Common Histogram Patterns
Key Concepts
📈 ETTR — Expose to the Right Expose as brightly as possible without clipping highlights. A histogram pushed to the right (but not touching the wall) captures maximum sensor data and has the best signal-to-noise ratio. This is especially valuable when shooting RAW — you can pull back highlights in post without introducing noise.
📷 RGB vs Luminance histogram: Most cameras show a luminance (overall brightness) histogram, but some also show separate R, G, B histograms. A luminance histogram can show no clipping while individual colour channels are clipped. Check RGB histograms for critical work — especially in high-saturation scenes.
📸 RAW vs JPEG: The in-camera histogram always shows the JPEG-rendered preview, even when shooting RAW. If your camera applies a high-contrast picture style, the histogram may show blown highlights that aren't actually clipped in the RAW file. Shoot in a flat picture style for more accurate histograms.
🌅 When to deliberately underexpose: In bright sunshine or backlit scenes, protect highlights by underexposing by 1–2 stops. Recover shadows in post — it's much easier to lift underexposed shadows in RAW than to recover blown highlights.
