Objective By the end of this you will be able to: • Capture images using a range of media (i. e. Cameras, scanners, screen capture, Internet) Image source: Microsoft Clipart Online
Screen Capture • Screen capture acts as a camera that will take a picture of anything that is on the screen of your computer Image source: http: //www. seoconsultants. com/windows/keyboard/
Screen Capture • To use Screen Capture you can press the button labelled “Print Screen” (as shown on the previous slide) • On laptops the button is labelled “Prt. Sc” • This button is usually located next to the “Pause Break” button
Screen Capture • When you press the “Print Screen” button it will take a picture of everything that is on you computer screen at that time and copy it to the clipboard • The clipboard is an invisible holding area for the copied image
Screen Capture • For the purpose of the demonstration we will use “Print Screen” now on this screen • Once the image has being captured you can then paste it into a word document or into Paint for further editing
Screen Capture • To paste it into any Microsoft application or Paint select the “Edit” menu • Then select “Paste” or press Ctrl +V
Screen Capture • By pressing “Alt” and “Print Screen” together you will get an image of the current selected window on your screen (this is the window that you are working on) Image source: http: //www. seoconsultants. com/windows/keyboard/
Screen Capture In the previous slide we have three windows open • Paint • Microsoft Word • Microsoft Power. Point As can be seen when we press “Print Screen” we get an image with all three windows but when “Alt” and “Print Screen” is pressed only one window is copied i. e. Power. Point
Internet • How to save an image from the Web to your computer is covered in the presentation called downloading
Internet • You don’t always need to save the image to your computer you can insert directly into an ICT package if desired
Internet How is this done? • When you find an image on a webpage that you want to insert into a Microsoft Word document for example right click on that image

Paste Special • When you have pasted the image into the document you can “Cut” (Ctrl +X) it again and use the “Paste Special” function again • This will now give you more formats to paste your image in as opposed to the initial formats when you used “Paste Special” once
