What the differences suggest
How to read the analysis
These are measurements calculated on your device, not an AI critique or a quality ranking. Each entire image is sampled at up to 768 pixels on its longest side using browser-decoded sRGB pixels. Non-opaque pixels are excluded. Display cropping does not change the analysis.
Brightness is weighted sRGB channel intensity (0–100); contrast is its standard deviation. Saturation is mean HSV saturation. Near-black means all channels ≤ 5; near-white means all channels ≥ 250. The channel highlight indicator counts pixels with any channel ≥ 250. These are clues, not proof of lost RAW detail.
Different subjects, crops, lighting, and color profiles can explain differences. Higher contrast or saturation is not automatically better. Inspect focus, halos, and fine texture at 100% in a color-managed editor.
Mean RGB describes average color channels, not white balance accuracy. Detail is mean horizontal neighbor intensity difference at the sampled resolution; it can rise with texture, noise or sharpening and is not a focus or quality score.
