Everything before Walsworth

CameraSchool

Shutter · Aperture · ISO · Focus · Lenses

Walsworth teaches you how to use Walsworth. This page teaches everything that happens before a photo gets there.

01the whole thing

Three settings that work against each other

Every photo you take is a balance between three numbers.

A camera has one job: let in the right amount of light. There are three ways to control the light, and each one has a different cost. That’s the whole subject.
Everything else is practice.

SHUTTER APERTURE ISO how long light comes in how wide the hole is how hard you amplify Move one. Another has to move back. motion noise how much is in focus
Let in more light with one setting, and you have to let in less with another. The skill isn’t memorizing numbers. It’s knowing which cost you’re willing to pay for this shot.
Use these settings and stop worrying

Manual mode with Auto ISO. You pick the shutter speed and the aperture, because those two decide how the photo looks. The camera picks the ISO, because ISO only fixes brightness. Most professional photographers shoot this way, and it takes away most of the stress.

02the dial

The modes on the mode dial

There are four letters, and we only use one of them. The others are either training wheels or traps.

  • M · Manual
    What we use. You set the shutter speed and aperture. Add Auto ISO, and you control the two settings that decide how the photo looks, with a safety net on the third
  • A / Av · Aperture priority
    You pick the aperture, and the camera picks the shutter speed. It’s fine for portraits and anything that isn’t moving. It’s risky for sports, because in a dark gym the camera will pick 1/60 and ruin the shot
  • S / Tv · Shutter priority
    You pick the shutter speed, and the camera picks the aperture. It’s a good step up for a game if M still feels like too much
  • P · Program
    The camera picks both, and you can adjust a little. Not useful here, and not worth learning
  • AUTO / green box
    Don’t use it. It will pop the flash in a theater, pick 1/30 in a gym, and shoot JPEG. This whole page is here so you never have to touch it
Canon uses different letters

Sony and Nikon call these modes A and S. Canon calls the same modes Av and Tv (for aperture value and time value). Same modes, different letters. It’s the most common reason people pick the wrong mode on the Rebel.

03the buttons

Where the controls are on your camera

Knowing what shutter speed does won’t help if you can’t find it in the dark, thirty seconds before the game starts.

Put every camera in M first. Then:

Sony A7 III · A7 IV · A6700

  • Shutter
    Front dial, by your pointer finger
  • Aperture
    Back dial, by your thumb. If the lens has its own aperture ring, set the ring to A, or the dial on the camera won’t do anything
  • ISO
    Press the right side of the round control wheel on the back, then turn it to change the number. Scroll past the top of the list to get to ISO AUTO
  • Do this once
    In the menu, set ISO AUTO Min. SS to 1/500, so the camera never drops below a usable shutter speed without telling you

Nikon Z5

This is the one everybody complains about, but it’s just one habit to learn: to change ISO, you hold a button and turn a dial.

  • Shutter
    Main command dial, on the back, under your thumb
  • Aperture
    Sub-command dial, on the front, under your pointer finger
  • ISO
    Hold the ISO button on top and turn the back dial to change the number. Keep holding it and turn the front dial to turn Auto ISO on or off
  • The trick
    Most people never find that second dial. Turning the front dial while holding ISO is the only way to get to Auto ISO without going into the menu

Canon Rebel T5

This one is a little awkward because it only has one dial, so changing the aperture takes a button too.

  • Shutter
    Main dial, on top, behind the shutter button
  • Aperture
    In M mode: hold the Av button (marked Av ±, on the back of the camera) and turn the main dial
  • ISO
    Press the ISO button on top, then pick from the list
  • Reminder
    On this camera, shutter priority is Tv and aperture priority is Av, not S and A
Learn it blind

Before you shoot anything important, practice changing all three settings without looking at the camera. In a gym, you’re watching the game, not the camera. The difference between a photographer and someone holding a camera is whether they have to look down.

If a dial doesn’t do anything, you’re in the wrong mode. The aperture dial doesn’t work in S/Tv, and the shutter dial doesn’t work in A/Av. The camera isn’t broken. It’s doing exactly what the mode dial tells it to.

04time

Shutter speed

How long the camera’s sensor collects light. It decides whether a moving person looks sharp or looks like a smear.

1/60 SLOW 1/800 FAST smear a person
Same player, same gym, two shutter speeds. The photo on the left isn’t artistic. It’s unusable, and it’s the most common way sports pages get ruined.

The number to remember: 1/500. Slower than that, and moving people start to blur. Basketball and volleyball need 1/500 to 1/800. Football and track outside can use 1/1000, because there’s plenty of light. A student sitting in class is fine at 1/125.

A slower shutter lets in more light, so in a dark gym your first idea will be to slow it down.

Don’t. That’s how you come back with two hundred blurry photos. Keep the shutter fast, open the aperture wide, and let ISO handle the rest.

05the hole

Aperture

How wide the lens opens. It decides how much light gets in, and how much of the photo is in focus.

f/1.8 WIDE OPEN f/11 STOPPED DOWN lots of light a little light shallow deep what is sharp what is sharp
Here’s the confusing part: a smaller number means a bigger opening. f/1.8 is wide open, and f/11 is almost closed. Everyone thinks this is backwards at first.
You’ll get used to it.

A wide opening (small f-number) does two things. It lets in lots of light, which saves you in a gym. And it makes only a thin slice of the photo sharp, so your subject is in focus and the background turns soft and blurry. That’s the look people mean when they say a photo looks professional.

A narrow opening (big f-number) does the opposite. Less light, but more of the photo is sharp. Use it when everyone in a group photo needs to be in focus, which is most of the time in a yearbook.

06the volume knob

ISO

How much the camera boosts the light it got. It makes photos brighter for free, but it adds grain.

Shutter speed and aperture control the real light coming in.

ISO doesn’t. It boosts the light that already came in, like turning up the volume on a song. And like turning up the volume, it also turns up the static. That static is called noise, and it looks like colored speckles in the dark parts of the photo.

Don’t be scared of noise.

A slightly grainy photo of the winning shot is still a great photo. A clean, blurry one is useless. The full-frame cameras look fine up to ISO 6400 and often higher, and Lightroom can clean up more grain than you’d think.

The order to set things

Set the shutter speed first, then the aperture, and let ISO handle whatever is left. Every bad gym photo this program has ever taken came from doing it in the wrong order.

07what is sharp

Deep focus and shallow focus

One subject that stands out, or a whole scene that’s sharp. Choose on purpose.

Shallow

Subject sharp, background blurry

Open the aperture wide, get closer to your subject, and leave space between them and the background. A longer lens makes the blur even stronger.

Use it for: portraits, one player, a hand on an instrument, or anything where the background doesn’t matter.

Deep

Everything holds

Set the aperture to f/8 or f/11, step back, and use a wider lens. This needs more light, so do it outside or with a tripod.

Use it for: group shots, a whole classroom, a stage set, or anything where the setting is the story.

Autofocus matters more than either one. Set the camera to continuous autofocus (AF-C on Sony and Nikon, AI Servo on Canon) for anything that moves, which at school is almost everything. Single-shot autofocus locks on once, and then your photo goes soft as your subject moves.

08the lens

Lenses, and why the same lens acts like two different lenses

The camera captures the photo. The lens decides what the photo looks like.

A7 III / A7 IV / Z5 full frame · 1.0x A6700 APS-C · 1.5x Rebel T5 APS-C · 1.6x same lens, same spot, three different photos
Put a 50mm lens on the A7 IV, and you get the outer frame. Put the same lens on the A6700, and you get the blue box, 1.5 times tighter. On the Rebel T5, it’s even tighter.

Crop factor isn’t worse. It just frames the photo differently.

A 50mm lens acts like a 75mm on the A6700, and about an 80mm on the T5. That makes those cameras great for zooming in across a gym, and bad for fitting a whole classroom in the frame.

Lenses only fit their own brand. Sony uses E, Canon uses EF/EF-S, and Nikon uses Z. A Canon lens won’t fit on a Sony camera, and it won’t work if you force it. The camera isn’t broken.
Grab the lens that came with the camera.

09the payoff

The four recipes

These four situations cover almost everything in the book. These settings are starting points, not rules. Take one photo, look at the screen, and adjust.

The gymbasketball · volleyball · wrestling
  • ModeManual + Auto ISO
  • Shutter1/500 to 1/800
  • ApertureWide open
  • ISO cap12800
  • FocusAF-C, zone
  • DriveBurst

Why: a gym is much darker than it looks to your eyes, and the people in it are running fast. It’s the hardest lighting at school, and it’s why most school sports photos are bad.

Shoot from low down, at the end line, and wait for faces instead of backs. Anything faster than 1/500 and under ISO 12800 can be cleaned up in Lightroom.

The stagetheater · dance · band
  • Shutter1/250
  • ApertureWide open
  • ISO cap12800
  • MeteringSpot
  • FocusAF-C, eye
  • FlashNever

Why: a lit face on a dark stage confuses the camera’s light meter. Spot metering tells the camera to get the face right and let everything else go dark, which is what your eyes see anyway.

Never use flash. It ruins the stage lighting, it blinds the performers, and you’ll be asked to leave.

Midday outdoorfootball · track · rallies
  • Shutter1/1000+
  • Aperturef/4 to f/5.6
  • ISO100 to 400
  • FocusAF-C, tracking
  • WatchBlown sky
  • TrickSun behind you

Why: you finally have plenty of light, so use it for a fast shutter speed. The new problem is contrast: bright white skies and dark shadows around people’s eyes.

Shoot with the sun behind you, or find shade. A cloudy day isn’t bad weather.
It’s the best light you’ll get all year.

The classroomacademics · electives · AVPA/CTE
  • Shutter1/125
  • Aperturef/2.8 wide
  • ISO1600 to 6400
  • Shutter modeSilent
  • FlashNever
  • AttitudeBoring

Why: classroom lights are dim and a little green, and you’re a guest in someone’s lesson. Use the silent shutter if the camera has one.

The real trick here is patience. Everyone acts for the camera for the first two minutes, then they forget you’re there.
The best photos come after that.

The Workshops

There are seven workshops, one in the first week of each month from September through March. They’re required for everyone in Content and the photographers in Outreach. Everyone else is welcome, and it counts toward your hours.

Each one is a short lesson, then a real shoot. None of it is graded.
It’s where you get good before a checkpoint depends on it.

W1 · The Camera TestSeptember · CP1

You learn: the three settings, the mode dial, and where every control is on your camera. Turn RAW on and check the card.

You turn in: six photos of one subject, straight from the camera, with no editing. The same subject at 1/60 and 1/800. The same subject at your widest aperture and at f/11. The same subject at ISO 100 and ISO 6400. Plus a screenshot of the card showing .ARW, .NEF, or .CR2 files.

What good looks like: your six photos really show the three differences, and you shot in RAW. If your two shutter photos look the same, you changed the mode instead of the setting.

W2 · Cull and CorrectOctober · CP1

You learn: Lightroom Classic. Import with ADD, mark photos with P and X, filter to your picks, fix exposure and white balance, use Sync Settings on a group of photos, and export with the class preset.

You turn in: one real event folder, named correctly, with photos in originals and selects, the link posted in PHOTO DRIVE LINKS the right way, and at least 40 photos narrowed down to 20 or fewer.

What good looks like: how well you picked, not how well you edited. Twenty good photos beat sixty okay ones.
Turning in everything you shot isn’t picking.

W3 · The GymNovember · CP2

You learn: the hardest lighting at school. Auto ISO with a minimum shutter speed, continuous autofocus, burst mode, shooting from the end line, and why slowing down the shutter is the wrong move.

You turn in: one whole home game. Ten usable photos, at least four with faces, and at least two of the bench or the crowd.

What good looks like: usable, which means sharp enough to print at half a page. This workshop decides whether the sports section is any good.
It’s also the one people skip.

W4 · PeopleDecember · CP3

You learn: portraits and interviews. Where to put someone so the light looks good, how to ask a question that gets a real answer, and how to get a name spelled right the first time.

You turn in: a portrait of someone you didn’t already know, plus three usable quotes from them, with the spelling of their name confirmed in writing.

What good looks like: the quotes matter as much as the photo. “It was fun” isn’t a quote. And a name you misspell here is the same name that gets printed a thousand times.

W5 · Shooting for a SpreadJanuary · CP4

You learn: a page needs a main photo, vertical photos, horizontal photos, a close-up detail, and space for text. You’re not just taking photos. You’re filling a layout someone planned.

You turn in: a shot list made from a real approved plan, then the photos that match it: one main photo, two verticals, two horizontals, and one detail.

What good looks like: a designer could build the spread from your photos without asking you for anything else. This workshop connects Outreach to Design.

W6 · Color and PrepressFebruary · CP5

You learn: RGB vs. CMYK, why bright neon colors print duller, resolution vs. DPI, and what the export preset really does.

You turn in: the same photo exported three ways: correctly, at half resolution, and in the wrong color mode. Add one sentence for each, explaining what would happen if it went to the printer.

What good looks like: you can explain each mistake, not just make it. Anyone can export something wrong.
The job is knowing which mistakes would ruin a printed page.

W7 · The EmergencyMarch · CP6

You learn: how to proof and hunt for mistakes when time is short. What to check, in what order, and what can’t be fixed once the book is at the printer.

You turn in: a proof of someone else’s finished spread, with every mistake found and written down, plus one written fix for the worst one.

What good looks like: what you caught, and what you missed that I find later. The last workshop of the year is the closest to the real job.

Why bother

Everything you turn in above is work the book needs anyway. Nobody is taking practice photos that get thrown away. W2 is an event that has to be uploaded anyway, W3 is a game that has to be covered, and W5 is a spread that has to be filled. The workshop costs you nothing.
Missing the checkpoint does.

10the cage

Which camera for which job

  • Fast & unpredictable
    A7 IV, A6700. Basketball, soccer, wrestling, rallies. About 10 photos a second, with modern subject tracking
  • Controlled & well lit
    Z5, A7 III. Portraits, staff, academics, stage. The Z5 shoots 4.5 photos a second, which is plenty here and not enough for a game
  • Walking around 4th period
    A6700. The lightest, and the least noticeable when you walk into someone’s classroom
  • Backup & learning
    Canon Rebel T5. Every rule on this page still applies to it
  • Can’t be redone
    Graduation, the last home game, a senior photo session: use a camera with two card slots, and turn on backup recording. The Z5 and A7 IV both have it

Before you leave the room, set the camera to RAW and check that the card is saving .ARW, .NEF, or .CR2 files. The menu steps for every camera are on the main page under The Pipeline.

The rules of the gear cage

A camera is the most expensive thing you’ll be handed this year. Every rule below exists because someone already broke it.

Four things you never do. Not even once, not even carefully

Never touch the sensor. Not with a finger, a cloth, your shirt, or canned air.

On these cameras, the sensor sits right behind the lens mount with nothing covering it. One fingerprint means a repair, not a quick clean. If you see dust on it, put the cap on and tell a gear lead.
Don’t try to fix it yourself.

Never leave the sensor uncovered.

When the lens comes off, put the body cap on right away, before you do anything else. Swapping lenses takes ten seconds: point the camera down, hold the new lens ready in your other hand, and take one off and put the other on in one motion. Never do it in wind, over a dusty gym floor, or in the rain.

Never touch the glass on the front or back of any lens. The oil from one fingertip damages the coating over a few weeks, and it can’t be cleaned off later. Keep caps on both ends whenever the lens isn’t on a camera. If it’s dirty, use the blower first, then a real lens cloth. Never use your sleeve.

Never take gear without checking it out. Every camera, every lens, every card, every time, in #yb-equipment. If a camera isn’t checked out, nobody is responsible for it.
And if it goes missing, that’s the only thing anyone will talk about.

  • Strap
    On your neck or wrist before you walk anywhere. Every camera this program has ever dropped was dropped between a table and a door
  • Caps
    The body cap and both lens caps stay with the camera, and they go back on as soon as you stop shooting. A cap in your pocket is a cap you’re about to lose
  • Cards
    Never take out a card while the light is blinking. Never erase a card yourself. A gear lead erases it after your upload is checked, just like The Pipeline says
  • Batteries
    Charge them before you return the camera. Don’t leave them in a hot car or in your backpack for a week. A dead camera at a game means nobody covered the game
  • Wet or dusty
    Rain, a pool deck, sprinklers, or dust blowing on the field: the camera goes in the bag, and the shoot is over. No photo is worth the camera
  • Return
    Put it back where you got it, with caps on, strap on, charged, and checked back in. If it has a scratch it didn’t have this morning, tell us
If you break something

Say so the same day in #yb-equipment. Accidents happen. They cost five CRED points, the same as being late, and then it’s over. Hiding it is different. Damage that was reckless or hidden can cost up to forty points. Even worse, the next person who checks out that camera finds out at a game.
Be the person who speaks up.

Coming

The lens list. Every lens in the cabinet, and which one to use for each situation: the gym, the stage, a portrait, a wide classroom, or a close-up detail. We’re counting them now.

Coming

Example photos for each set of settings, taken with our own cameras in our own gym, so you can see what these settings really look like.
