										<content:encoded><![CDATA[<p>Mixing day and night images with the technique in astrophotography known as &#8216;star trails&#8217; it is possible to capture a single image detailing both day and night activity. In the photograph below to the left is the moon streaking across the scene and the lights of aircraft at night, to the right is the sun with traffic captured below. Depending on your location the technique can create some interesting timelapse single views photographs, below we detail how to create your own.</p>
<div style="clear: both; text-align: center;"><a href="https://lh6.googleusercontent.com/-RhBn6ggSFTk/TXPI1uME1II/AAAAAAAACd4/Sfa1P6fnw80/s1600/city3.jpg" style="margin-left: 1em; margin-right: 1em;"><img fetchpriority="high" decoding="async" border="0" height="480" src="https://lh6.googleusercontent.com/-RhBn6ggSFTk/TXPI1uME1II/AAAAAAAACd4/Sfa1P6fnw80/s640/city3.jpg" width="640" /></a></div>
<p><b>You will need:</b></p>
<p>1 x Timelapse System, you can use a simple webcam as per our previous <a href="http://digitalurban.blogspot.com/2008/11/tutorial-torch-webcam-hd-timelapse.html"><span>Tutorial: Torch + Webcam = HD Timelapse System</span></a> a DSLR such as the <a href="http://digitalurban.blogspot.com/2009/12/canon-g9-timelapse-1080p-with-chdk.html"><span>Canon G9 with CHDK </span></a>, a <a href="http://digitalurban.blogspot.com/2010/02/timelapse-on-iphone-look-at-free.html"><span>iPhone with the free Gorrilacam app</span></a> or any camera that can take photos at regular intervals. We used a Go Pro HD camera in timelapse mode, taking a picture every 5 seconds.</p>
<p>1 x Copy of Photoshop, you can <a href="http://www.adobe.com/products/photoshop/compare/"><span>download a 30 day trial</span></a>.<br />1 x Photoshop <a href="http://www.schursastrophotography.com/software/photoshop/Startrails.atn">Stacking Action</a> (thanks to <a href="http://www.schursastrophotography.com/index.html">Deep Space Astrophotography</a></p>
<p><b>Time Taken, 4 to 12 hours to capture, 2 to 6 hours to process.</b></p>
<p>The concept is simple, set up your camera, webcam or iphone at a suitable location, and capture an image at regular intervals, for our example we captured an image every 5 seconds pointing at the skyline of London. Capturing an image at least every 5 seconds is vital for star/aircraft trails as it allows for closer spacing between the lights in the final image.</p>
<p>We left the camera running for approximately 12 hours capturing 8000+ images, saved into a folder on our computer. Ours captured covered both day and night time, resulting in the following timelapse:</p>
<div></div>
<div><center><iframe allowfullscreen="" frameborder="0" height="390" src="http://www.youtube.com/embed/QPUYKg30SSA" title="YouTube video player" width="640"></iframe></center></p>
<p>The next step is to open up photoshop, chose the images you want to use, and start stacking.</p>
<p><b>Image Stacking in Photoshop</b><br /><b><br /></b><br />The images will be stacked onto of an intially blank image via a simple automated action:</p>
<div>1) Create a new blank black image the same size are your captured photographs.</div>
<div>2) Load the action into the action windows in Photoshop and load the action Startrails.atn.<br /><span style="color: #222222; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 15px; line-height: 21px;"><br /></span></p>
<div style="clear: both; text-align: center;"><span style="color: #222222; font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 15px; line-height: 21px;"><a href="http://2.bp.blogspot.com/_ADwvfqkxChw/S4Jc0yTcnjI/AAAAAAAACU4/JHAhRr80DMc/s1600-h/loadaction.jpg" style="color: #2288bb; margin-left: 1em; margin-right: 1em; text-decoration: none;"><span style="font-family: Arial, Helvetica, sans-serif;"><img decoding="async" border="0" height="327" src="http://2.bp.blogspot.com/_ADwvfqkxChw/S4Jc0yTcnjI/AAAAAAAACU4/JHAhRr80DMc/s400/loadaction.jpg" style="-webkit-box-shadow: rgba(0, 0, 0, 0.0898438) 1px 1px 5px; background-attachment: initial; background-clip: initial; background-color: white; background-image: initial; background-origin: initial; background-position: initial initial; background-repeat: initial initial; border-bottom-style: solid; border-color: initial; border-color: initial; border-color: initial; border-left-color: rgb(238, 238, 238); border-left-style: solid; border-right-color: rgb(238, 238, 238); border-right-style: solid; border-top-color: rgb(238, 238, 238); border-top-style: solid; border-width: initial; border-width: initial; border-width: initial; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px; position: relative;" width="400" /></span></a></span></div>
</div>
<div></div>
<div><span><br /></span>3) In Photoshop click &#8216;File&#8217;, &#8216;Automate&#8217; and &#8216;Batch&#8217;. Select the action you have just loaded and choose your directory with the images as source and make sure you select &#8216;None&#8217; for the output directory.</div>
<div></div>
<div>Click &#8216;Ok&#8217; and leave it running, our Mac laptop took around an 2 hours to stack the images &#8211; resulting in the Star/Aircraft Trail&#8217; below:</div>
<div>
<div style="clear: both; text-align: center;"><a href="https://lh4.googleusercontent.com/-2Qo3_Dq_R5E/TXPLF0DtzGI/AAAAAAAACeM/FUNs6EXSHi8/s1600/city4.jpg" style="margin-left: 1em; margin-right: 1em;"><img loading="lazy" decoding="async" border="0" height="480" src="https://lh4.googleusercontent.com/-2Qo3_Dq_R5E/TXPLF0DtzGI/AAAAAAAACeM/FUNs6EXSHi8/s640/city4.jpg" width="640" /></a></div>
<p></div>
<div>The line across the centre is a star and the bright line on the left is the moon coming into shot. The rest of the lights are aircraft in the sky above London. If you use a complete day/night sequence then you can create images of stars/activity in a blue sky, as in our first photograph.</div>

										<content:encoded><![CDATA[<p>Last week we covered creating &#8216;day trails&#8217; in Photoshop using the technique in Astrophotography known as &#8216;star trails&#8217;. Today we take the same technique and use it to create a view of city activity at night.</p>

										<content:encoded><![CDATA[<p>Last week we covered creating &#8216;day trails&#8217; in Photoshop using the technique in Astrophotography known as &#8216;star trails&#8217;. Today we take the same technique and use it to create a view of city activity at night.</p>
<p><a href="http://1.bp.blogspot.com/_ADwvfqkxChw/S4-UeWg4qNI/AAAAAAAACVY/y2muKeYtBjg/s1600-h/nightlights.jpg" style="margin-left: 1em; margin-right: 1em;"><img loading="lazy" decoding="async" src="http://1.bp.blogspot.com/_ADwvfqkxChw/S4-UeWg4qNI/AAAAAAAACVY/y2muKeYtBjg/s640/nightlights.jpg" border="0" height="160" width="600" /></a><b></p>
<p>You will need:</b></p>
<div style="text-align: center;"></div>
<p>1  x Timelapse System, you can use a simple webcam as per our previous <a href="http://digitalurban.blogspot.com/2008/11/tutorial-torch-webcam-hd-timelapse.html">Tutorial:   Torch + Webcam = HD Timelapse System</a> a DSLR such as the <a href="http://digitalurban.blogspot.com/2009/12/canon-g9-timelapse-1080p-with-chdk.html">Canon  G9 with CHDK </a>, a <a href="http://digitalurban.blogspot.com/2010/02/timelapse-on-iphone-look-at-free.html">iPhone  with the free  Gorrilacam app</a> or any camera that can take photos at  regular intervals. We used a Go Pro HD camera in timelapse mode, taking a picture every 5 seconds.</p>
<p>1 x Copy of Photoshop, you can <a href="http://www.adobe.com/products/photoshop/compare/">download a 30  day trial</a>.</p>
<p>1 x Photoshop <a href="http://www.schursastrophotography.com/software/photoshop/Startrails.atn">Stacking  Action</a> (thanks to <a href="http://www.schursastrophotography.com/index.html">Deep Space  Astrophotography</a>)</p>
<p>Time Taken, 4 to 12 hours to capture, 2 to 6 hours to process.</p>
<p><b>Setting Up</b></p>
<p>The concept is simple, set  up your camera, webcam or iphone at a suitable location, and capture an  image at regular intervals, for our example we captured an image every 5  seconds pointing at the skyline of London. Capturing an image at least every 5 seconds is vital for star/aircraft trails as it allows for closer spacing between the lights in the final image.</p>
<div style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/_ADwvfqkxChw/S4-UzFkENgI/AAAAAAAACVc/ycg4PX6dCuQ/s1600-h/7240.JPG" style="margin-left: 1em; margin-right: 1em;"><img loading="lazy" decoding="async" src="http://2.bp.blogspot.com/_ADwvfqkxChw/S4-UzFkENgI/AAAAAAAACVc/ycg4PX6dCuQ/s640/7240.JPG" border="0" height="480" width="640" /></a></div>
<p></p>
<div style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/_ADwvfqkxChw/S4JZcIk-_gI/AAAAAAAACU0/15Mo6fmbCfE/s1600-h/nonstacked.jpg" style="margin-left: 1em; margin-right: 1em;"><br /></a></div>
<p>We left the camera  running for approximately 12 hours capturing 8000+ images, saved into a folder on our  computer. Ours captured covered both day and night time, resulting in the following timelapse:</p>
<p><center><object height="345" width="600"><param name="movie" value="http://www.youtube.com/v/QPUYKg30SSA&#038;hl=en_US&#038;fs=1&#038;"><param name="allowFullScreen" value="true"><param name="allowscriptaccess" value="always"><embed src="http://www.youtube.com/v/QPUYKg30SSA&#038;hl=en_US&#038;fs=1&#038;" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" height="345" width="600"></embed></object></center></p>
<p>The next step is to open up photoshop, chose the images you want to use,  and start stacking.</p>
<p><b>Image Stacking in Photoshop</b></p>
<p>The images  will be stacked onto of an intially blank image via a simple automated  action:</p>
<p>1) Create a new blank black image the same size are your  captured photographs.</p>
<p>2) Load the action into the action windows  in Photoshop and load the action Startrails.atn.</p>
<div style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/_ADwvfqkxChw/S4Jc0yTcnjI/AAAAAAAACU4/JHAhRr80DMc/s1600-h/loadaction.jpg" style="margin-left: 1em; margin-right: 1em;"><img loading="lazy" decoding="async" src="http://2.bp.blogspot.com/_ADwvfqkxChw/S4Jc0yTcnjI/AAAAAAAACU4/JHAhRr80DMc/s400/loadaction.jpg" border="0" height="327" width="400" /></a></div>
<p>3)  In Photoshop  click &#8216;File&#8217;, &#8216;Automate&#8217; and &#8216;Batch&#8217;. Select the action you have just  loaded and choose your directory with the images as source and make sure  you select &#8216;None&#8217; for the output directory.</p>
<p>Click &#8216;Ok&#8217; and leave  it running, our Mac laptop took around an 2 hours to stack the images &#8211;  resulting in the  Start/Aircraft Trail&#8217; below:</p>
<div style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/_ADwvfqkxChw/S4-V8F8y5mI/AAAAAAAACVk/ejX5nUaq4uU/s1600-h/CityLightsGoPro.jpg" style="margin-left: 1em; margin-right: 1em;"><img loading="lazy" decoding="async" src="http://4.bp.blogspot.com/_ADwvfqkxChw/S4-V8F8y5mI/AAAAAAAACVk/ejX5nUaq4uU/s640/CityLightsGoPro.jpg" border="0" height="480" width="600" /></a></div>
<p>The line across the centre is a star and the bright line on the left is the moon coming into shot. The rest of the lights are aircraft in the sky above London.</p>

										<content:encoded><![CDATA[<p>Photographer Salman Ashrafi notes that in today&#8217;s world, depending on what we do, we rarely find the time to just sit and observe everything that goes on around us. His movies, known as &#8216;Fotografic Memories&#8217; represent Salmans&#8217; work to make up for this loss of time and we really like his technique of combining frames with timelapse and music as the first example below of Toronto demonstrates:</p>
<p><center><object width="601" height="338"><param name="allowfullscreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="movie" value="http://vimeo.com/moogaloop.swf?clip_id=4678536&#038;server=vimeo.com&#038;show_title=1&#038;show_byline=1&#038;show_portrait=0&#038;color=b75957&#038;fullscreen=1" /><embed src="http://vimeo.com/moogaloop.swf?clip_id=4678536&#038;server=vimeo.com&#038;show_title=1&#038;show_byline=1&#038;show_portrait=0&#038;color=b75957&#038;fullscreen=1" type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="601" height="338"></embed></object></p>
<p><a href="http://vimeo.com/4678536">Downtown Toronto</a> from <a href="http://vimeo.com/fotograficmemory">Fotografic Memory</a> on <a href="http://vimeo.com">Vimeo</a>.</p>
<p></center></p>
<p>The technique and concept can be adapted to any situation &#8211; below is the &#8216;memory&#8217; of a bus ride in London comprised of 738 photographs:</p>
<p><center><object width="601" height="338"><param name="allowfullscreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="movie" value="http://vimeo.com/moogaloop.swf?clip_id=8315104&#038;server=vimeo.com&#038;show_title=1&#038;show_byline=1&#038;show_portrait=0&#038;color=ff0000&#038;fullscreen=1" /><embed src="http://vimeo.com/moogaloop.swf?clip_id=8315104&#038;server=vimeo.com&#038;show_title=1&#038;show_byline=1&#038;show_portrait=0&#038;color=ff0000&#038;fullscreen=1" type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="601" height="338"></embed></object></p>
<p><a href="http://vimeo.com/8315104">BUS RIDE</a> from <a href="http://vimeo.com/fotograficmemory">Fotografic Memory</a> on <a href="http://vimeo.com">Vimeo</a>.</p>
<p></center></p>
<p>Finally, Building and Clouds &#8211; Dubai:</p>
<p><center><object width="601" height="338"><param name="allowfullscreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="movie" value="http://vimeo.com/moogaloop.swf?clip_id=9287543&#038;server=vimeo.com&#038;show_title=1&#038;show_byline=1&#038;show_portrait=0&#038;color=b75957&#038;fullscreen=1" /><embed src="http://vimeo.com/moogaloop.swf?clip_id=9287543&#038;server=vimeo.com&#038;show_title=1&#038;show_byline=1&#038;show_portrait=0&#038;color=b75957&#038;fullscreen=1" type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="601" height="338"></embed></object></p>
<p><a href="http://vimeo.com/9287543">BUILDINGS + CLOUDS</a> from <a href="http://vimeo.com/fotograficmemory">Fotografic Memory</a> on <a href="http://vimeo.com">Vimeo</a>.</p>

										<content:encoded><![CDATA[<p>This is a nice concept &#8211; taking photos of  things you &#8216;notice&#8217; and uploading them to flickr with the tag &#8216;<strong style="font-weight: normal;">noticings&#8217; and a geolocation</strong>. Noticings are interesting things that you stumble across when out and  about.</p>
<p><a href="http://noticin.gs/"><img decoding="async" style="display: block; margin: 0px auto 10px; text-align: center; cursor: pointer; width: 600px; height: 183px;" src="http://www.casa.ucl.ac.uk/andy/blogimages/notice.jpg" alt="" id="BLOGGER_PHOTO_ID_5433980171426771874" border="0" /></a></p>
<p>In short, Noticings is basically a game about learning to look at the world around you, as their site states &#8211; Cities are wonderful places, and everybody finds different things in them. Some of us like to take pictures of interesting, unusual, or beautiful things we see, but many of use are moving so fast through the urban landscape we don&#8217;t take in the things around us.</p>
<p>You need a camera, and a way of recording where a photo was taken. That might be adding it by hand to the image within Flickr, or it might be a GPS. The ideal device to play Noticings is a camera with GPS built-in, such as the camera on a Smartphone like an iPhone or Android device.</p>
<p>Head over to <a href="http://noticin.gs/">http://noticin.gs/</a> to take part, we like it a lot!</p>
