How is HDR merging done?
Modern cameras can't capture the full brightness range of a real scene in a single shot. Expose for the highlights and the interior goes dark; expose for the shadows and the highlights clip. Bracketed shooting solves this: you take several frames at different exposures (typically three to five) and merge them into a single HDR image that holds detail in both.
In our online HDR editor you're able to merge your exposures and adjust the look, even choose how "compressed" or physically accurate you want your final HDR image:
Why merge RAW files instead of JPEGs?
RAW files encode 12–14 bits of data per channel, versus 8 bits in a JPEG. Merging from RAW gives you more tonal information to work with and avoids the compression artefacts and banding that accumulate when you stack already-processed files. The result is a cleaner merge with smoother gradients.
How to use this tool
- Drop your bracketed set of RAW exposures into the zone above (CR2, CR3, NEF, ARW, DNG, and more are supported).
- Click Merge and wait for the exposures to be combined (typically takes 30 seconds or so).
- The built-in HDR editor opens automatically. Adjust saturation and luminance, then export your final image from there.
