Image Capture:
Digital camera: Digital cameras have become better and more powerful with good optical lenses and high resolution. Picking a digital camera means finding the best mix of lens, price and the amount of mega pixels it has. The lens should allow you to control how much you want in the picture, this is called optical zoom. Digital zoom is carried out on a computer with photo-editing software, such as Photoshop. The CCD determines how many mega pixels a camera has e.g: a 12 mega pixel camera is able to take pictures in a variety of sizes, the maximum being 12 million pixels; this is big enough for a 4000 x 3000 picture to be taken. When a picture has a number of pixels, editing small parts of it and zooming it in is easier. With some images i had asked to edit i went out before starting the assignment and was asked to take a number of photos of college life that I could edit so that I was ready for editing when we started the assignment.

Scanner: scanners are the best way to put paper images into a computer. They work similar to photocopiers, with a bar that moves across the length of the scanner under the glass. The paper that is going to be copied is placed face down onto the glass window and a mechanism moves back and forth underneath the glass. Light bounces of the paper from a lamp and reflects into the lens. This makes the image into the CCD; this digitises the results via an analogue-to-digital converter. It the sends this information to the scanners hardware and then to the PC. The resolution of scanners has rapidly increased in the past few years and they are no longer a standalone piece as they can be integrated into printers. It is rare to find a scanner with less than 600 dpi. Even though you don’t need more than 300 dpi for scanning a photo. The most common dpi is 1200 x 2400 dpi, and the maximum resolution is 9600 dpi. I was asked to scan in an image onto Photoshop and edit it much like I had for the other images however this image i had not taken but still had to use techniques that i had learnt from editing the other images.
Resolution: Is the number of pixels on-screen, it is expressed in terms of the number of pixels on the horizontal and vertical axis. The higher the resolution on screen, the more pixels to create the image, the sharper and clear the image displayed is. When editing images one thing that i was asked to do was increase the resolution of an image to make it look sharper and better off to show for a college open day.
Storage: File Management: This involves the methods used to keep care of work saved to the hard drive or USB drive, including the following:
-File naming: This is naming a file to what it is, important to name it to what it is so its easier to find.
-Folder structure: This one of the most powerful tools that IT professionals can use to help organise all their work. As putting everything in a folder allows a certain structure to be created allowing you to know where everything is located. There are various ways to organise folders. The best one is the one that is more suited to the user.
-Moving files: this involves cutting it from a folder then pasting it into another folder. You might need to move files around when cleaning up your folder structures, so that the files are all in the correct locations and are easy to find.
-Deleting files: means removing them from the drive so they cannot be used again. so that you can remove files that you don't need, that are taking up space such as temp files.
