Unit
- Aperture (f-stop): Controls depth of field and light entry. For landscapes, use f/8 to f/11 for sharpness across the frame. Smaller apertures (f/16+) risk diffraction softening, especially on high-resolution sensors.
- Shutter Speed: Determines motion blur. Use fast speeds (>1/500s) to freeze wind-blown leaves or water; slow speeds (several seconds) to blur waterfalls or clouds. A sturdy tripod is essential for long exposures.
- ISO: Adjust sensor sensitivity. Keep ISO at base (100 or 200) to maximize dynamic range and minimize noise. Raise only when shutter speed becomes too slow for handholding or subject movement.
- Focus Mode: Use single-point autofocus or manual focus. For distant scenes, autofocus on a contrast edge about one-third into the scene; for close foregrounds, manual focus and use live view magnification to ensure sharpness.
- Metering Mode: Evaluative/matrix metering works for most evenly lit scenes. For high contrast, switch to spot metering on a midtone area and use exposure compensation to avoid clipping highlights or shadows.
- White Balance: Set manually using Kelvin temperature for consistency. Daylight scenes are around 5500K; golden hour is warmer (3000-4000K); overcast is cooler (6500-7500K). Shooting RAW allows flexible adjustment later.
- Drive Mode: Use single-shot for static landscapes; use 2-second or 10-second self-timer to avoid mirror slap vibration. For bracketed exposures, use continuous low-speed to capture multiple frames.
- Image Quality: Always shoot RAW + JPEG fine. RAW preserves maximum data for post-processing; JPEG provides a quick reference. Set picture style to neutral or landscape for a flat RAW preview.
- Histogram Review: Use the live histogram to evaluate exposure while shooting. Aim for a bell shaped curve that does not touch the left or right edges. If the histogram is clipped on either side, adjust exposure compensation to preserve highlight and shadow detail across the scene.
- Tripod Stability: Choose a sturdy tripod with a reliable ball head rated for your camera and lens weight. Extend the thickest leg sections first and avoid raising the center column unnecessarily. Use a hook on the center column to hang your bag for added weight and stability in windy conditions.
- Polarizing Filter: Attach a circular polarizer to reduce glare from water, wet rocks, and foliage. Rotate the filter while looking through the viewfinder to maximize color saturation and contrast in the sky. Avoid using a polarizer with wide angle lenses on clear blue skies to prevent uneven darkening across the frame.
Design Principle
Principle: Zone System Adaptation for Digital
Definition: A systematic method to visualize and control tonal range in the final print, adapted from Ansel Adams black-and-white workflow. In digital, it involves exposing to the right (ETTR) to maximize signal-to-noise ratio while preserving highlight detail.
Application: When evaluating a scene, identify the brightest (Zone VII-VIII) and darkest (Zone II-III) areas. Set exposure so that the most important highlight clips just below maximum (histogram right edge). This ensures shadow detail is captured with minimal noise, allowing smooth tonemapping in post-processing.
Quick Revision
- Aperture f/8-f/11 gives optimal sharpness for landscape scenes; avoid f/16+ to prevent diffraction.
- Shutter speed choice depends on desired motion effect and subject stability.
- Base ISO (100-200) preserves dynamic range and reduces noise.
- Use manual focus or single-point AF with live view for precise focus.
- Spot meter on midtones for high-contrast scenes; use exposure compensation.
- Set white balance manually or shoot RAW for post flexibility.
- Self-timer or remote release prevents camera shake.
- Always shoot RAW for maximum editing latitude.
