<p>Ever tried to take a snap at the moon? The results without a NASA-like telescope are pretty frustating. With Photoshop we&#8217;ll be able to blend NASa pretty images ofthe moon within our photos.</p>
<p><span id="more-61"></span> This tutorial is aimed to people with minimum knowledge of Photoshop. Shall there be any question, let me know.</p>
<p>First of all you&#8217;ll need a ptoho to work with and <a target="_blank" href="http://images.google.es/images?q=moon&#038;svnum=10&#038;um=1&#038;hl=es&#038;sa=X&#038;imgsz=xxlarge">an image of the moon</a>.</p>
<p>How to work with the moon</p>
<p><a class="imagelink" title="a01.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a01.jpg" /></p>
<div style="text-align: center"><a class="imagelink" title="a01.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a01.jpg"><img id="image62" alt="a01.jpg" src="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a01.miniatura.jpg" /></a></div>
<p>This photo&#8217;s problem is that it&#8217;s daytime! I&#8217;ll add a Hue/Saturation layer to darken it and take saturation out.</p>
<p>Then i&#8217;ve selected a color range with the sea highlights and I&#8217;ve filled a new layer with those.</p>
<p><a class="imagelink" title="a02.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a02.jpg" /></p>
<div style="text-align: center"><a class="imagelink" title="a02.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a02.jpg"><img id="image63" alt="a02.jpg" src="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a02.miniatura.jpg" /></a></div>
<p>Well, to the moon! You should cut out the background and add a couple of radial gradients for the halo. Make it brighten by reducing its opacity.
</p>
<p align="center"><a class="imagelink" title="a03.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a03.jpg"><img id="image64" alt="a03.jpg" src="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a03.miniatura.jpg" /></a> <a class="imagelink" title="a04.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a04.jpg"><img id="image65" alt="a04.jpg" src="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a04.miniatura.jpg" /></a></p>
<p>Put the moon on the desiered position and  add a Hue/Saturation layer on the top with colorize option set and tune the hue as you like. </p>
<p><a class="imagelink" title="a05.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a05.jpg" /></p>
<div style="text-align: center"><a class="imagelink" title="a05.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a05.jpg"><img id="image66" alt="a05.jpg" src="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a05.miniatura.jpg" /></a></div>
<p>It can be improved by copying the rocks from the background into a new layer behing the hue/saturation. Also a few fog will do fine. Just blur some white gradients.</p>
<p><a class="imagelink" title="a06.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a06.jpg" /></p>
<div style="text-align: center"><a class="imagelink" title="a06.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a06.jpg"><img id="image67" alt="a06.jpg" src="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/a06.miniatura.jpg" /></a></div>
<p>Another photo. It&#8217;s sunset and I like the colors but there are trees.</p>
<p><a class="imagelink" title="b01.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b01.jpg" /></p>
<div style="text-align: center"><a class="imagelink" title="b01.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b01.jpg"><img id="image68" alt="b01.jpg" src="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b01.miniatura.jpg" /></a></div>
<p>To dakrness it I&#8217;ve just used a black radial gradient and I&#8217;ve placed the moon I&#8217;ve worked with before.</p>
<p><a class="imagelink" title="b02.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b02.jpg" /></p>
<div style="text-align: center"><a class="imagelink" title="b02.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b02.jpg"><img id="image69" alt="b02.jpg" src="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b02.miniatura.jpg" /></a></div>
<p>The trees are suposed to be in front of the moon. I&#8217;ll select a color range of the trees and I fill a new layer with black using the selecion.<br />
<a class="imagelink" title="b03.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b03.jpg" /></p>
<div style="text-align: center"><a class="imagelink" title="b03.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b03.jpg"><img id="image70" alt="b03.jpg" src="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b03.miniatura.jpg" /></a></div>
<p>Here comes in hand the smart object as I decide to make the moon greater and bloodier. The color is archieved with a new layer within the smart object.</p>
<p><a class="imagelink" title="b04.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b04.jpg" /></p>
<div style="text-align: center"><a class="imagelink" title="b04.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b04.jpg"><img id="image71" alt="b04.jpg" src="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b04.miniatura.jpg" /></a></div>
<p>I wanted to add some fog interacion. But there ain&#8217;t raytrace. What I do is increase canvas size from the left and top in order to center the moon. I draw a radial gradient in a new layer and I erase the black areas from the tree layer. The key is a radial blur filter. Then the image is cropped back to its size.</p>
<p><a title="b05.jpg" class="imagelink" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b05.jpg" /></p>
<div style="text-align: center"><a title="b05.jpg" class="imagelink" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b05.jpg"><img alt="b05.jpg" id="image74" src="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b05.miniatura.jpg" /></a></div>
<p>And It&#8217;s done. Beware that this layer must have a mask limiting it to the tree zones.</p>
<p><a class="imagelink" title="b06.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b06.jpg" /></p>
<div style="text-align: center"><a class="imagelink" title="b06.jpg" href="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b06.jpg"><img id="image73" alt="b06.jpg" src="http://josep.valls.name/wordpress/wp-content/uploads/2007/05/b06.miniatura.jpg" /></a></div>
