			<content:encoded><![CDATA[<p>This week we&#8217;ve been making paper penguins.  Our reasoning isn&#8217;t quite as tenuous as you would imagine; our company mascot is a penguin, we had an hour to kill, and we needed something to put on the <a href="http://igloo.refreshcartridges.co.uk/">Refresh Cartridges blog</a>.</p>
<p>Of course, you never know where a journey to create a penguin template will take you and while looking for a free vector image editing program, Matt fortunately stumbled across the website www.aviary.com.  Aviary is essentially a free online design suite which consists of many powerful tools ranging from a simple audio editor to a variety of fairly sophisticated image/vector editing software.</p>
<p>The applications are all used online rather than being downloaded and installed on to your hard drive.  This offers a number of advantages, most notably the ability to &#8216;dip in&#8217; quickly and easily, without having to install, and the fact that everything is stored on a central server means you will always be using the most up to date version of the software.</p>
<p>The list of applications currently includes:</p>
<p><strong>Phoenix</strong> &#8211; A free image editor that handles pretty much anything from basic image retouching to complex effects.  Features include a wide selection of tools, support of layers and 72 helpful tutorials to get you up and running.</p>
<p><strong>Toucan</strong> &#8211; A colour editor which is ideally used in conjunction with other creations tools in the suite.  Toucan can be used to pick and analyse colour by either colour association rules or by grabbing colours from within existing images.</p>
<p><strong>Peacock</strong> &#8211; Described by its creators as a &#8216;visual laboratory&#8217;, Peacock is used to generate a whole host of effects and image manipulation tools to make some quite stunning and abstract artwork.</p>
<p><strong>Raven &#8211; </strong>This tool is used for generating vector artwork, which is used by artists to create images that are fully scalable and suitable for applications such as logos and t-shirt designs.  The intricacies of vector artwork are too deep to explain in one sentence but the bottom line is that rather than every pixel of an image being assigned a colour value, a vector image is saved using descriptions of the lines, curves and shapes making up the image.  This means that if the image has to be radically resized the descriptions of those shapes are just changed proportionally resulting in no loss of image quality.  Due to the restrictions of creating drawings using just shapes and lines, vector images are typically quite simple.</p>
<p><strong>Falcon</strong> &#8211; This utility is used to capture images and web pages quickly and easily in order to crop, resize and ultimately save them for use in another package.  A similar utility <strong>&#8216;Talon&#8217;</strong> on the site allows you to do the same with an complete computer screenshot.</p>
<p><strong>Myna</strong> &#8211; Use Myna to edit and remix music tracks and audio clips.  The application can be used to trim, loop, stretch and reverse audio clips along with adding fade ins, fade outs and other effects such as pitch change, delay and reverb.<br />
Each of these tools is free to use and comes with at least one tutorial to help newcomers get to grips with how to use the software and what to use each program for.  Each program is free to use and advertising is nonexistent, however users do have the option for upgrading for just over £15 a year.  By paying for a subscription you are given a number of additional features such as unlimited storage of your creations online, the ability to add personalised watermarks to your creations and access to the advanced premium tutorials and forums.</p>

			<content:encoded><![CDATA[<p>A question I’m currently receiving on a weekly basis is ‘how many pictures will I be able to fit on this’ when a customer is referring to the size of memory card or USB Flash Drive.  Understanding image resolution and size is important in this digital age and although the intricacies are incredibly complex, the basics are pretty easy to get to grip with.<br />
<strong>What is Image Resolution?<br />
</strong>A pixel is a unit of programmable colour on a computers display and by combining many of them together we are able to create an image; the term resolution typically refers to the number of pixels that are used in this process.  On the whole, the quality of the image will increase with a greater number of pixels as we are able to store a greater amount of detail.</p>
<p><strong>How is Resolution Measured?<br />
</strong>Resolutions are generally expressed in two different formats &#8211; either the pixel dimensions of the image are given or the total number of pixels used in its creation.</p>
<p>Most digital cameras express their maximum resolution in terms of megapixels (millions of pixels) that can be used to create an image; an 8 mega pixel camera would be able to break a picture down in to 8 million pixels hence giving a higher resolution that a 5 mega pixel camera.</p>
<p>The resolution of a computer image on the other hand is usually expressed by giving the number of pixels present on a line and the number of lines used in the image.  For example, an image measuring 1600 x 1200 would contain 1600 pixels per line and a total of 1200 lines giving a total of 1,920,000 pixels (1.92 mega pixels).  As the image contains a greater number of horizontal than vertical pixels we can assume this picture would be landscape rather than portrait.</p>
<p><strong>How does Resolution affect File Size?</strong><br />
The more pixels an image contains the larger the file is likely to be; this is due to the fact that storing information relating to 10 million pixels is liable to require more space than saving a lower resolution 1 million pixel image.</p>
<p>There are several other very important factors to consider:</p>
<p>File Format – Over the years there have been many different image file formats, each introducing new advantages and disadvantages and covering them all would take an article in itself.  The two you are most likely to come in to contact with when using a digital camera are JPEG (smaller images that often include compression) or RAW (Completely unprocessed images files which are of a higher image quality but also substantially larger)</p>
<p>Colour Depth – Along with the total number of pixels that constitute an image, we also have to consider the potential number of colours each pixel could be.  If, for example you save your image as a ‘line art’ image where each pixel can be either black or white then the amount of data required to store this information is less than if you set a colour depth of ‘true colour’ where each pixel could be one of 16,777,216 potential colours.</p>
<p>Compression – Many image formats, such as JPEG allow you to adjust the amount of compression that is utilised when saving the image.  Compression can work in a number of different ways but ultimately it works to minimise the amount of data required to save the image.  This is usually achieved by looking for areas of commonality (for example a shape or pattern) and saving the description of that area which the computer can then later reproduce when reloading the image rather than defining each individual pixel.</p>
