			<content:encoded><![CDATA[<p>In this tutorial I’ll show how I processed this image using the easiest way to darken the sky for dramatic effect and some super-sharpening to bring out more detail in the photo.</p>
<p><img src="http://lukeroberts.us/wp-content/uploads/2008/06/small-looming.jpg" width="550" height="367" alt="Final photo" /></p>
<p>The photo I started with was okay, but nothing particularly interesting. The exposure was good, but the real scene was more dramatic. I’ve tried to recreate that scene the way I saw it. And, admittedly, enhance it to the way I wish I had seen it.</p>
<p><img src="http://lukeroberts.us/wp-content/uploads/2008/06/a_photo.jpg" width="550" height="367" alt="Original photo" /></p>
<h2>Step One – Shadows/Highlights</h2>
<p><strong>Duplicate the photo layer.</strong> Photoshop doesn’t yet have the ability to have Shadows/Highlights as an Adjustment Layer, so I like to keep a backup of the original photo for fine-tuning later on.</p>
<p><img src="http://lukeroberts.us/wp-content/uploads/2008/06/b_shadhigh.jpg" width="550" height="615" alt="Shadows Highlights tool" /></p>
<p>To give it a bit more of an HDR look (which is how our eyes see), I used the <strong>Shadows/Highlights tool</strong> . I kept the settings subtle to just bring a bit more detail into the clouds and to brighten the dark areas of the road and trees.</p>
<h2>Step Two – Darken the Sky</h2>
<p>Ensure your foreground colour is set to Black (<strong>press D</strong> to reset the colours to their <strong>D</strong>efaults)</p>
<p><img src="http://lukeroberts.us/wp-content/uploads/2008/06/c_gradient.jpg" width="550" height="408" alt="Gradient layer" /></p>
<p>Now add a <strong>Gradient Adjustment Layer</strong> . Set the gradient to “Foreground to Transparent”. I want the gradient to be going from black at the top to transparent at the bottom, so I’ve ticked “Reverse”.</p>
<p>Set this Adjustment Layer to <strong>Soft Light blend mode</strong> and now we have a nice dark sky. A similar effect could have been done by using a <a href="http://en.wikipedia.org/wiki/Graduated_ND_filter">Graduated Filter</a> on the camera when taking the photo, but a) I like the control and fine-tuning this offers and b) I don’t have a graduated filter (at least not one that fits my main lens).</p>
<h2>Step Three – Super-Sharpen</h2>
<p>Finally, to give the image more impact, I used some super-sharpening. My preferred method of sharpening (everyone seems to have their own way) is using the <strong>High Pass filter</strong>.</p>
<p>To use this, I needed to first flatten the image into a new layer above all the others (<strong>Ctrl+Alt+Shift+E</strong> – a very useful shortcut!).</p>
<p>Then to <strong>Filters &gt; Other (at the bottom) &gt; High Pass</strong>. The amount depends on the size of your photo and the effect you want. A small number (0.5 or 1) is good for normal sharpening. But for this super-sharpening effect, I went with 50.</p>
<p>Now, you should have a mostly grayscale image with a bit of smudged colour. I prefer to keep it all grayscale, but sometimes the extra colour looks good. To remove the colour I use <strong>Ctrl+Shift+U</strong>.</p>
<p><img src="http://lukeroberts.us/wp-content/uploads/2008/06/d_sharpen.gif" width="550" height="367" alt="Animated super-sharpen off and on" /></p>
<p>Set this layer to <strong>Hard Light blend mode</strong> to see how it looks. Now, turn the layer off and on a few times to compare. The unsharpened version almost looks blurry by comparison! The difference is dramatic. Some people will like it, others might think it’s too much. You can (and I usually do) turn the opacity down to keep it subtle.</p>
<p>I don’t usually use that super-sharpening but for this photo it seemed to work well. The method also works well on more texture based photos.</p>
<p>In my original I used my <a href="http://lukeroberts.us/2008/03/photoshop-quicktips-vintage-colours/">vintage colour technique</a> to adjust the colours further and tuned the opacity of layers to get it looking good to my eyes.</p>

<p>Hopefully this tutorial has given you a couple of new techniques to try out on your own photos. If you’ve used these techniques on one of your photos, I’d love to see what you have come up with – feel free to send me the link in the comments.</p>

<p>I was on /wg/ today and someone had posted a desktop screenshot, asking for the original wallpaper. At first glance, it just looked like a basic, pixelated image, but upon closer inspection, the pixels had rounded edges and a slight sharpening effect. The pixels were also on an angle, something not possible with the standard mosaic filter.</p>
<p>I looked at it for a while, wondering how it had been done, assuming it must have been a filter or maybe a script in GIMP. Since I had the original, unpixelated version, I thought I’d have a go at recreating the wallpaper for the person that had requested it.</p>
<p><span id="more-12"></span></p>
<p>The first thing I noticed was the angle of the pixels. I opened the screenshot in Photoshop and used the Ruler tool (I) to measure the angle. It was about 25 degrees.</p>
<p><a href="http://lukeroberts.us/wp-content/uploads/2008/03/2-originalimage.jpg"><img src="http://lukeroberts.us/wp-content/uploads/2008/03/2a-originalimage.jpg" width="468" height="198" title="Original wallpaper - click to download" alt="Original wallpaper - click to download"></a></p>
<p>I opened the original, unpixelated wallpaper and got started. Out of habit, I duplicated the layer (Alt+L+D) and took note of the image size (because we’ll be cropping it back to this size, later). This particular image is 2560&#215;1024 px (dual screen wallpaper).</p>
<p>The first step is to rotate the image -25 degrees to get the angled pixels. To do this, I went to Image > Rotate Canvas > Arbitrary (Alt+I+E+A) and entered -25 (Clockwise).</p>
<p><img src="http://lukeroberts.us/wp-content/uploads/2008/03/3-rotate.jpg" width="409" height="257" title="Rotate image" alt="Rotate image"></p>
<p>Now to add the pixel effect, I went to Filter > Pixelate > Mosaic. A value of 40 looked similar to the requested version.</p>
<p><img src="http://lukeroberts.us/wp-content/uploads/2008/03/4-mosail.png" width="362" height="587" title="Mosaic" alt="Mosaic"></p>
<p>After that, I needed to rotate the image back to it’s original level and crop the edges. To cancel the original rotation, I went back to arbitrary rotate and entered 25 (not minus) to get it straight. Then, I went to Image > Canvas Size (Ctrl+Alt+C) to crop it back to the original dimensions – 2560&#215;1024 – which I entered into the boxes.</p>
<p>The final step was the add the rounded/sharpened effect. I was stumped. Having come this far, though, I decided to experiment with some filters to see if I could get anything similar. I started looking through the filters and to my surprise, Paint Daubs worked perfectly. I had the settings of Brush Size: 8, Sharpness 4 and Brush Type: Simple.</p>
<p><a href="http://lukeroberts.us/wp-content/uploads/2008/03/5-paintdaubs.jpg"><img src="http://lukeroberts.us/wp-content/uploads/2008/03/5a-paintdaubs.jpg" width="464" height="284" title="Paint Daubs" alt="Paint Daubs"></a></p>
<p>In the image below you can see before the Paint Daubs effect and after.</p>
<p><img src="http://lukeroberts.us/wp-content/uploads/2008/03/6-beforeafter1.jpg" width="464" height="390" title="Before and after" alt="Before and after"></p>
<p>And that completes the effect. I’ve grown to quite like it. It’s close to the requested one, but not exact. I have no idea who made the original, but I’d love to know how they did it.</p>
