What is the Exposure Triangle in photography?

The Exposure Triangle is the fundamental relationship between Aperture, Shutter Speed, and ISO. Together, these three controls determine the brightness of your image while creating distinct creative effects: depth of field, motion blur or freeze, and digital grain.

How does this camera simulator work?

The PicDriver simulator calculates exact optical physics formulas directly in your web browser. It computes Exposure Value (EV), depth-of-field near and far limits based on sensor circle of confusion, motion blur dynamics from shutter duration, and sensor noise simulation.

What camera settings should I use for portraits?

For individual portraits, use a wide aperture like f/1.4 to f/2.8 to blur the background, a shutter speed of at least 1/250s to avoid camera shake and capture sharp eyes, and the lowest native ISO (100) for maximum clarity.

What camera settings are best for landscapes?

For landscape photography, choose an aperture of f/8 to f/11 for edge-to-edge optical sharpness without diffraction, base ISO 100, and a tripod to allow whatever shutter speed is required for optimal exposure.

What is an ND filter and when should I use one?

A Neutral Density (ND) filter acts like sunglasses for your camera lens, reducing the amount of light entering the sensor without altering color balance. It allows photographers to use slow shutter speeds in bright sunlight to create silky water effects or wide apertures without overexposure.

The Master Guide to Camera Controls & Exposure Physics

Essential optical principles every photographer should understand.

🔺

The Law of Exposure Reciprocity

Exposure is governed by three interconnected variables: Aperture (light volume), Shutter Speed (light duration), and ISO (signal amplification). If you decrease one stop of light by stopping down your aperture (e.g. f/2.8 to f/4.0), you must add one stop via slower shutter speed or higher ISO to preserve identical image brightness.

EV = log2(N² / t) - log2(S / 100)

☀️

The Sunny 16 Rule

On a bright, unshaded sunny day, set your aperture to f/16 and your shutter speed to the reciprocal of your ISO value. For example, at ISO 100, your shutter speed should be 1/100s (or 1/125s) at f/16. From this baseline, open up 1 stop to f/11 for slight haze, 2 stops to f/8 for overcast, or 3 stops to f/5.6 for heavy shade.

Aperture: f/16 • Shutter: 1 / ISO

✋

The Reciprocal Handholding Rule

To prevent image softness caused by natural hand tremors when shooting without a tripod, your minimum handheld shutter speed should equal or exceed 1 divided by your focal length (on a 35mm full frame sensor). For a 200mm telephoto lens, shoot at 1/200s or faster. For crop sensors, multiply by the crop factor first.

Min Shutter = 1 / (Focal Length × Crop Factor)

Frequently Asked Questions

Everything you need to know about digital camera settings, exposure reciprocity, and interactive simulation.

The Exposure Triangle represents the relationship between Aperture (lens opening), Shutter Speed (exposure duration), and ISO (sensor amplification). Changing any one of these three settings alters both the total brightness of your photograph and its artistic characteristics: depth of field, motion capture, and digital grain.

The simulator runs mathematical physics formulas locally in your browser. It calculates Exposure Value (EV), optical Circle of Confusion (CoC), hyperfocal distances, motion vectors scaled to shutter fractions, and synthetic Poisson/Gaussian sensor grain to visually recreate what a physical mirrorless or DSLR camera captures.

For individual portraits, use a wide aperture like f/1.4 to f/2.8 to blur the background into creamy bokeh, a shutter speed of at least 1/250s to prevent micro-blur on eyes, and your camera's native base ISO (typically ISO 100) for maximum dynamic range and zero noise.

For landscapes, use an aperture in your lens's optical sweet spot between f/8 and f/11 for edge-to-edge sharpness without diffraction softening. Keep ISO at 100 and mount your camera on a sturdy tripod so you can use whatever shutter speed is required for balanced exposure.

A Neutral Density (ND) filter reduces the quantity of light entering your lens across all wavelengths equally. It enables you to shoot with slow shutter speeds in broad daylight to create silky waterfalls and glassy ocean waves, or to shoot wide open at f/1.4 without exceeding your camera's fastest shutter speed.
