  1. Introduction toDigitalPhotography Key West Naval Air Station Earl D. Gates

  2. Overview • Quick overview of what this workshop is all about • Identifying the Hardware • Developing a digital image workflow • Photographic Techniques • Image Editing

  3. Hardware Terminology • Digital Camera (Digicam) • Megapixels • File Format • Batteries • Lens • Scanners • Flat Bed • Film

  4. Digital Imaging Workflow • Preparation • Shooting • Transferring • Organizing • Processing • Archiving • Outputting

  5. Photographic Techniques • Composition • People • Landscape • Pets

  6. Image Editing • Software • Tools • Special Effects

  7. Resources • Internet • Magazines • Books • Workshops

  8. Summary • Review topics • Identify level to achieve • What Next?

  9. Preparation • Select digicam and accessories • Check batteries • Clean the camera • Adjust controls • Extra memory cards • Field storage Back

  10. Shooting • Autofocus • White balance • Set other controls • Review images • Remove unwanted images Back Back

  11. Transferring • Decide on a transfer location • Memory card transfer • Cable transfer • Infrared transfer Back

  12. Organizing • Sort through images • Print contact sheets • Rank images in groups • Separate the keepers Back

  13. Processing • Working file format (TIFF) • Evaluate images • Make overall adjustments • Make local adjustments • Save as master • Sharpen image Back

  14. Archiving • Organize • Choose medium • Make multiple backups • Delete all unnecessary copies of image Back

  15. Outputting • Select output • File format • Email • Slide shows • Prints Back

  16. Composition • Learn to see • Rules of thirds • Viewfinder awareness • Simplicity Back

  17. People • Lens • Lighting • Posing • Props • Groups Back

  18. Landscapes • Lens • Lighting Back

  19. Pets • Lens • Red Eye Back

  20. Software • Photoshop • Photoshop Elements • Included with camera Back

  21. Tools • Opening, saving and deleting • Cropping • Adjusting brightness, contrast and color • Sharpening • Removal tools - redeye, dirt, scratch, noise Back

  22. Special Effects • Filters • Masks Back

  23. How Many Megapixels? Back

  24. File Format • Refers to the way the computer stores the data • More common formats include: • JPEG • EXIF • TIFF • RAW

  25. JPEG • Stands for Joint Photography Experts Group • Most widely used format • Biggest advantage - can compress image data • Do not edit JPEG images in photo-editing programs to minimize data loss

  26. EXIF • Stands for Exchange Image File Format • Used by many digicams • Is a variation of the JPEG format • Stores extra data as metadata with the image file • Metadata stores shutter speed, aperture, and other capture settings

  27. TIFF • Stands for Tagged Image File Format • Is the choice for bringing images into publishing programs • Does not compress as much as JPEG • Choose when picture quality is more important than file size

  28. RAW • Simply means raw • Used by high-resolution digicams • Does not include any in-camera processing features • Provides a truer version of the scene in front of the camera • Large file size Back

  29. Rechargeable Batteries Must Know Info

  30. Why Batteries? Batteries are the soul of photographic equipment

  31. Battery Types Rechargeable • Nickel-Cadmium (NiCd) • Nickel-Metal Hydride (NiMH) • LithiumIon (Li-ion)

  32. NiCd Batteries • Memory effect

  33. NiMH Batteries • More widespread

  34. Li-ion Batteries • Proprietary for specific cameras

  35. Milliampere hours (mAh) • Refers to how long the battery will last Back

  36. Its About The Speed Lenses

  37. Why does speed matter? The more light a lens gathers, the less time it needs to hold the shutter open for proper exposure

  38. Zoom Lens Maximum zoom is hard to hold camera steady for a sharp picture

  39. Shutter Speed Slowest shutter speed without a tripod is 1/focal length of lens (Based on 35mm equivalent)

  40. To Avoid The Shakes Image stabilization: Using gyro-sensors to detect shakes and compensate Allows image to be shot at slower shutter speed
