  1. 1. Digital Single-Lens Reflex cameras usually consist of: A camera body and One or more interchangeable lenses DSLRs ability to change lenses opens up a world of possibilities for photographers. DSLR cameras adapt to different situations dues to a large range of other accessories (flashes, filters etc.) Why Do I Want A DSLR?
  2. 2. Typically an upgrade customer who: Wants a camera that brings the action closer Wants a camera without shutter delay Wants interchangeable lenses Wants to add accessories Wants a camera that takes better pictures than his/her last one Who Is an SLR Customer?
  3. 3. Absolutely Not! Most people who purchase an SLR aren't experts. They just want to have great photos Digital SLRs offer easy automatic shooting. SLRs also have full manual functionality This lets you be creative with picture taking Do You Have to Be An Expert To Use an DSLR? Photo by: Gabe Vasquez
  4. 4. Absolutely! They permit you to learn as you go. From automatic / Digital SLRs offer easy automatic shooting. SLRs also have full manual functionality This lets you be creative with picture taking You just try out an exposure setting, check the results, delete the shots that didn't work, and try again. Are DSLR Cameras Affordable?
  5. 5. They deliver more precise, dynamic, and vivid photos! Larger sensor size, (captures more info). More extensive manual controls. (Compared to point-and-shoot cameras). Faster internal processing for greater response time So Why Do Customers Use Digital SLRs? Photo by: Gabe Vasquez
  6. 6. The cameras viewfinder uses a 45 angled mirror The reflection of the image reflection lets you see and compose your subject through and is why it is called "single-lens reflex The mirror lifts up and out of sight briefly when you press the shutter button This allows the image sensor to capture the photo. The DSLR Mirror
  7. 7. Kits include both camera body and a lens (or two) to get you started. The lenses included with most kits make a good basic choice for all-around photography. More experienced photographers often buy just the body, then add specialized lenses Example: Long-range telephoto Wide-angle, or Close-up lens Kit Versus Body Only
  8. 8. LCD Viewscreen Most cameras' LCDs measure between 1.8" and 3.5" diagonally, Screen resolutions are between 100,000 and 240,000 pixels. The higher the LCD's resolution, the clearer your view will be of images and camera menus. LCD Image Screen
  9. 9. Sensor Size Larger sensors can capture tiny highlights or shadow details better than smaller sensors with the same megapixel count. What Are Some Features? Megapixel Approximately 1 million pixels and refers to the number of pixels in it that make up the image sensor that produces the photo. The more megapixels a camera has the better the enlargement is without losing detail.
  10. 10. The number of pixels used to capture an image. Resolution ranges from low (640 x 480) to high (3456 x 2592 and up). High resolution makes for sharper pictures; however, high-resolution photos take up more memory than lower-res photos. The higher its maximum resolution, the better its potential picture quality. What Is Resolution?
  11. 11. Histogram A simple display graph of brightness and darkness values as an objective view of exposure of a photograph. Speaking of Image Resolution Darkness Brightness
  12. 12. How fast a camera's shutter exposes the image sensor to light. A shutter speed of 1/60 means that the sensor is exposed to light for 1/60th of a second. Faster shutter speeds are good for "freezing fast-moving action; Slow ones allow you to intentionally blur the movement of your subject to emphasize motion. Shutter Speed
  13. 13. Aperture affects the exposure and depth of field (whats in or out of focus). A large aperture (f/1.4, f/2.8 etc.) lets in more light to the camera shutter for an exposure, A small aperture (f/11, f/16, f/22 etc.) has a smaller opening in the lens diaphragm to let in LESS light for a given exposure. What About Aperture
  14. 14. DSLRs offer a wide array of ISO settings and flexibility when shooting in different conditions. Changing your ISO setting means adjusting your camera's sensitivity to light. The lower the ISO number, the less sensitive it is to the light. A higher ISO number increases the sensitivity of your camera to light. Lower number = Lower sensitivity = finer quality photos. ISO Range (International Standards Organization)
  15. 15. Electronic adjustment of light levels to remove unrealistic color tones or hues. All digital cameras offer automatic white balance, and most feature additional preset levels or even custom manual settings. Used so that objects that appear white in person are rendered white in your photos. White Balance Without With
  16. 16. Counteracts the effects of camera shake so you can take sharper pictures in low-light settings and at slower shutter speeds. Comes in two different ways: As part of an IS lens attached to the camera Built into the camera body itself (Called Vibration Reduction by Nikon and SteadyShot by Sony) Image Stabilization
  17. 17. Allows you to press and hold the camera's shutter button to capture a series of shots in rapid succession. The images taken are temporarily stored in the cam's buffer memory and then written to the memory card. Continuous Shooting Mode (Burst) Great for sports or fast-moving subjects (sports, cars & kids)
  18. 18. Portrait &Telephoto Lenses A telephoto lens makes it possible to capture crisp, close-up shots of far-away subjects. Wide Angle Lenses A wide-angle lens can capture an extra-wide view of the scene. A Word About Lenses
  19. 19. Identify your needs and what fits your lifestyle before purchasing a DSLR. What kind of photos do you take Portraits, Landscapes, Kids, Sports Where will you be using it most? Indoor or Outdoor shots? Family Events/Portraits? Landscape/Nature? Summary Photos by: Gabe Vasquez
