Brightness and contrast are broad adjustments: they can rescue an underexposed image or make it harsh in seconds. Use the live preview to correct the overall tone first, then refine highlights, shadows, gamma, temperature, clarity, or vibrance only when the photograph actually needs those changes.
Raise brightness cautiously when the entire frame is too dark. If faces or foreground details are hidden but the sky is already bright, lifting shadows is usually safer than pushing every pixel upward. Lower highlights when pale areas lose texture. Watch white clothing, clouds, screens, and reflective surfaces because clipped highlights become flat patches that another slider cannot reconstruct.
Increasing contrast expands the difference between light and dark areas, which can add depth to a flat photo. Too much contrast crushes shadow detail and clips highlights. Decreasing it can help a harsh scan or midday photo, but an excessive reduction produces gray, weak tones. Compare the preview at normal size and zoom into hair, dark fabric, clouds, and text before deciding.
Exposure, gamma, saturation, vibrance, temperature, tint, clarity, and sharpening can interact. Correct light first, then color, then local-looking detail controls such as clarity or sharpening. Presets are useful starting points, not finished edits. Use Undo to compare decisions and Reset when accumulated adjustments make it difficult to identify which control caused halos, noise, or unnatural skin tones.
Review the adjusted photo on the details most likely to reveal an overcorrection.

Both affect lightness, but they do not always distribute the change identically. Use the preview rather than relying on the label: brightness is useful for an overall shift, while exposure can feel stronger in brighter tonal regions depending on the implementation.
Increase shadows first when the foreground is the main problem, then make a smaller overall brightness or exposure adjustment. Reduce highlights if the sky begins losing texture. A single global slider cannot recover detail that was clipped when the photo was captured.
Dark regions contain less clean signal. Brightening them also makes sensor noise and compression artifacts easier to see. Stop when the important detail becomes readable, and avoid heavy clarity or sharpening that emphasizes the noise further.
Very high contrast can turn dark areas into featureless black and bright areas into featureless white. It can also make skin, text edges, and compressed images look harsh. Reduce contrast or adjust highlights and shadows separately.
Gamma is useful when midtones need movement while you want less change at the extreme black and white points. It can help faces or document scans, but always review the full tonal range because the exact result depends on the image and browser rendering.
No. If the source pixels contain no usable variation because they were clipped during capture or a previous edit, a tonal adjustment can only make the flat area lighter or darker; it cannot recreate missing texture.
Vibrance is often a gentler first choice because it is intended to emphasize less-saturated colors, while saturation pushes the overall color intensity. Check skin tones, brand colors, and already-bright objects before exporting.
The controls create a new downloadable result in the browser. Keep the original file and compare it with the export, especially if you plan further editing or need a reliable master copy.
