Exposure Triangle

  • ISO: double ISO = double brightness, but also double noise. Stay lowest possible
  • Aperture: f/2.8 = shallow depth of field (blurry background), f/11 = everything sharp
  • Shutter: 1/focal length minimum for handheld — 50mm lens needs 1/50s or faster
  • Expose for highlights — blown highlights unrecoverable, shadows can be lifted in post

Focus Fundamentals

  • Focus on eyes for portraits — always the nearest eye
  • Back-button focus separates focus from shutter — press once to lock, recompose freely
  • Single-point AF for precision, tracking AF for movement
  • Hyperfocal distance for landscapes: focus 1/3 into scene, everything sharp at f/8-11
  • When in doubt, stop down — f/8 is sharper than wide open for most lenses

Composition Beyond Rule of Thirds

  • Leading lines pull eyes into frame — roads, fences, rivers toward subject
  • Frame within frame: doorways, windows, arches add depth
  • Negative space: empty area emphasizes subject — don't fill every corner
  • Odd numbers: 3 or 5 subjects more pleasing than 2 or 4
  • Break rules intentionally: centered subject with symmetry works

Natural Light

  • Golden hour: 1 hour after sunrise, 1 hour before sunset — warm, soft, directional
  • Blue hour: 20-30 minutes after sunset — even, moody, no harsh shadows
  • Overcast is giant softbox — ideal for portraits, no squinting
  • Midday sun: use as backlight or find open shade — avoid direct overhead
  • Window light: subject facing window, not camera — soft directional light

Flash Basics

  • Bounce off ceiling/wall — direct flash is harsh and flat
  • Flash exposure compensation: start at -1 to -2 stops — blend with ambient
  • High-speed sync for daylight fill — allows wide aperture outdoors
  • Off-camera flash: 45 degrees from subject, elevated — creates dimension
  • Catch light in eyes: small light source close beats large source far

Common Mistakes

  • Horizon not level — first thing viewers notice is wrong
  • Cutting at joints: ankles, wrists, knees — crop mid-limb or full body
  • Busy backgrounds: poles from heads, distracting elements
  • Chimping constantly — looking at screen after every shot instead of moments
  • Not checking histogram — LCD brightness deceives, histogram doesn't lie

Camera Settings by Genre

Portraits:

  • Aperture priority, f/1.8-2.8
  • Single-point AF on eye
  • +1/3 exposure for skin brightness

Landscapes:

  • Aperture priority, f/8-11
  • Tripod, mirror lock, remote/timer
  • Bracket exposures for HDR

Sports/Action:

  • Shutter priority, 1/500s minimum
  • Continuous AF tracking
  • Burst mode, anticipate peak action

Street:

  • Aperture priority, f/5.6-8
  • Zone focus preset at 3m
  • Shoot from hip if needed

RAW vs JPEG

  • Shoot RAW for editing flexibility — recovers 2-3 stops of exposure
  • JPEG for volume without editing — events with hundreds of shots
  • RAW + JPEG: preview immediately, edit RAW later
  • RAW files need processing — they look flat by design, not a problem

Editing Workflow

  1. Cull ruthlessly: delete obvious failures first
  2. Global adjustments: exposure, white balance, contrast
  3. Local adjustments: dodge/burn, graduated filters
  4. Color grading: consistent look across set
  5. Export: sRGB for web, AdobeRGB for print
  • Edit on calibrated monitor — laptop screens lie about color
  • Sharpening last, after resize — oversharpening destroys detail
  • Less is more: if you notice the edit, you went too far

Gear Reality

  • Best camera is the one you have — phone beats DSLR at home
  • Lenses matter more than bodies — invest in glass first
  • 50mm f/1.8 is best first prime — cheap, sharp, teaches composition
  • Tripod: don't cheap out — flimsy tripod is worse than none
  • One good light > three bad ones — start with single source

File Management

  • Backup same day: 3-2-1 rule (3 copies, 2 media types, 1 offsite)
  • Folder structure: YYYY/YYYY-MM-DD_EventName
  • Rename files: YYYYMMDD_ProjectName_0001.ext
  • Keywords and ratings during import — not later when you forget context
  • Archive RAW files forever, even rejected ones — storage is cheap, moments aren't
