Photography made simple

  1. 1. Photography made simple By VidhyaShankar www.aquashankar.com
  2. 2. Topics • DSLR or Point & Shoot • Aperture • Depth of Field (DOF) • Shutter Speed • ISO • The X factor and EV • Lenses and Bodies • Composition and Tips
  3. 3. DSLR or Point & Shoot • Comparison between sensors Feature DSLR Point & Shoot Image Quality Very Good Good Versatility Excellent Average Sensor Very Good Almost on par with a DSLR Lenses Infinite Combos Only one Portability Painful Excellent Resale Value High Low P&S Sensor DSLR Sensor
  4. 4. Aperture • Lens Diaphram which regulates light • Larger aperture, lower the f-stop number • Larger aperture, lower depth of field • Larger aperture, more light
  5. 5. Depth of Field • The distance between the nearest and the furthest objects that give an image judged to be in focus in a camera. Courtesy: http://www.exposureguide.com/focusing-basics.htm

  8. 8. DOF - Examples
  9. 9. • Simple definition – “the amount of time the shutter is open” • Measured in seconds of fractions – 1/1000 is faster than 1/30 • Below 1/60, a tripod is good to have for image stabilization though one can take a photo on a body with Shake/Vibration Reduction even at 1/10s • Freezing a moment needs a high shutter speed • Motion needs a low shutter speed • Depends on focal length. Larger the focal length, higher the shutter speed necessary Shutter Speed
  10. 10. Shutter Speed - Examples 1/250s 1/60s
  11. 11. ISO • ISO is the International Organisation for Standardization. • Refers to the sensor’s sensitivity to light • Lower sensitivity means sharper images • Higher sensitivity is used when light is insufficient • Lower sensitivity – better images • Higher sensitivity – grainy images
  12. 12. ISO Examples
  13. 13. The X Factor • The magnification of X shown on Point & Shoot cameras is merely a multiplier of the lens focal length o Example, if the lens says 10X zoom and is a 28mm lens, then the maximum magnification is 28 x 10 = 280mm • DSLR lenses use absolute terms for magnification. The same lens above will be called 28-280mm o Example, a telephoto lens of 50-300 is actually a 6X zoom but has a higher magnification than the above lens.
  14. 14. EV Compensation • The EV compensation helps you override the camera setting to either lighten or darken your image • Use the EV compensation based on the subject being shot. 0 EV +1 EV -1 EV
  15. 15. Lenses • Kit Lens – 18-55 mm o Above average quality o Has quality cuts to save cost o Still better than point & shoot • Prime Lens – Single Focal Length o Better Construction o Greater aperture range • Medium Telephoto is 85 – 135mm • Telephoto is 135 – 300mm • Super Telephoto is above 300mm
  16. 16. Frame/Compose with care. Make sure the photo conveys what you want it to Composition Tips
  17. 17. Move in to capture the subject. This keeps the focus on your theme and eliminates unwanted anchors Next slide indicates this importance Composition Tips
  18. 18. Extract your theme from a photo Composition Tips
  19. 19. Look at the light. It makes all the difference The angle of light, time of the day, and clouds Make sure you do not shoot with the light behind the subject unless done deliberately Composition Tips
