photojournalism field guide
Built in memory of Dith Pran
Photojournalist · Survivor · Witness · 1942–2008
Photographer's Rights (USA)
You may photograph anything visible from a public place — streets, buildings, people, police activity — without permission.
Police cannot legally delete your images or demand you stop shooting in a public space.
Private property owners may ask you to leave. You must comply, but they cannot seize your camera or memory cards.
Editorial use of images taken in public does not require model releases in most jurisdictions.
Commercial use of identifiable people requires a signed model release.
Always check local and international laws when working outside the USA — rights vary dramatically.
Ethics in the Field
Do not alter the content of news photographs. Cropping and tonal adjustment are acceptable. Adding or removing elements is not.
Caption accurately. Who, what, where, when. Never assume — confirm.
Subjects in crisis deserve dignity. Ask yourself: would I want this image published of me at my worst moment?
Bearing witness is a responsibility. Dith Pran stayed behind so the world would know. That choice defines what photojournalism is.
If you witness something that requires immediate human intervention, intervene first. Photograph second.
Field Gear Checklist
Safety in the Field
Always tell someone where you are going and when to expect you back. Check in regularly.
Know your exits before you need them. In any crowd, location, or building — identify two ways out.
Press credentials help but do not protect you. Wear them clearly in conflict zones. Remove them in situations where they make you a target.
Back up your memory cards at every opportunity. The image that matters most is the one you almost lost.
Know the signs of secondary trauma. Photojournalism takes a toll. Talk to someone.
Manual — White Balance & Color Temperature
What white balance does: Every light source casts a different color. Your eye corrects automatically. Your camera does not — unless you tell it to. White balance tells the camera what "white" looks like under your current light so all other colors fall correctly around it.
Kelvin scale — color temperature reference:
1,000–2,000K — Candlelight. Deep orange.
2,500–3,200K — Tungsten / incandescent bulb. Warm orange-yellow.
3,200–4,000K — Halogen. Slightly cooler warm white.
4,000–5,000K — Fluorescent. Neutral to slightly green-white.
5,000–5,500K — Daylight / electronic flash. True neutral white.
5,500–6,500K — Overcast sky. Cool blue-white.
6,500–8,000K — Open shade. Noticeably blue.
8,000–10,000K — Deep shade / blue sky. Very blue.
Camera presets and when to use them:
Auto (AWB) — Reliable in mixed or changing light. Can shift between frames. Not ideal for consistency across a series.
Daylight / Sunny — 5,200K. Use outdoors in direct sun.
Cloudy — 6,000K. Adds warmth to compensate for cool overcast light.
Shade — 7,000K. Corrects deep blue cast in shaded areas.
Tungsten — 3,200K. Use under incandescent bulbs to remove orange cast.
Fluorescent — 4,000K. Use under office or studio fluorescent lighting.
Flash — 5,500K. Matched to most electronic flash output.
Custom / Kelvin — Set a precise value. Best for controlled studio work.
Practical rules:
Shoot RAW and you can correct white balance in post with zero quality loss. It is a metadata instruction, not a pixel change.
Shoot JPEG and white balance is baked in. Get it right in camera.
Mixed light sources (tungsten ceiling + window light) cannot be fully corrected with a single WB setting. Choose the dominant source and correct the rest in post, or use gels on your lights to match sources.
When in doubt, shoot slightly warm. Cold images feel clinical. Warm images feel human.
Color casts to recognize:
Orange cast — too warm / WB set too high in Kelvin. Lower your Kelvin value or switch from Tungsten preset in daylight.
Blue cast — too cool / WB set too low. Raise Kelvin or use Cloudy/Shade preset.
Green cast — fluorescent contamination. Switch to Fluorescent preset or correct with magenta tint adjustment.
Magenta cast — over-corrected fluorescent. Reduce magenta in tint control.
Manual — Post-Processing & the Edit
RAW vs JPEG — the fundamental choice:
RAW — The full unprocessed sensor data. Every bit of information the camera captured. No in-camera sharpening, no compression, no baked-in processing. Larger files. Requires post-processing software (Lightroom, Capture One, Darktable — free). Maximum editing latitude. The professional standard.
JPEG — Processed and compressed in-camera. Smaller files. Ready to use immediately. White balance, contrast, and sharpening are baked in and partially destructive to edit. Fine for social media and quick turnaround. Not for anything you intend to print large or edit heavily.
RAW+JPEG — Shoot both simultaneously. RAW for editing. JPEG for immediate sharing. Uses more card space but gives you both options.
Reading the histogram:
The histogram is a graph of tonal values in your image — left is black (shadows), right is white (highlights), middle is midtones. Height at any point shows how many pixels exist at that brightness.
Clipping left (shadows) — a spike hard against the left wall means pure black with no detail. Lost shadow information.
Clipping right (highlights) — a spike hard against the right wall means pure white with no detail. Blown highlights. Cannot be recovered.
Expose to the right (ETTR) — push your exposure as far right as possible without clipping highlights. RAW files hold far more recoverable detail in shadows than highlights. Underexposed RAW files produce noise when lifted. Overexposed highlights are gone forever.
A good histogram has no hard clipping on either wall — unless the scene genuinely contains pure black or pure white.
The basic tonal edit — in order:
1. White balance first — correct the color cast before anything else.
2. Exposure — overall brightness. Raise or lower the midtones.
3. Highlights — recover blown areas by pulling down.
4. Shadows — open up dark areas by lifting.
5. Whites — set the brightest point just below clipping.
6. Blacks — set the darkest point. Adds contrast and grounding.
7. Contrast — overall tonal separation. Use sparingly after the above.
8. Clarity / texture — midtone contrast and local detail. Not sharpness.
9. Vibrance / saturation — color intensity. Vibrance protects skin tones. Saturation affects all colors equally.
10. Sharpening and noise reduction last — always.
Sharpening and noise:
Sharpening is always the last step. It enhances whatever is already in the image — including noise. Sharpen after noise reduction.
Noise reduction softens detail. Apply the minimum needed. Over-processed images look plastic.
High ISO noise is normal. It is not a failure. It is a record of available light. Many of the most important photographs ever taken are grainy.
Export settings reference:
Web / social media — JPEG, sRGB color space, 72–96 PPI, longest edge 2048–3000px, quality 80–90%.
Print (home / lab) — JPEG or TIFF, sRGB for most labs / Adobe RGB if your lab supports it, 300 PPI at final print size.
Large format print — TIFF preferred, Adobe RGB, 300 PPI minimum at output size. Check with your print lab.
Client delivery — JPEG, sRGB, full resolution, quality 95–100%.
Archive / master — Full resolution RAW preserved. Never delete originals.
The ethics of editing — photojournalism standard:
Tonal adjustments, cropping, and dust removal are acceptable.
Removing, adding, or moving any element in a news photograph is fabrication.
AI-generated or AI-altered content must be disclosed and is not acceptable in editorial contexts.
The photograph is a record. Treat it as one.
Manual — Camera Systems & Sensor Formats
Sensor format explained:
The sensor is the digital equivalent of film. Its physical size determines how much light it captures, how lenses behave on it, and how shallow your depth of field can be. Larger sensor = more light = less noise = shallower DOF potential at equivalent apertures.
Full Frame (35mm equivalent) — crop factor 1.0x:
Sensor size: 36mm × 24mm. The gold standard. A 50mm lens behaves like a 50mm lens. Maximum low-light performance. Shallowest depth of field. Largest, heaviest bodies. Most expensive.
Common systems: Canon EOS R, Nikon Z, Sony A7, Leica M.
APS-C (Crop sensor) — crop factor 1.5x–1.6x:
Sensor size: approx 24mm × 16mm. Multiply your lens focal length by the crop factor to get the full-frame equivalent. A 35mm lens on APS-C behaves like a 52mm on full frame. Smaller, lighter, less expensive. Excellent image quality in modern sensors. The working photographer's most common format.
Common systems: Fujifilm X, Sony A6000 series, Canon EOS M/R50, Nikon Z30/50.
Micro Four Thirds (MFT) — crop factor 2.0x:
Sensor size: 17.3mm × 13mm. Double the crop factor. A 25mm lens is equivalent to 50mm full frame. Very compact systems. Excellent video. More depth of field at equivalent apertures — an advantage for video, a limitation for shallow portrait work.
Common systems: Olympus OM / OM System, Panasonic Lumix G.
Medium Format — crop factor 0.64x–0.79x:
Sensor larger than 35mm. Extraordinary dynamic range and tonal graduation. The tool of studio photographers, landscape specialists, and high-end commercial work. Very expensive. Not a field camera for most assignments.
Common systems: Hasselblad X, Fujifilm GFX, Phase One.
Smartphone cameras:
Tiny sensors (typically 1/1.7" to 1/1.28") with computational photography compensating for physical limitations. Excellent in good light. Noise and dynamic range limitations in low light that no software fully overcomes. The best camera is the one you have. Every important photograph taken on a phone is proof that the sensor is not the story — the eye is.
Megapixels — the truth:
24 megapixels is sufficient for any print up to approximately 20×30 inches at 300 PPI.
45–60 megapixels is for large format printing, heavy cropping, or commercial billboard work.
More megapixels means larger files, slower cards, more storage, and more processing time. It does not mean better photographs.
The single biggest factor in image quality is not megapixels — it is light.
Memory cards — what matters:
Speed class affects write speed — important for burst shooting and video. Look for V30 minimum for stills, V60 or V90 for RAW burst or 4K video.
Capacity: 64GB–128GB is a practical working size. Carry multiples rather than one large card — a failed 256GB card loses everything.
Brand: SanDisk, Lexar, Sony, ProGrade. Avoid unbranded cards. A card failure in the field is irreversible.
Never format a card until images are backed up in two locations.
Free tools and resources — what the pros use:
Darktable — Free, open source RAW processor. Full professional feature set. Cross-platform.
RawTherapee — Free RAW editor. Exceptional tonal control. Steeper learning curve.
GIMP — Free image editor. Not optimized for RAW but powerful for post-processing and retouching.
PhotoPills — Paid but affordable. Sun, moon, Milky Way planning. Essential for landscape and astro photographers.
The Photographer's Ephemeris — Sun and moon position planning. Web version free.
Lightroom (Adobe) — Industry standard. Subscription. The most widely used professional workflow tool.
Capture One — Professional alternative to Lightroom. Excellent color science. Subscription or perpetual license.

ND (Neutral Density) filters reduce light entering the lens without affecting color. Each stop of ND requires doubling the shutter speed. A 10-stop ND turns 1/1000s into 1 second.
Select base shutter speed and ND strength above.
FILTER REFERENCE NEUTRAL DENSITY (ND) Reduces light without affecting color. Common uses: long exposures in bright light, open aperture in sun, smooth water and clouds, video at 180° shutter rule. VARIABLE ND Adjustable ND in a single filter. Convenient but can introduce cross-polarization (X pattern) at extreme settings. Use quality brands (Tiffen, B+W, Nisi, Breakthrough). CIRCULAR POLARIZER (CPL) Reduces reflections on water, glass, and foliage. Deepens blue sky — maximum effect at 90° to the sun. Adds approximately 1.5–2 stops of light reduction. Rotate the front element until reflections disappear. Does not work on metallic reflections. UV / HAZE FILTER Primarily used as lens protection. Modern coated lenses have minimal UV sensitivity — image quality benefit is negligible. A quality UV filter has no image impact. A cheap UV filter introduces flare, reduces contrast, and costs you more than it protects. GRADUATED ND (GND) Darker at top, clear at bottom. Used to balance bright sky with darker foreground in landscape. Hard GND — sharp transition. Use when horizon is flat (seascape). Soft GND — graduated transition. Use when horizon has irregular elements. Reverse GND — darkest in the centre. For sunrise/sunset where brightest point is on the horizon. COLOUR FILTERS (film era / creative use) Still used in film photography and creative digital work. Red filter — darkens sky dramatically, lightens warm tones, high contrast landscapes. Yellow filter — moderate sky darkening, classic portrait and landscape rendering. Orange — between red and yellow. Standard landscape filter. Green — lightens foliage, useful for natural scenes. 81A/81B warming filter — adds warmth without color cast in digital (often replaced by WB adjustment).

Color Theory
Skin Tones
Color Grading
COLOR RELATIONSHIPS FOR PHOTOGRAPHERS COMPLEMENTARY COLORS — Maximum contrast and vibration. Pairs that sit opposite on the color wheel: Red / Cyan Orange / Blue — The classic cinematic pairing. Warm skin against cool sky or shadow. Yellow / Purple Green / Magenta ANALOGOUS COLORS — Harmony and cohesion. Colors adjacent on the wheel — they feel unified. Warm analogous: Red, Orange, Yellow — sunset, autumn, warmth Cool analogous: Blue, Cyan, Green — underwater, forest, winter TRIADIC — Balanced vibrancy. Three colors evenly spaced. Energetic but controlled. Primary: Red, Yellow, Blue Secondary: Orange, Green, Purple SPLIT COMPLEMENTARY — Softer than full complementary. One color plus the two colors on either side of its complement. Less tension than true complementary — more sophisticated. THE ORANGE AND TEAL LOOK The most prevalent cinematic grade of the past 15 years. Works because human skin contains orange/warm tones — the teal shadows complement and separate from skin beautifully. Too much of it reads as commercial. Use with restraint. THE GOLDEN RATIO OF COLOR IN COMPOSITION 60% — dominant color (background, environment) 30% — secondary color (clothing, mid elements) 10% — accent color (small detail, point of interest) This proportion creates visual hierarchy without competition.
Backup

Card Tracker
THE 3-2-1 BACKUP RULE 3 COPIES of every important file 2 DIFFERENT STORAGE TYPES (e.g. internal drive + external drive, or SSD + NAS) 1 OFFSITE COPY (cloud storage, drive at another location, or upload to client) THE PROFESSIONAL WORKFLOW On location: 1. Shoot to primary card. 2. If camera has dual card slots: write simultaneously to backup card. 3. Back in hotel: copy primary card to laptop AND external drive before sleeping. 4. Never format a card until the images are on at least two drives. After the shoot: 5. Ingest to primary working drive. 6. Copy immediately to backup drive. 7. Upload selects or full shoot to cloud (Backblaze, Google Drive, Dropbox). 8. Keep the original cards until delivery is confirmed. THE CARDINAL RULE Never format a card until the images are confirmed in at least two locations. "I'll do it later" is how careers end. STORAGE MEDIA COMPARISON SSD — Fast. Reliable. No moving parts. More expensive per GB. Lifespan: 5–10 years in active use. Degrades without power over time. HDD — Slower. Moving parts. Fails with drops. Cheaper per GB. Lifespan: 3–5 years in active use. Mechanical failure is common. RAID — Multiple drives. Redundancy built in. Not a backup — a convenience. RAID protects against drive failure. Not against theft, fire, flood, or human error. Cloud — Offsite by definition. Dependent on internet and subscription. The best offsite backup available to most photographers. LTO Tape — Long-term archival standard at the highest professional level. Expensive setup. 30+ year archival lifespan. Used by studios and archives. RECOMMENDED MINIMUM SETUP Working drive (SSD or HDD) — active project files Backup drive (external HDD) — mirror of working drive, updated daily Cloud storage — offsite, updated after each shoot Original cards kept until delivery confirmed DO NOT DO THIS Format cards immediately after transfer to one device. Store all drives in the same physical location. Rely on cloud as your only backup without a local copy. Delete RAW files after delivering JPEGs.

GOLDEN HOUR — WHAT IT IS AND HOW TO USE IT Golden hour is the period after sunrise and before sunset when the sun is low on the horizon. Light is warm, soft, and directional — it wraps around subjects, creates long shadows, and adds dimension that midday light destroys. SUNRISE GOLDEN HOUR Arrives without warning. The light changes fast — you have minutes, not hours. Scout the night before. Know exactly where you will stand and what you will point at. Set up before civil twilight ends. Wait. SUNSET GOLDEN HOUR More predictable. Watch the light direction as afternoon progresses. Position yourself so the light falls where you want it. The best light often comes in the last 10 minutes before the sun drops below the horizon. BLUE HOUR Before sunrise and after sunset. The sky turns a deep, even blue — no harsh shadows, balanced ambient light. Ideal for architectural photography, cityscapes, and any scene where you want the sky to retain detail alongside artificial light. Lasts 20–30 minutes depending on season and latitude. CIVIL TWILIGHT The period when the sun is between 0° and 6° below the horizon. Enough light to see without artificial sources. For photographers: the transition zone between blue hour and true darkness. Some of the most dramatic sky conditions occur here. PRACTICAL NOTES The closer to the equator, the shorter the golden hour. Near the poles in summer, golden hour can last hours. In Florida (Pete's location) golden hour is brief — typically 20–30 minutes. Plan accordingly. Overcast days eliminate golden hour quality but can create beautiful, even diffused light all day. Do not cancel a shoot because it is cloudy.
Moon
moon phase · moonrise · moonset · illumination · astro planning
Moon phase and illumination calculated precisely for any date. For moonrise and moonset times, the tool uses astronomical algorithms accurate to within minutes. No API required — all math runs locally.
Select a date to calculate moon data.
MOON PHASES FOR PHOTOGRAPHERS NEW MOON — 0% illuminated The sky is darkest. No moonlight to compete with stars. Best for: Milky Way photography, deep sky, maximum star visibility. The galactic core is visible from dark sky locations. WAXING CRESCENT — 1–49% illuminated, setting after sunset A thin crescent low in the west after sunset. Good for landscape compositions with a crescent moon. Sets early — leaves the night dark for astro work. FIRST QUARTER — 50% illuminated, setting around midnight Half moon. Sets around midnight — gives you a dark sky for the second half of the night. Good compromise for photographers who want some moonlight AND dark sky time. WAXING GIBBOUS — 50–99%, setting after midnight Moon is bright enough to illuminate landscapes. Good for moonlit landscape work but washes out stars. FULL MOON — 100% illuminated, rises at sunset The landscape photographer's ally. Rises at sunset, sets at sunrise. All night illumination. Dramatic lighting on terrain, water, architecture. No Milky Way visible but extraordinary landscape light. Best for: Moonlit seascapes, mountain landscapes, architectural photography at night. WANING GIBBOUS — setting before sunrise Rises late — the night starts dark. Moon illuminates landscape in the early morning hours. Excellent for photographers who shoot before dawn. LAST QUARTER — 50% setting before sunrise Mirror of first quarter — rises around midnight. First half of night is dark for astro. Second half has moonlight. WANING CRESCENT — rising before sunrise Very thin. Rises just before dawn. Sky is dark for most of the night. Second-best phase for astro after new moon. MILKY WAY VISIBILITY (Northern Hemisphere) Core visible: approximately late February through October. Best months: April through August. Core direction: South to southwest. Best time: Midnight to 3am during prime months. Requirement: New moon or thin crescent. Bortle 4 sky or darker. THE BORTLE SCALE (dark sky quality) 1 — Exceptional. No light pollution. Zodiacal light and gegenschein visible. 2 — Truly dark. Most observers never experience this. 3 — Rural sky. Milky Way impressive, shows structure. 4 — Rural/suburban transition. Milky Way still a showstopper. 5 — Suburban sky. Milky Way visible but washed out. 6 — Bright suburban. Milky Way faint, only near zenith. 7 — Suburban/urban transition. Milky Way nearly invisible. 8-9 — City sky. No Milky Way. Only brightest stars visible.

Live weather from NOAA api.weather.gov — official US federal weather data. No API key required. US locations only. Allow location access or enter coordinates manually.
READING WEATHER FOR PHOTOGRAPHY CLOUD COVER 0–25% — Clear sky. Harsh directional light midday. Golden hour is spectacular when unobstructed. 25–50% — Partly cloudy. Intermittent soft light. Can be dramatic with light breaking through. 50–75% — Mostly cloudy. Diffused light all day. Flattering for portraits. Boring for landscapes. 75–100% — Overcast. Even, soft, directionless light. Excellent for: portraits, macro, forest, waterfalls. WIND For long exposure: wind above 10mph will blur foliage, water, and clouds — sometimes beautifully, sometimes uncontrollably. For hand-held: wind affects camera stability. Long lenses are most affected. For portraits: wind moves hair. This is either great or terrible. Decide before you arrive. HUMIDITY High humidity haze reduces contrast and color saturation, especially at distance. Landscapes shot through humid haze look flat. Best atmospheric clarity: after a cold front passes, when dew point drops sharply. GOLDEN LIGHT CONDITIONS The best golden hour light often follows afternoon storms — the atmosphere is clean and the light bends dramatically through the clearing edge of departing clouds. Watch for: crepuscular rays, rainbow light, afterglow (the sky 15 minutes after sunset when clouds glow from below). RAIN Rain gives you: wet reflective surfaces, clean streets, dramatic skies, emptier public spaces. Shoot during light rain with a weather-sealed camera or umbrella. Shoot immediately after rain before surfaces dry. FROST AND FOG Morning fog: arrive before dawn. Fog burns off fast — you have 30–60 minutes maximum. Low light through fog is extraordinary. Frost: shoot before the sun hits it. Frost melts in minutes once light arrives.
Hyperfocal
hyperfocal distance · near limit · infinity focus · sharp stars NPF rule
Focus at the hyperfocal distance and everything from half that distance to infinity is acceptably sharp. The single most useful concept in landscape photography that most photographers never use.
Hyperfocal
Sharp Stars
Enter focal length above.
HOW TO USE IT Set your lens to the hyperfocal distance shown above. Everything from the near limit to infinity will be acceptably sharp. This is not perfect sharpness — it is acceptable sharpness, based on the circle of confusion for your sensor. For maximum landscape sharpness: use the hyperfocal distance, not infinity focus. Focusing at infinity wastes depth of field behind infinity where nothing exists.
Crop Calc
crop factor · full-frame equivalent · field of view · effective aperture
A 50mm lens on APS-C does not see like a 50mm lens. It sees like a 75mm lens on full frame. Know your equivalencies before you buy a lens or book a shoot.
Enter focal length and sensor above.
DOF EQUIVALENCY EXPLAINED A 50mm f/1.8 on APS-C gives the same field of view as a 75mm on full frame. But the depth of field equivalent to f/1.8 on full frame requires f/1.2 on APS-C. The background blur you see depends on both field of view AND depth of field. To exactly replicate a full-frame look on APS-C you need a wider lens AND wider aperture. This is why full-frame cameras are prized for portraits — not field of view but depth of field.

BLACK & WHITE CONVERSION — COLOR FILTER EFFECTS When converting color images to black and white, digital "color filters" replicate the effect of physical filters used in the film era. RED FILTER (high contrast, dramatic) Darkens blue sky dramatically — turns it nearly black. Lightens red and orange tones — skin, brick, warm foliage. Classic landscape filter. Makes white clouds pop against dark sky. Use for: dramatic landscapes, architecture, portraits with strong skin tones. ORANGE FILTER (moderate contrast) Less extreme than red. Good general-purpose landscape filter. Darkens blue sky noticeably. Lightens warm tones moderately. Use for: everyday landscape work, street photography, documentary. YELLOW FILTER (subtle) Light control — slight sky darkening, slight skin lightening. The traditional portrait filter. Renders tones closer to how the eye perceives them. Use for: portraits, natural landscapes, documentary work. GREEN FILTER Lightens green foliage — trees and grass become bright and textured. Darkens red tones (skin reads slightly darker — use with care on portraits). Darkens blue sky less than red filter. Use for: forest, botanical, natural landscape photography. BLUE FILTER (rarely used) Lightens blue sky and blue tones. Darkens reds and oranges. Skin renders dark. Creates a moonlit, cold feel. Use for: intentional effect, water, industrial, night-like aesthetics. IN LIGHTROOM / CAPTURE ONE The HSL panel in B&W mode lets you control each color channel's brightness independently. This is more powerful than a single filter — you can combine effects. Raise orange to lighten skin while also raising blue to lighten sky simultaneously. This combination is impossible with a single physical filter.

POSING FUNDAMENTALS THE BODY ANGLE RULE Almost never shoot a subject facing directly at the camera. Turn the body 30–45° to the side. This slims and shapes. The face can then turn back toward the camera — creating a dynamic tension. A body angled away but face looking back is one of the most versatile poses in photography. WEIGHT DISTRIBUTION The hip that carries weight should be away from camera. The free hip pops slightly — creates an S-curve in the body. This applies to all genders — the degree varies, the principle holds. Standing straight with weight equal on both feet reads as flat and formal. CHIN FORWARD AND DOWN The single most universally flattering adjustment. Bring the chin slightly forward (toward camera) and slightly down. This separates the jaw from the neck, defining the jawline and eliminating double chin. Tell subjects: "Bring your forehead toward me slightly." SHOULDERS Dropped shoulders read as relaxed and natural. Raised shoulders read as tension, anxiety, or cold. Have subjects take a breath and exhale — shoulders naturally drop. One shoulder slightly lower than the other adds dynamic asymmetry. THE EYES Where the eyes look defines the mood of the image. Eyes to camera — engagement, directness, connection. Eyes away — introspection, narrative, mystery. Eyes upward — aspiration, youth. Eyes downward — sadness, reflection, intimacy. The catchlight in the eye (reflection of the light source) brings eyes to life. No catchlight = flat, lifeless eyes. HANDS The most difficult thing to pose and the most noticed when done badly. Never let hands hang flat against the body — they look like flippers. Hands at rest: fingers slightly curved, as if holding a very light object. Never show the back of the hand straight to camera — show the edge. For women: fingers together, gentle curve, elegant. For men: looser grip, more angular, natural hang. Give hands something to do: in a pocket, on a surface, touching something relevant.
