SUMMARY
Dynamic range, measured in stops, defines the difference between the brightest and darkest tones a camera sensor can record with usable detail. While megapixels offer more detail, dynamic range is crucial for preventing blown-out highlights and recovering shadow information in post-processing. Modern full-frame cameras typically offer 13-15 stops, significantly impacting image quality compared to older models or smartphones. Understanding that sensors handle highlights and shadows differently—highlights clip to pure white while shadows retain recoverable data—leads to the advice to 'expose for the highlights and recover the shadows.' This makes cameras with higher dynamic range more forgiving and capable of producing usable images from challenging lighting conditions.
TAKEAWAYS
Dynamic range, not megapixels, dictates detail capture in highlights and shadows.
It is measured in stops, representing the range between brightest and darkest recordable tones.
Modern sensors capture more dynamic range, allowing for better shadow recovery than highlight recovery.
Exposing for highlights and recovering shadows in post-processing is a key strategy for usable images.
