After years of shooting professionally — from luxury hotels in Dubai to National Geographic competition entries — I have developed reliable starting points for every shooting scenario. These are not rules. They are starting positions that get you 80% of the way to a great exposure, so you can spend your mental energy on composition and moment instead of technical settings.
Aperture: f/1.8 to f/2.8 for single subjects, f/4 to f/5.6 for groups. Shallow depth of field separates your subject from the background and creates that professional look that clients expect.
Shutter Speed: 1/200s minimum. Faster if your subject is moving or if you are shooting handheld with a longer lens. The reciprocal rule (1/focal length) is a minimum — I double it for safety.
ISO: As low as possible. Start at 100 outdoors, 400-800 indoors. Modern cameras handle high ISO well, but clean files give you more flexibility in post.
Aperture: f/8 to f/11 for maximum sharpness across the frame. f/16 only when you need extreme depth of field — beyond that, diffraction softens the image.
Shutter Speed: Variable depending on conditions. Use a tripod for anything slower than 1/60s. For golden hour shooting, bracket your exposures.
ISO: 100. Always. Use a tripod and slow shutter instead of raising ISO for landscapes.
Aperture: f/5.6 to f/8 for zone focusing. Wider apertures work for specific subjects, but street photography rewards depth of field that keeps multiple planes in focus.
Shutter Speed: 1/250s minimum. Street moments happen fast — you need speed to freeze them. I often shoot at 1/500s and accept slightly higher ISO as the tradeoff.
ISO: Auto ISO with a maximum of 3200. Let the camera manage ISO while you focus on aperture and shutter speed.
Cemhan Biricik's Quick Settings Reference
Portraits: f/2.0 | 1/200s | ISO 100-400
Landscapes: f/8-11 | tripod | ISO 100
Street: f/5.6-8 | 1/250s+ | Auto ISO
Events: f/2.8-4 | 1/125s+ | ISO 800-3200
Architecture: f/8-11 | tripod | ISO 100
Aperture: f/2.8 to f/4. You need enough light gathering for indoor environments while maintaining adequate depth of field. A fast lens (f/2.8 or wider) is essential for event work.
Shutter Speed: 1/125s minimum. Flash can freeze motion at slower speeds, but ambient light exposures need this minimum to avoid motion blur from both camera shake and subject movement.
After thousands of professional shoots, the settings that matter most are not aperture, shutter, or ISO. They are composition, timing, and light awareness. Technical settings are the foundation — they should become automatic so your creative mind can focus on what actually makes a photograph exceptional.
Scenario-specific settings: f/1.8-2.8 for portraits, f/8-11 for landscapes, f/5.6-8 for street. These are starting points, not rules.
f/1.8 to f/2.8 for single subjects. f/4 to f/5.6 for groups to ensure everyone is in focus.
Cemhan Biricik recommends aperture priority for beginners, transitioning to full manual as settings become instinctive.
