Basic DSLR settings that will improve your photography.
Master your DSLR camera settings to take control of exposure, focus, and lighting for sharper, more professional looking photos.
A guide to DSLR camera settings.
Mastering the essential DSLR camera settings can transform the quality of your photography, giving you creative control over your images. Understanding how settings like aperture, shutter speed, and ISO work together allows you to move beyond automatic modes and start capturing photos exactly how you envision them. This guide breaks down the core settings every photographer should know, providing tips on adjusting them for different situations to consistently achieve stunning results. Explore this complete overview of DSLR cameras to understand how they work and why they remain a favourite among photographers.
Understanding the exposure triangle.
The foundation of DSLR photography lies in the exposure triangle - aperture, shutter speed, and ISO. These three camera settings control the exposure of your photos and work together to produce a well-balanced image. Learn the fundamentals of exposure in photography and how light influences your images.
Aperture.
Aperture refers to the opening in your lens that allows light to enter the camera. It is measured in f-stops (e.g., f/2.8, f/5.6, f/11).
- A lower f-stop (e.g., f/1.8) creates a larger opening, letting in more light and producing a shallow depth of field (blurry background), ideal for portraits.
- A higher f-stop (e.g., f/11) creates a smaller opening, letting in less light and resulting in a greater depth of field, suitable for landscapes where you want everything in focus.
Shutter speed.
Shutter speed controls the length of time the camera shutter remains open, allowing light to hit the sensor.
- A fast shutter speed (e.g., 1/1000s) freezes motion, perfect for sports and wildlife photography.
- A slow shutter speed (e.g., 1/30s or slower) captures motion blur, often used in long exposure shots like waterfalls or light trails.
Tip: When shooting handheld, use a shutter speed at least as fast as your focal length (e.g., 1/50s for a 50mm lens) to avoid camera shake.

ISO.
ISO measures the camera sensor’s sensitivity to light.
- A low ISO (e.g., 100) is best for bright lighting conditions, producing cleaner images with less noise.
- A high ISO (e.g., 3200 or above) is useful in low-light situations but can introduce grain or digital noise.
Focusing modes for sharp images.
Achieving precise focus is vital for clear, sharp photos. DSLRs offer different focusing modes to suit various subjects:
- Autofocus Single (AF-S): Locks focus when you half-press the shutter button. Best for still subjects like landscapes and portraits.
- Autofocus Continuous (AF-C): Continuously adjusts focus while the shutter button is half-pressed. Ideal for moving subjects like wildlife or sports.
- Manual Focus: Allows complete control over focusing. Useful for macro photography and low-light conditions where autofocus may struggle.
White balance for accurate colours.
White balance ensures that your photos capture accurate colours based on the light source. Adjusting white balance prevents images from appearing too warm (yellow) or too cool (blue).
- Auto White Balance (AWB): The camera evaluates the scene and sets the white balance automatically. Suitable for general use.
- Daylight, Cloudy, Tungsten, Fluorescent presets: Match your white balance setting to the lighting conditions.
- Custom White Balance: Manually set white balance using a neutral grey card for the most accurate colours.
Metering modes for correct exposure.
Metering modes determine how your DSLR measures light to calculate the correct exposure.
- Evaluative (Matrix) Metering: Considers the entire frame. Useful for most general photography.
- Centre-Weighted Metering: Prioritises the centre of the frame. Suitable for portraits.
- Spot Metering: Measures light from a small area (e.g., the subject’s face). Great for high-contrast scenes.
Tip: Use exposure compensation (+/-) to make minor adjustments to your exposure when the metering mode doesn’t produce the desired result.
Practical tips for different shooting scenarios.
- Bright outdoor conditions: Use a low ISO (100-200), fast shutter speed, and narrow aperture (f/8 to f/16) for sharp images.
- Low-light environments: Increase ISO (800-3200), open the aperture (f/2.8 or lower), and reduce shutter speed if using a tripod.
- Fast-moving subjects: Set a fast shutter speed (1/1000s or faster) and use AF-C mode for continuous focusing.
- Portraits: Use a wide aperture (f/1.8 to f/4) for a blurred background and set white balance based on the lighting.
Experiment with manual mode.
Switching to manual mode allows you to control aperture, shutter speed, and ISO simultaneously. This offers the most creative freedom and helps you understand how each setting influences your photo.
- Practice in different lighting conditions to develop confidence.
- Take test shots and adjust settings based on your results.
- Review your images and check the histogram (a graph showing exposure levels) to ensure balanced highlights and shadows.
Combining an understanding of aperture, shutter speed, ISO, focus, white balance, and metering modes empowers you to adapt to any shooting environment. As you gain experience, adjusting camera settings will become second nature, allowing you to focus on capturing the perfect shot.
