeat the process once more.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    12/63

    nce both warp distortions have been applied lets use yet another filter; this time the twirl and use the settings shown below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    13/63

    K great now lets duplicate the layer so we can add some more detail.

    nd in this new layer lets apply a spatter filter with the settings shown here.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    14/63

    ere is what you will get from this last filter.

    ow set this new effect to screen and reduce the opacity a bit to about 61%

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    15/63

    ery good now make a duplicate of this last layer and apply some levels to it as shown below, so we get nice intensified highlights.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    16/63

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    17/63

    rfect we are done with this filter bonanza, now select all the layers excluding the black background and merge them together.

    K now we are ready to create the document for the image we will be working on, so select new file and create it with the settings below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    18/63

    ow fill the canvas with black.

    ext we will copy and paste our galaxy work on to this new document and in a new layer, then we will use the distort command so it fits inside the top and bottom boundaries of the new documown below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    19/63

    fore going any further lets duplicate the layer and hide one of them by clicking on the visibility icon.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    20/63

    en lets distort the layer further as shown here so we get the appearance of perspective and also to adjust its size to what we want.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    21/63

    nce we have the image of the galaxy base setup lets create on top of it a new gradient layer.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    22/63

    ts choose for the gradient a standard white to transparent gradient, and for the first color to the left lets double click on it and select a blue color as shown below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    23/63

    ow lets setup the gradient to radial with an angle as shown here and while this dialog its open drag the center of the gradient to the center of the galaxy base.

    en set the scale to 127 and click OK. And now set this layer mode to overlay.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    24/63

    nd now lets distort the gradient layer itself to adjust its shape to our galaxy, so rasterize the layer and distort it as shown below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    25/63

    ext just create a clipping mask so the gradient affects only the galaxy base and then merge the two layers together.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    26/63

    ow create a layer mask for the resulting layer.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    27/63

    nd to proceed we will select a soft brush as shown below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    28/63

    en we will mask off sections of the galaxy as shown here to make it more dynamic and less disk like.

    ow before we move on we will duplicate the galaxy layer once we are happy with the mask and hide the original for safe keeping.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    29/63

    en on the visible galaxy layer right click on the mask thumbnail and select apply layer mask.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    30/63

    ow its time to start making this galaxy our own and unique at the same time so lets go to our smudge tool and set the brush size as shown below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    31/63

    e will start smudging some new flow and features to it as shown here.

    en lets reduce the size of the brush quite a bit and start working on more tiny detail all around the galaxy introducing new features and detail, but at the same time following the established f

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    32/63

    ere you can see what we are after by smudging our way through it, yet this is quite personal and its up to you how far we want to go here.

    ext up lets make a copy of our "safe" hidden layer, and once again apply the layer mask.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    33/63

    ow lets bring this new layer copy all the way to the top.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    34/63

    en apply a Gaussian blur filter to this layer with the settings shown here so we get the results below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    35/63

    so set this top layer to linear dodge.

    nd lets adjust the levels directly for this layer as shown here

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    36/63

    ere you can see the results of the process we have followed, looking quite nicely so far we have a detailed good looking galaxy base to work on.

    Step 2 Stars and Glow

    ow all galaxies are made up mostly of stars, of course every star has planets, yet what we visually see is the stars, hundreds of billions of stars. So to try and illustrate this we will need a specist for it that will help us paint all these stars without spending the rest of the decade making them. Lets make a new document as shown here, and fill it with black.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    37/63

    ow with this brush here and with 100% white we will click some defined dots randomly spread like shown below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    38/63

    ow lets drag a selection around these and invert the image so we get black dots on a white background.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    39/63

    ow just define the brush preset as shown here.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    40/63

    ow lets go back to our image and scroll down the brush list to find the new brush. Now lets setup the brush palette, first enabling scattering with the settings below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    41/63

    en enable shape dynamics with the pen pressure option and in the brush tip shape section lets adjust the settings as shown.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    42/63

    ow lets reduce the size of the brush a bit and start painting some stars in a new layer as shown below, that follow the flow of our galaxy. Dont mind the fait look they have now we will fix thcond.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    43/63

    nce we have covered the galaxy lets select the layer and duplicate it twice.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    44/63

    ou can see here the look of the stars gets intensified, now grab all the layer copies and merge them together.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    45/63

    ow we will randomly erase some of our stars by using the eraser and selecting for it a brush as shown below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    46/63

    ow just adjust the settings below in the brush tip shape section.

    nce we are happy and made the stars randomly distributed, lets duplicate the layer once more and merge them. My results are shown below, at this point you can erase a bit more if you like oe any patterns that never look good.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    47/63

    this image you can see the flow we are trying to enhance and accentuate by eliminating some of the stars.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    48/63

    ow we will start working on the central nucleus of stars. Every galaxy has its most accumulated stars in the center so for this lets make a new layer.

    e will now increase the brush a bit to make the stars more evident, and start working on the center of the galaxy building up the nucleus. You can disable the rest of the galaxy layer so you caore clearly what are you adding.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    49/63

    nce satisfied with what we have we will duplicate the layer 3 times and of course then merge them all.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    50/63

    ow we can move scale and distort this layer in place plus I also erased some of it shown in red below.

    ext up we will use the gradient tool and select the gradient I have included below and set it up to circular.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    51/63

    ow lets drag this from the center of the galaxy as shown here.

    ow setup this layer mode to hard light and you can see the results below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    52/63

    ow lets distort this gradient a bit so it fits nicely in our galaxy center.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    53/63

    ow in a new layer lets make another gradient, this time set the layer to linear light.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    54/63

    nd also distort it into place.

    ow if needed just soft erase any hard edges that the gradient gets.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    55/63

    ext just reduce this layer opacity to around 64%

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    56/63

    K then we will create a new layer on top and select an almost white blue color.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    57/63

    lect our custom star brush again and enable shape dynamics with the pen pressure setting enabled. Then paint a bunch of new stars to add to the center of the galaxy.

    ow grab a soft brush of about 50px and create a layer mask on this latest layer.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    58/63

    ow with black selected just mask off this layer as shown here, again following the flow of our spiral galaxy.

    eat, now lets make a duplicate of our original galaxy shape we have hidden

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    59/63

    ght click on the layer mask and select "apply layer mask" then drag it all the way up below our last layer.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    60/63

    nd set this layer mode to hue.

    ow we will alter this layer color by setting up the hue saturation as shown below.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    61/63

    is is the result we get so far.

    e will then add a layer mask here and make sure we have our soft brush still selected and at about 50px

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    62/63

    ow mask off this layer influence as shown just leaving some streams of this golden yellow hue. Adapt the brush size if you need.

    ow lets select a dark brown as shown here, and make our brush very small about 2 or 1 px.

  • 8/21/2019 Psd.tutsplus.com Tutorials Tutorials-effects Spiral-gala

    63/63

    nd then in a new layer lets paint some dark matter streams as shown here.
