Mastering Digital Image Capture: Essential Skills for Effective Classroom Communication

This session focuses on equipping educators and students with the necessary knowledge and skills to capture high-quality still images using digital cameras and scanners. It emphasizes the importance of selecting appropriate files and formats to enhance communication in Year 7 to 9. Participants will explore classroom management issues related to image capture and learn how to refine presentations by integrating still/moving images and sound. Additionally, the session delves into technical considerations that affect electronic communications, focusing on making information sharing efficient and purposeful.

Presentation Transcript

  1. Communication: text and graphics Session 3 Capturing images fit for purpose

  2. Objectives • To provide the knowledge, skills and understanding needed to capture still images, using digital cameras and scanners, taking account of fitness for purpose • To consider the classroom management issues associated with capturing images • To review existing practice

  3. Exchanging and sharing information (Year 7) Refining and presenting information • Use ICT to draft and refine a presentation, including: capturing still and moving images and sound (e.g. using a scanner, digital camera, microphone)

  4. Manipulating images for a purpose

  5. Exchanging and sharing information (Year 8 and Year 9) Communicating • Year 8: Understand some of the technical issues involved in efficient electronic communications (e.g. size and type of file) • Year 9: Apply knowledge of the technical issues involved to communicate information efficiently (e.g. choose suitable file types to speed up transfer)

  6. Why reduce file size? • To fit the image onto a floppy disc • To email the image • To save disc space on the network • To enable a web page containing the image to load more quickly • To enable a computer with limited memory to manipulate the image more quickly

  7. Appropriate bitmapped file formats

  8. bmp: 196K gif: 11K jpg low compression: 13K jpg high compression: 5K

  9. Selecting file formats for a purpose Exchanging and sharing information (Year 7) Refining and presenting information • Use ICT to draft and refine a presentation, including: capturing still and moving images and sound (e.g. using a scanner, digital camera, microphone)

  10. Comparison of vector and bitmapped images

  15. Vector images • Many formats • WMF • DXF

  16. Objective • To provide the knowledge, skills and understanding needed to capture still images, using digital cameras and scanners, taking account of fitness for purpose

  17. Exchanging and sharing information (Year 7) Refining and presenting information • Use ICT to draft and refine a presentation, including: capturing still and moving images and sound (e.g. using a scanner, digital camera, microphone)

  18. Exchanging and sharing information (Year 8 and Year 9) Communicating • Year 8: Understand some of the technical issues involved in efficient electronic communications (e.g. size and type of file) • Year 9: Apply knowledge of the technical issues involved to communicate information efficiently (e.g. choose suitable file types to speed up transfer)

  19. Planning for teaching the objectives • Have my pupils used a digital camera before? • How many of my pupils have used a scanner before? • How will I arrange for pupils to take photographs or scan them in? • How will I ensure that all pupils have an opportunity to use cameras and scanners? • How much technical information do pupils need to know to complete the tasks successfully? • What will I need to prepare to enable this to run smoothly in my classroom?

  20. Objectives To provide the knowledge, skills and understanding needed to use digital cameras and scanners to capture still images, taking account of fitness for purpose To consider the classroom management issues associated with capturing images To review existing practice
