☀️
The Sunny 16 Rule
On a bright, clear 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 is 1/125s (EV 15.0).
f/16 • Shutter = 1/ISO • Clear Sunlight
🤲
The Handheld Reciprocal Rule
To prevent hand-shake motion blur without image stabilization, your minimum shutter speed must equal at least 1 / (Focal Length × Crop Factor). For a 200mm lens on APS-C, minimum speed is 1/300s (or 1/500s).
Min Shutter = 1 / (Focal Length × Crop Factor)
🌙
The Looney 11 Lunar Rule
The Moon is a sunlit rocky celestial body floating in black space. At f/11, set your shutter speed equal to your ISO (ISO 100 = 1/125s) to capture crisp craters without white blowout.

Zone Focusing & Hyperfocal
In street and landscape photography, setting your lens to its hyperfocal distance ensures everything from half that distance to infinity remains in acceptable focus, completely eliminating autofocus lag.

Frequently Asked Questions
Expert answers to the most common questions regarding camera exposure, mode dials, autofocus tracking, and shooting settings.
For beginners, Aperture Priority (A/Av) with Auto ISO is the ideal starting point. It gives you creative control over background blur (aperture) while the camera automatically selects a safe shutter speed to prevent blurry images. Set minimum shutter speed in camera menus to 1/125s for handheld shooting.
Professional photographers use both! Aperture Priority (A/Av) is favored for rapidly changing natural light like street, travel, and candid events. Manual mode (M) is essential when lighting is strictly controlled (studio strobes, flash photography, fireworks, astrophotography) or when you want 100% exposure consistency across consecutive frames.
Yes! Modern digital sensors have exceptional high-ISO noise handling and ISO-invariance. Setting Auto ISO with a maximum ceiling (e.g. ISO 6400) and a minimum shutter speed threshold (e.g. 1/500s for action) allows you to focus on timing, composition, and focus without worrying about underexposure.
Camera light meters assume scenes reflect an average of 18% middle gray. In high-key environments filled with pristine white snow or bright sandy beaches, the meter reduces exposure, causing white snow to render as dirty gray. Adding +1.3 to +1.7 EV of exposure compensation restores bright, natural white snow.
Always turn Image Stabilization (IBIS or lens IS/VR/OSS) OFF when mounted firmly on a tripod during long exposures. When the camera detects zero movement, the gyroscopic stabilization sensors can create a feedback loop and induce micro-vibrations, resulting in soft photos.
AF-S (Single Shot AF) locks focus once when you half-press the shutter button; if the subject moves, focus will be lost. Use AF-S for static landscapes and stationary architecture. AF-C (Continuous AF / AI Servo) continuously recalculates focus as long as the shutter is held, actively tracking moving subjects like athletes, children, and flying birds.
