Portable scanners are very small and often are fitted into a computer mouse. These are good for traveling with and have multiple function. However, these are the lowest detailed scanner of the types and will generally be the cheapest.A scanner works by shining a light to illuminate the page and then a scanner head moves across the work that is being scanned to capture the reflected light. The computer will read the information as digital code and can then transform the code into pixels and display them on your screen.
A digital camera is much the same as a normal camera which captures an image for you. The difference between a digital camera and a standard camera is that a digital camera will convert the image that you have captured and store it as digital data rather than on film. The images are captured using the sensor built into the camera. This is done by capturing the light and converting them into electrical charges which are used to calculate the pixels of an image to be stored in the cameras memory stick. Meaning that the main difference in most digital cameras will be down to the size and power of the sensor in the camera.Obviously the quality of the images captured will greatly change the price of the camera which can make them cost between £50 - £7000 depending on the quality of the camera. The price can also vary on its ability to change lenses, the power of its original lens in particular, the flash can be changed on the camera, and also the SD card that it comes with.
A graphics tablet is used in many artistic related jobs such as Concept artists, because it allows you to draw a picture as if you were drawing it on paper but it will convert the image directly onto the computer through programmes such as Photoshop. The cheapest form of graphics tablets have a non-pressured screen, which for doing official concept works is not good enough, but can be fine for those who just want a tablet for free time. The mid range graphics tablet are still relatively cheap, and can be around £50-£100 which will come with a pressured screen. A pressured screen will detect how hard or soft you press down with the pen and will change how your drawing comes out accordingly. The final type of graphics tablet actual uses a pressured screen. This means that the image you are drawing onto your computer is actually also projected onto the screen of your tablet which allows much easier work and also has the pressure sensitivity stated in the previous version. However, these are industry standard and a most like going to set you back roughly upwards of £1000. But with the price you pay you can expect good results.Digital graphics optimisation refers to how you can get the best possible outcome from your digital image. For instance when creating a poster for use outside, a TIFF file would likely be used as this is printable, is incredibly highly quality and can print in RGB.
However, if creating an image for use on a website a TIFF file would not be useful as the image size would be so big that many people would not be able to download the image quick enough and so a much smaller sized file would need to be used for a much smoother experience.
Asset management software is a tool that many organisations use for the storage, management and distribution of media. This includes things such as photos, music, videos and many other multimedia content. Each piece of stored data will be kept track of through records which display the name of the file, its format and information about when it was last modified and from what location. This means that you can keep track of all your pieces of work. This could be useful for many artists as it organises your pieces very neatly and allows a huge storage space for all of your piece of works.
