HDR Photo
A photography technique that combines multiple exposures to capture scenes with extreme brightness differences without losing detail in highlights or shadows.
HDR (High Dynamic Range) photography is a technique for reproducing scenes with large brightness differences in a way that closely matches human perception. Standard single-exposure shots often result in blown-out skies or crushed shadows, but HDR compositing preserves detail across the entire tonal range.
The basic workflow involves capturing three or more bracketed exposures (under, normal, and over) and merging the best-exposed regions from each. Modern smartphones perform this process automatically. The resulting image has a wider dynamic range, retaining shadow detail and highlight gradation simultaneously.
Because HDR images contain more tonal information, file sizes tend to be larger. Using the image compression tool before web publishing helps maintain page speed. Over-processed HDR can look unnatural, so fine-tuning with a tone curve keeps results realistic.
