Photoshop Video Tutorials On File FormatsPhotoshop files themselves cant be embedded into a web page. You will need to export your file and save it in a web-friendly format. There are three formats for web graphics: JPEGs, GIFs and PNGs.JPEG:The JPEG format (pronounced jay-peg), works best with photographic images or images that have more than 256 colors and gradients, such as the flowers.Images saved in JPEG format are compressed, which means that image information will actually be lost, causing the image to degrade in quality.JPEG Quality:Changing the value in the Quality drop-down box alters the level of compression for the image. Reducing the quality may result in blurring or pixelation, but too high a setting will produce a large file that will take users too long todownload.A good approach is to decrease the quality value gradually until you notice the degradation of your image becoming unacceptable. A reasonable compromise will be somewhere around this point.GIF:The GIF format (pronounced jiff or giff depending on which side of the tracks you grew up) can have a maximum of 256 colors.GIF files support transparency and animation, and work best with graphics that have large areas of the same color.PNG:The PNG format (pronounced ping) is similar to the GIF format in that it supports transparency and works best with solid-color images, but its superior to the GIF format as it has the ability to support true levels of transparencyfor colored areas.Transparent PNGs are currently not in widespread use on the Web because older versions of Microsoft Internet Explorer do not support them; however, theyre often used in Macromedia Flash movies. PNGs can produce a better quality image at a smaller file size than can GIFs.Photoshop allows you to save an image as a PNG-8 file (which works the same way as a GIF would with 256 colors) or a PNG-24 file (which allows for millions of colors as well as variable transparency).GIF/PNG-8 Colors:Adjusting this setting reduces the number of colors used in any image. This will usually make the biggest difference in the final image. dither amount and type (No Dither, Diffusion, Pattern, Noise)This setting has nothing to do with being nervous or agitated. Dither refers to a compression technique in which the pattern of dots is varied to give the illusion of a color gradient. Changing the dither will result in a more noticeable degradation for images that involve a large number of colors blended together.

Notebook For The Casual User

Notebook For The Casual User

The notebook has a great deal of features, but what you use it for greatly affects the type that you should purchase. The device is designed to be compact, transportable and still provide all the technological requirements that suit your needs. Certain elements affect these notebook features a great deal. Many are unnecessary if you want to use the device only for fun or for occasional use, and others are also essential. It is important that you know what you need so that you can make sure your notebook is a sound investment.A recreational notebook user wants a device to be able to edit video, play DVDs, access the internet for browse and downloading games. For these requirements an internal CD/DVD will be required. These can be bought as an accessory, but if entertainment is the key requirement then it makes sense to buy one with inbuilt capabilities. This will provide instant access, making the device more readily accessible and less cumbersome for the recreational user. The inbuilt DVD player will make the notebook heavier. The size of the notebook screen will affect the quality of the entertainment used. A larger screen is required to make the image clearer and more enjoyable. This will make the device bulkier and heavier, but if it used for recreational reasons, then this is seldom a problem. A fifteen to seventeen inch screen is perfect for the recreational user. This also means that the keyboard will be larger which can assist with gaming in terms of better and easier access to controls. The graphics card needs to be able to produce a good quality image on these screens, and so choose a notebook compatible 3d option. If it is inbuilt, check to make sure it is top of the range to avoid disappointment. Any notebook has built in memory that can easily cope with an excess of word processing and document creation and storage. However, if you are using it for entertainment, then the size of the memory will be important. The bigger the memory; the best quality product you will receive. The memory affects picture quality, game choice, graphics, and game speed. If any of these are a requirement then you should choose a notebook with maximum memory to get the best possible results. If you are using a video card that says `Shared Video Memory` then this means that it uses some memory from your notebook. Small amount of memory also restricts the number of colours available and so again it will produce an image of low quality.Downloading films and games from the internet require good hard disk space also. Many games are multi faceted and so require regular saving. These store lots of information including graphics, and so try to keep the amount to a minimum to get the best performance from your notebook. Games on disc use less memory, and so combine the use of the two for better variety. Add and remove downloaded films as required to get the best from your device. This is also important for the battery life. Using a notebook recreationally runs the battery down much more quickly than for business use. The more information stored, the more output is expected, and so the battery will take the strain. Keeping a neat and well organised notebook will ensure you get optimum performance.

Battery Life - Expectations

Battery Life - Expectations

The life of a battery bloc can vary dramatically especially when used in a UPS System , the manufacturer will always state the expected life of a battery bloc on the proviso that it has a pure dc float voltage applied to it and that the ambient temperature is restricted to 20 C. If these parameters are adhered to, one can expect to achieve the 5 years life from a 3 5 year design life battery or the 10 years of a 7 10 year design life battery bloc, omitting manufacturing failures.Unfortunately we do not live in a perfect world and as a result there are limitations applied to the battery bloc, one is the ambient temperature, although a number of rack-mounted UPS systems may luxuriate in ambient temperatures of 20 C or less because of the demands of the IT equipment, due to the nature of the design of the UPS there is generally insufficient space to achieve a significant airflow round the battery blocs and as a result they will fail the UPS system battery test after a mere 2 3 years.In this situation the requirements of Uninterruptible power supplies and their installation mean that UPS maintenance is unlikely to detect the failure of the battery pack, often due to the fact that after a very short period of time the UPS system is hidden in a mass of communication cables. The most positive approach under these circumstances is to rigorously implement a two-year replacement battery programme to ensure the integrity of the backup UPS system. This also applies to Generators. Yes, even diesel generators require batteries to supply the current to start.Flat or failed batteries render the generator useless. Call outs to such problems are chargeable and yet can be avoided by a regular maintenance regime.In larger UPS systems the problems arising are often due to location; no-one wants the local radiated noise of Uninterruptible power supplies to impinge on their working environment and, as a result the uninterruptible power supply will be located in a basement perhaps, where the ambient temperature is not ideal for batteries and maybe the saying, Out of sight is Out of mind, is true. In the case of battery life, ignorance is not bliss. Batteries will fail the question is whether you are prepared or just waiting for it to happen,As a result of the location the ambient temperature can often exceed 25 - 30 C and this potentially could decrease the expected life of the battery. For, prolonged use at 30 of VRLA (valve regulated lead acid) batteries the expected life can decrease by 50%, if the ambient temperature is raised to 40 C the life of the battery will fall by another 50%. Therefore at an ambient temperature of 40 C the expected operating life of a 7 10 year life battery has fallen to 1.75 2.5 years!In this case even UPS maintenance will not save the battery, all it can do is to report on the rapid deterioration of the battery bloc.Fortunately these extremes covered by these scenarios are not too common but they highlight the need to record the operating conditions by regular UPS maintenance and to ensure that there is an emergency 24/7 callout cover in place in the event of the unexpected happening. Be prepared!

Security Cameras: Choices For Home And Office Security

If youre shopping for security cameras, take note of the following:Wide Angle Cameras for Larger SpacesInside your shop or bar, you need a camera for interior surveillance. A wide angle camera will record wider areas, which is important to keep close watch over everything.Opt for color cameras because these will show more detail, such as color of hair and clothes worn by the subject. Combined with the face shot, your details are excellent.Bullet and Dome Security CamerasBoth types can be used outdoors and indoors. These are also available in black and white (B&W) or color. Color cameras are a bit expensive, so if budget is tight, get the B&W.Having these B&W security cameras is better than agonizing each day about your home and office security. At least, B&W cameras have higher resolutions in lower light. Meaning they can see better in areas with less light. For a dimly-lit bar, this is ideal.Pan-Tilt Zoom CamerasA pan-tilt camera has the flexibility to see around your surveillance area. You can pan the entire section, look up and down, and zoom in on anything that catches your attention. Everything within the seeing scope of the lens will be captured. You can also set these cameras on manual or automatic or on both modes.On automatic mode, the camera can follow the set hundreds of points. The duration the camera focuses on a given set point can be regulated. Find out the variances of the zooms of the different models before deciding on your pan tilt security cameras.Other Types of Security CamerasIf you wish to frighten off interlopers, fool them with fake surveillance cameras.

Ipod And Itunes - Friends Or Foes?

Despite how user friendly iTunes is, it can nonetheless prove a real threat to the music collection stored on your iPod. Before saying anything else, rest assured that there are steps you can take to essentially eliminate this risk, but if you keep the default iTunes settings, the risk will remain.The first impression iTunes gives is that of a very simple and easy to use software to buy music online. It also servers as a library with a huge amount of music data as well as the primary application through which you manage you iPod. Before that slick interface, however, lies cutting-edge encryption, authentication and digital rights management technology (DRM) that tries to make sure that what you download and play on your iPod is actually paid for!Apart from Apple's own DRM restrictions, iTunes seems to do everything in it's power to make sure you loose your music collection. Here is a list of dangerous iTunes behaviors and settings.AutomationEven if you are a complete beginner using PCs or an iPod, you should never, ever allow for automatic synchronization between your iTunes' music library and the library stored on your iPod. You see, an iPod can only be tied to a single iTunes library, at least in terms of synchronization. Hence, if you connect your iPod to a friend's computer (or vice versa) and iTunes starts synchronizing the two libraries, all content on the iPod will be lost! To avoid that, go to Edit - Preferences - iPod and select Manual Synchronization.iPod is not a BackupMany people think that their iPod also acts as a back-up of their music collection. Guess again. Data transfer always happens from your computer to your iPod and not the other way around. So, in the unfortunate event that you computer's hard disk fails and you loose your iTunes library, you can't restore your tracks from an iPod.3rd Party SolutionsLucky for us, the huge user base of iPod and iTunes as well as the flexible design of the iPod's operating system have allowed for the creation of 3rd party programs that can help you better manage your iPod music library. SharePod, for example, is a very simple end easy to use application that allows you to transfer songs from your iPod to your PC (and vice versa), manage your iPod playlists, share your iPod tracks across a network and much more. Anapod explorer is a similar application that also allows you to manage photos, notes and contacts, as well as convert music tracks to different file formats.
