How PhotographyWhisperer works

Three steps: describe the scene, read back four numbers, dial them into your camera. No app pairing, no brand-specific menus, just the standard controls every manual-mode camera has.

1. 1

   Describe the scene

   Tell us the light and the subject in your own words: what you're shooting, how much light there is, and whether anything is moving. “Kid running across the yard at golden hour” or “candlelit table at a wedding reception” is enough, you don't need to know f-stops or shutter speed going in.

   Two details change the answer the most: how much light is actually in the scene, and how fast your subject is moving. Light ranges further than people expect, and each step down below is roughly one stop less light to work with. If you know your camera and lens, mention those too, depth of field and the handholdable shutter floor both shift with focal length.

   Light (EV)

   EV 15

   bright sun

   EV 12

   open shade

   EV 5-7

   lit indoor room

   Bright sun is the basis of the sunny-16 rule: f/16 at 1/ISO.

   Motion (shutter speed)

   1/125s

   walking

   1/500s

   running kid or dog

   1/1000s+

   fast sport or birds in flight

2. 2

   Read the settings

   You get back four values: ISO, aperture, shutter speed, and white balance, the same exposure triangle every manual camera uses, plus color temperature. They trade against each other in stops, open the aperture one stop and you can cut the shutter time in half, from 1/125s to 1/250s, or halve the ISO instead, and land at the same overall exposure. Each response tells you which of the three we prioritized for your scene and why, rather than handing you a number with no reasoning attached.

   Aperture sets how much is in focus as much as it sets exposure. ISO is the number most likely to move scene to scene, climbing past the ranges below only when shutter speed matters more than a clean file.

   Aperture

   f/1.8-2.8

   single subject, soft background

   f/4-5.6

   couple or small group

   f/8-11

   landscape; sharpest for most lenses

   f/16

   everything in focus, foreground to horizon

   ISO

   800-1600

   lit city street

   1600-3200

   dim indoor reception

   3200-6400

   candlelight or handheld night

   Dial them in

   Set aperture and ISO on your camera as given, then set shutter speed, or let your camera's manual or aperture-priority mode hold it for you. If you're shooting without a tripod, keep an eye on the reciprocal rule folded into the shutter speed we give you: roughly 1/focal length to avoid handshake blur, about 1/50s on a 50mm lens, 1/200s on a 200mm, a couple of stops slower if your lens or body has stabilization.

   White balance can usually be set from the nearest preset on your camera rather than typed in as a raw Kelvin value, Daylight, Cloudy, Tungsten, or Shade all correspond to a rough color temperature range. Shoot a test frame, check it against the scene, and adjust ISO or shutter speed by a stop if the light was brighter or dimmer than described. The reasoning behind each value is there so you can make that adjustment yourself instead of guessing from scratch next time the light changes.
