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

Image source: Screen Capture Screen capture acts as a camera that will take a picture of anything that is on the screen of your computer

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 “PrtSc” 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

Image source: 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)

Screen Capture In the previous slide we have three windows open Paint Microsoft Word Microsoft PowerPoint 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. PowerPoint

Internet How to save an image from the Web to your computer is covered in the presentation called downloading
