4 Pixilation is an effect caused by displaying a digital image or a section of a digital image at such a large size that individual pixels, small single-colored square display elements that compose the image, are visible to the eye.

5 Types of Digital Cameras Point and Shoot Cameras 8 x 10 prints 3 to 4 Megapixels Little Creative Control Prosumer Cameras 8 x 10 prints 5 to 6 Megapixels Advanced Features Professional Cameras DSLR (Digital Single Lens Reflex) 6 to 12 Megapixels Changeable Lenses

22 Image Compression Lossless Compression RAW or TIFF Lossy Compression JPEG

23 Least Compression (less distortion) Most Compression (more distortion)




27 Typical Picture-Taking Modes



30 Shutter Speed Fast Shutter Speed – reduces blurring effect of moving subjects Slow Shutter Speed – increases blurring effect of moving subjects


32 Aperture Depth of Field Small Aperture (large number) Large Aperture (Small number)






38 LCD Display Immediate Feed back Arm Shake Uses Power Can Be Misleading Hard to Use in Bright Light Viewfinder Conserves battery power Not all cameras have them Can’t take angled shots Suffer from Parallax Can be Blocked by extended lens

39 Composing A Picture 1. Rule of Thirds 2. The Golden Rule 3. Leading Lines 4. Contrast 5. Framing the Photograph Identify Point of Interest

40 Lake and Rock Take up 1/3 The dominant object is 1/3 from bottom/top/left or right Rule of Thirds

41 The most important part of the image is near the lower right corner of the picture (the lower right quarter) Golden Rule

42 Lines/Elements that lead the eye into the photo Leading Lines

43 Object and Background Contrast

44 Background is Framed by Foreground Object Framing the Photograph

45 Optical Zoom - Good Digital Zoom - Bad

46 Flash Options No Flash Forced Flash Fill Flash Red-eye Reduction Flash Slow-Sync Flash (Night Mode)

47 Depress button halfway and hold Some cameras give exposure info Some allow focus on multiple objects Shutter Button Activation

48 USB Cable (some cameras require specific software) Memory Card Reader Printers with built in card readers Downloading Images to Computer
