File Types
• GIF - raster-based color graphics file format, often used on the World Wide Web to store graphics. This is the type best used for cartoon-like images. • JPEG - A graphic format that allows images to be viewed on the Web. It allows compression of memory, using less space and facilitating faster load time on a Web page. This is the type best used for photographs.
Web images
• GIF Images- Graphics Interchange Format (GIF) images are the most common type of image found on the Web. GIF images are limited to 256 colors, which is the same number of colors most computer monitors can display. • JPEG Images- Joint Photographic Experts Group (JPEG) images are commonly found on the Web. JPEG images can have millions of colors and are often used for photographs and very complex images. • PNG Images- Portable Network Graphics (PNG) images are a newer type of image specifically designed for use on the Web. PNG images can have millions of colors will eventually replace GIF images.
What is a Mega Pixel?
• A unit equal to one million pixels. • The higher the resolution, the more pixels in an image and therefore the greater the image quality. • An image file that is 1 megapixel (MP) can make a photo realistic print of 5 x 7 inches; a 2 MP file can make an 8 x 10-inch print; a 3 MP file can make an 11 x 14-inch print.
Memory Cards
• Memory cards store the actual data files of your photos • The bigger the memory card the more photos you can take • The faster the memory card the faster you can take pictures • The memory card type is not as important as the two above features
• Both
• Adobe Photoshop • Macromedia Fireworks

What is a Mega Pixel?
• What is a Pixel first…

What do MP & Resolution have to do with me?
• To find the largest photo quality image you can print, simply divide each dimension by ppi (I.e. 300 or 72)
Up-close & Personal
• Embracing your inner zoom & the MACRO feature on your camera • The macro mode button, when pressed, switches the camera into a special close focus mode and allows the photographer to shoot less than 10cm from the picture subject.
Action Shots
• Keep taking pictures - you have space!
To Flash or not to Flash
• Use natural light whenever possible • Use flash sparingly • If unsure, take one with and one without and decide later!
Macro
Go Vertical!
• The camera is not locked in a horizontal position! • Vertical pictures suit some subjects better - and are much easier to add in PowerPoints!
Rule of Thirds
Imaginary lines are drawn dividing the image into thirds both horizontally and vertically. You place important elements of your composition where these lines intersect.

Resolution
• The number of pixels per square inch on a computer-generated display; the greater the resolution, the better the picture. • For display on a screen, 72 pixels per inch both vertically and horizontally is the maximum. • For print work, a higher number will give better results, such as 300 dots per inch. • With higher resolution, more memory space will be used for the image.
