Title: Troubleshooting


1
Troubleshooting
2
Problem People have white faces when I use
flash.
  • Solutions
  • Use the scenery mode on point and shoot cameras.
  • Use matrix-metering or face-recognition.
  • Use Forced Exposure Compensation (FEC) on SLRs.
  • Add more ambient light open windows, doors,
    switch on all lights.

3
Problem People have red eyes
  • Solutions
  • Dont use flash
  • Use off camera flash instead
  • Red-eye reduction pre-flash
  • Pre-flash sends out a burst of flashes before the
    picture is taken, which causes pupils to
    constrict and therefore reduces red-eye.
  • Let subject look at bright light source first.
  • Make subject look at camera, but not at lens.
  • Retouching.

4
Problem The flash causes reflections
  • Solutions
  • Take the photo at an oblique angle to the
    reflecting surface
  • Dont use flash
  • Get close to the glass
  • Get the light source out of family of angles
  • i.e. Outside of diagrams shaded area

5
Problem Other reflections cause trouble
  • Solutions
  • Put the lens against the glass
  • Move around to move reflective elements
  • Wear dark colours
  • Dim the lights on your side of the glass

6
Problem The light is too harsh outdoors
  • Solutions
  • Shoot in the morning or late afternoon
  • Shoot in the shadow
  • Use a diffuser
  • Use a reflector

7
Problem Sunny pictures are too bright or dark
  • Solutions
  • Point and Shoot switch to beach or snow modes.
  • SLR or bridge use exposure compensation
  • Use matrix metering.

8
The photographs are blurry
  • There are two different types of blur
  • Motion blur
  • Focus blur

9
Problem Motion blur
  • Solutions
  • Steady the camera (tripod, wall posture)
  • Use larger aperture for shorter exposure
  • i.e. f/2.8 instead of f/5.6 gives you three
    additional stops1/400 instead of 1/50
  • Shutter speed shorter than 1/focal length
  • If youre using 100mm as your focal length, your
    shutter speed should be shorter than 1/100
  • Use flash, increase ISO
  • Use image stabilization
  • Panning
  • Switch to Sports mode

10
Problem Focus blur
  • Solutions
  • Manual focus
  • Smaller aperture for more DOF
  • f/2.8 is very shallow f/32 focused on more.
  • SLRs need contrast to focus
  • PS confused by backlighting, smoke, snow,
    reflections
  • Dont move after focus is locked
  • DO move with MF when shooting macro
  • Respect minimal focal distance

11
Problem Buildings look like they are falling over
  • Solutions
  • Get higher (stand on a ladder, or another rooftop
    if its a really high building)
  • Get further away from your subject to reduce
    distance distortion

12
Problem My composition looks boring
  • Solution
  • Get an unusual point of view
  • Use the rule of thirds
  • Use the Golden Ratio (also known as Phi)see
    diagram

13
Problem My composition looks boring (continued)
  • Solutions
  • Try portrait instead of landscape
  • Use natural framing
  • Include lead-in lines
  • Tilt your camera
  • Move around your subject until you find a better
    angle

14
Problem The photo has too much noise
  • Solutions
  • Reduce ISO
  • Activate noise reduction in camera
  • Use noise reduction software
  • Use exposure stacking
  • Use a camera with a bigger sensor (full frame
    30-35x bigger than cameraphone)

15
Problem I cant zoom in enough
  • Solution
  • Get a tele lens
  • Zoom with your feet, i.e. Walk get closer to
    your subject
  • Crop your picture (on the computer)
  • DONT use digital zoom. EVER.
  • Basically, its just cropping within the camera,
    and reducing quality more than cropping with a
    computer.

16
Problem Not everyone fits into the photo
  • Solutions
  • Rearrange people into rows
  • Have the rows at different heights (stairs,
    chairs, kneeling)
  • Move to a higher point of view.

17
Problem My portraits look distorted
  • Solutions
  • Avoid wide angle for portraits (unless for
    special effect)
  • Anything above 50mm is ideal
  • Make the subject turn their head slightly
    sideways
  • Watch out for people that stand close to the edge
    in wide-angle groupshots

18
Problem My camera is slooooow
  • Solutions
  • Most cameras have a shutter lag, or delay
    between when the shutter button is pushed and
    when the photo actually takes
  • Use pre-focusing and pre-metering by
    half-pressing the shutter button
  • Use an SLR where possiblethe shutter lag is
    negligible.

19
Problem My batteries die too soon
  • Solutions
  • Protect them from the cold
  • Reduce screen brightness
  • Black out the display or use the viewfinder
  • Reduce review time.
