What Is HDR?
HDR stands for High Dynamic Range. In photography, "dynamic range" refers to the range of light levels from the darkest shadows to the brightest highlights in a single scene. Standard photography often struggles to capture this full range—leading to "blown-out" highlights (too white) or "crushed" shadows (too black).
HDR imaging solves this by combining multiple exposures of the same scene into one single image. This process ensures that detail is preserved across the entire spectrum of light, resulting in a more balanced, realistic, and visually rich result.
Why It Matters for Archiving
When archiving spaces, especially in architecture, art galleries, or heritage sites, lighting can be incredibly complex. Large windows, dim corners, and reflective surfaces all present challenges. Standard photography would lose detail in these areas, but HDR ensures that every texture, color, and subtle nuance is documented.
For a digital archive, accuracy is everything. HDR provides a level of fidelity that standard imaging simply cannot match, ensuring that the archived record is as close to the real experience as possible.
The A360 Approach to HDR
We don’t just use "auto-HDR" features. Our team uses exposure bracketing on professional DSLRs, capturing specialized RAW data. These exposures are then manually merged and toned to avoid the "artificial" look often associated with low-quality HDR. The result is a clean, natural, and highly detailed visual that is perfect for immersive tours and permanent records.
