2. Today’s Agenda Digital Cameras… Things to Consider What Do Those Things Mean? Picture Taking Tips Play with the cameras Scavenger Hunt

3. Choosing a Digital Camera Who will use the camera? (child, adolescent, adult) What is your price range? What resolution do you require? What on-board (camera) image storage capacity do you require? Do you need manual override features, a fully automatic camera or a combination of these both? What is the battery capacity? Are battery chargers available for your camera? How sturdy is the camera? What features do you consider essential? (i.e.: self-timer, optical zoom, red-eye flash, movie mode) If you are doing your own print work, how fully featured is the editing software that comes with the camera? Is the camera compatible with your operating system? What is the warranty on the camera?

4. Digital Cameras Things to Consider… Resolution –Pixel – small squares –Megapixel – 1 million pixels –Pixelization

5. What is Resolution? Simply put, resolution is how you define the sharpness of your digital image. Resolution is often defined as how many pixels per inch (ppi) your image has in both its height and width. Resolution examples: Low EndMidrangeHigh End pixels at 640 X 480 or higherpixels at 1600 X 1200pixels at 2048 X 1536 or higher

6. What are pixels? Pixels are the building blocks of digital images. Every digital picture is made up of thousands of pixels. The number of pixels in each image affects the quality of the picture resolution. For example, a low-end camera might have 307,200 pixels in one picture. A high-end picture might have more than 5,000,000 pixels in a picture.

9. 640 x 480 640 pixels wide and 480 pixels high. This is a fairly low resolution that works well with email and Web postings. Pictures will print best if they are not bigger than 3” x 5” high. crisp 3" x 5" photo prints

10. 1600 x 1200 1600 pixels wide and 1200 pixels high. This can generally achieved with at least a 2 megapixel camera crisp 5" x 7" photo prints

11. 2048 x 1536 2048 pixels wide and 1536 pixels tall. This can generally be achieved with at least a 3 megapixel camera. crisp 8" x 10" photo prints

12. MegapixelsResolution Medium Print (150 DPI) Photographic Print (300DPI) 1.31280x10248.5 x 6.84.3 x 3.4 21600x120010.7 x 8.005.3 x 4.0 32048x153613.6 x 10.26.8 x 5.1 42272x170415.1 x 11.47.6 x 5.7 52560x192017.0 x 12.88.5 x 6.4 83264x244821.7 x 16.310.9 x 8.1

21. ViewFinders vs. Displays View Finder Low-end cameras rely on the traditional method of looking through a window to line up a picture subject. LCD Display Middle range and high-end cameras have a LCD (liquid crystal display) monitor for viewing pictures. Although very helpful in composing and viewing pictures, the LCD feature is a drain on batteries.

22. Night Scene – shutter stays open longer, tri-pod is suggested Mountain – for taking pictures of landscapes Lady – Head and shoulders portrait photo Action (Sport) – Fastest shutter speed for moving objects What Do Those Things Mean?

23. Macro Mode – Very close-up shots within inches of the subject; choose the tulip Movie Mode – Record movies; not sharp enough for DVD, good for email What Do Those Things Mean?

24. Flash Modes –Auto Flash – the camera decides when the flash is needed –Fill Flash – on all the time –Red-eye Reduction – flashes a light before the picture is taken; reduces pupil size –No Flash – is off

25. Picture Taking Tips 1.Take pictures at eye level when photographing a person 2. Use plain and simple backgrounds 3. Zoom in on the subject matter, you want it to fill the frame

26. Picture Taking Tips 4. Use a flash outside, especially if the sun is bright Without Flash With Flash

27. Picture Taking Tips 5. Rule of Thirds Move the focal point to where the lines intersect; much more interesting

31. Picture Taking Tips 6. Light source should not be behind the subject unless you want a silhouette effect

32. Picture Taking Tips 7. Lock your focus

33. File Formats File Format describes the particular computer code used to store your files. There are many different image file formats. The most common: JPEG – most common - compressed – Windows or Mac TIFF – not compressed – Windows or Mac – used for printing BMP – not compressed – large – used for Windows wallpaper GIF – Windows or Mac – only uses 256 colors – good for emails When attaching a picture file to an email, the two file formats that are used most frequently are JPEG and GIF. For example, you might receive a picture file attached to an email that looks like this …puppy.jpeg. Because the file format is JPEG, you will immediately know it is an image.

34. Downloading Images There are a number of different ways to transfer images from a digital camera to a computer. By far the most common method is to use a cable connection from the camera to the computer's USB port.

35. How Can You Integrate Digital Photography in Your Classroom? Acquire images Analyze images Create image-based works Communicate ideas and understanding

36. Sample Image-Based Works 1.Create a photo journal of field trips 2.Class newsletter illustrations 3.Photos for greeting cards 4.Photos of vocabulary items 5.Create a personal or classroom alphabet with pictures 6.Use pictures for concept illustration (art, math, science)

38. Top Ten Tips for Teachers and Digital Cameras 1.Take a class. Learn about digital cameras so that you're more comfortable with using one in your classroom. Digital images can be a catalyst to learning and to teaching! Students are visual and are motivated to write by what they see and can capture with a digital camera. 2.Set up rules. Establish clear camera handling procedures with your students to avoid unnecessary wear and tear -- a sturdy camera strap minimizes risk. Also, define when and where students can take photographs - and the subject matter. 3.Manage the images. Create and label folders on your computer for storage of images. Students may also store on alternative media such as CD-RW, floppies, or removable drives. 4.Practice builds confidence. Practice uploading, saving, and editing images. Be sure that your students do the same. Trial and error is the best teacher in photography. Keep in mind that photography is an art form, but it is also supposed to be fun! 5.Know your camera. An inexpensive, low-resolution digital camera generally gets better results with close-ups. Get down to the eye level of your subject. By APTE Professional Education Development Group

39. Top Ten Tips for Teachers and Digital Cameras 6.Steady and sturdy. Stand with your feet shoulder-width apart, with one foot slightly forward. Keep your elbows close to your body. 7.Lights, camera, action! Action photographs, rather than still or posed photographs, often produce a more natural look. 8.Get the latest. Check your camera manufacturer's web site for product updates, including free downloadable software enhancements. 9.Light and Dark. Avoid photographing windows, glass, or other shiny surfaces head-on. Keep the sun at your back. When your subject is backlit, the object being photographed often appears too dark to see. Avoid photographing dark subjects against dark backgrounds and light subjects against light backgrounds. Avoid taking pictures outside at noon - the lighting at noon tends to be flat and results in dull-looking photographs. 10.Be digitally safe. Before taking pictures of your students, be sure to read and follow your school's policies about appropriate use of student photos. By APTE Professional Education Development Group
