3. aaUEN Professional Development Why Go Digital? Resource from - http://www.shortcourses.com/http://www.shortcourses.com/ Saves you money by not buying rolls and rolls of film and paying for development. Saves you time you don't have to make two trips to the store to drop off and then pick up. Instantly see your pictures No more disappointments a day or two later when your film is developed.

4. aaUEN Professional Development View images before they are printed if you don't like what you see, edit them to perfection or delete them. Doesn't use the toxic chemicals that often end up flowing down the drain and into our streams, rivers, and lakes. No more waiting to finish a roll before having it processed. (Or wasting unexposed film when you can't wait.) Why Go Digital? Resource from - http://www.shortcourses.com/http://www.shortcourses.com/

10. aaUEN Professional Development Digital Image Basics Digital Photos/Bitmap Image digital images are made up of tiny squares called Pixels.

11. aaUEN Professional Development Digital Image Basics Cont. Quality and Size of Image Depends on the amount of pixels used to create the image. Referred to resolution  300 dpi same as 1inch = 300 pixels (when printing the image) When you reduce the size of an image you reduce the number of pixels. When you image is enlarged you computer adds pixels.  This can result in your picture looking pixilated.

12. aaUEN Professional Development Digital Image Basics Cont. Print v.s. Computer Screen If Printing the picture the more pixels the better.  Generally you want at between 150-300 dpi. If using the picture on a computer screen you want it to fit on the monitor without scrolling.  Common computer resolution is 800 pixels by 600 pixels.  If you image is bigger that that reduce the image size. Using your image on the web.  The less pixels the quicker the download.

13. aaUEN Professional Development 3 Steps to Digital Photography: Input Digital Camera, Scanning, Digital Video Image Processing Edit or manipulate the image with image editing software Output Display, distribute or storage of images. For example printing, email, insert in to documents, store for later. INPUTIMAGE PROCESSINGOUTPUT

14. aaUEN Professional Development How the Digital Camera Works: Image Sensor Instead of film the digital camera uses an image sensor, usually a CCD or Charge- Couple Device. The image sensor is made up of thousands to millions of pixels that record you image.

15. aaUEN Professional Development Exposure When you press the shutter button on the camera, light comes through the lens and each pixel records the brightness of light that falls on it. The more light that hits the pixel the brighter value the pixel records. Once the brightness value is recorded it is converted to a digital number and saved on the memory of the camera. The digital number allows the image to be reconstructed on screen or in a print. How the Digital Camera Works:

16. aaUEN Professional Development Photo Color The original image is only recorded as black and white (using brightness). To add color Red, Green, and Blue filters are placed over the image sensor to create a color photo. How the Digital Camera Works:

17. aaUEN Professional Development Types of Digital Cameras: Point and Shoot The least expensive digital cameras below $300. Fully automatic and little creative control-that's why they are called "point and shoot." Because of the low resolution of many of these cameras, printed output is limited to about 4 x 6 inches or so. The images are ideal for Web pages, e-mail attachments, and small reproduction sizes in newsletters and other documents.

18. aaUEN Professional Development Types of Digital Cameras: Multi-Megapixel Camera Quickly becoming the most common digital camera sold. Over a million pixels in their image sensors. Cost between $300-$1000 depending on the amount of mega pixels. Give some creative controls. Appeals to serious photographers who like to have creative control of their camera's settings and make prints up to about 8 x 10 in size.

19. aaUEN Professional Development Types of Digital Cameras: Professional Cameras 35mm or APS SLR cameras that have been adapted to digital photography Cost from $3000 to $20,000 and more. These cameras often use 3 image sensors, one for each color so they capture great color and resolution. At least 2-million pixels in their image sensors and usually many more. One huge advantage is that most of the features (and accessories designed for the film versions also work with the digital versions.

20. aaUEN Professional Development Camera Elements: Image Sensor - Resolution The number of pixel on an image sensor.  Lower resolutions such as 640 x 480 are perfect for web publishing, e-mail attachments, small prints, or images in documents and presentations.  Higher resolutions, over 1 million pixels, are best for printing photo-realistic enlargements larger than 5" x 7". Optical v.s. Interpolated Resolution  The optical resolution of a camera is the number of pixels on an image sensor that can be counted.  Interpolated resolution, adds pixels to the image to increase the total number of pixels.

21. aaUEN Professional Development Aspect Ratio Image sensors have different aspect ratios-the ratio of image height to width. The aspect ratio determines the shape and proportions of the photographs you create. To calculate the aspect ratio of any camera, divide the largest number in its resolution by the smallest number. Sensitivity An ISO is the speed, or sensitivity to light. The higher the number the "faster" or more sensitive the sensor is to light. Camera Elements:

22. aaUEN Professional Development Image Compression Image Compression makes large image files smaller, most cameras store images in a format called JPEG. This file format not only compresses images, it also allows you to specify how much they are compressed.  Less compression gives you better images so you can make larger prints, but you can't store as many images.  More compression lets you store more images and makes the images better for posting on a Web page or sending as an e-mail attachment. The only problem is that your prints won't be as good. Camera Elements:

23. aaUEN Professional Development Frame Rate There are two delays built into digital cameras that affect your ability to respond to fast action when taking pictures.  1 or 2 second refresh rate delay between pressing the shutter button and actually capturing the image. This occurs as the camera clears the image sensor, and set the correct controls.  The recycle time, occurs when the captured image is processed and stored. This delay can range from a few seconds to half a minute. Camera Elements:

24. aaUEN Professional Development Image Storage Fixed v.s. Removable Storage The two most common types of removable storage are Flash Memory Cards and Magnetic disks. The number of images that can be stored depends on the following:  Capacity of the storage devise  Resolution of the images taken  The amount an type of compression Camera Elements:
