HDR (High Dynamic Range) photography captures detail across the full range of shadows and highlights in a high-contrast scene — from dark interiors to bright windows, or from shadowed valleys to sunlit peaks. While dedicated HDR software exists, you can achieve excellent results editing HDR-style photos online for free at imgresizr.com.
What Is HDR Photography?
HDR photos are created by merging multiple exposures of the same scene — one bright, one dark, one in between — to reveal detail in both highlights and shadows that a single exposure cannot capture. The result is a photo where nothing is blown out or lost in darkness. If you have a single well-exposed shot, the Enhance tool can simulate HDR tone-mapping to bring out shadow and highlight detail.
How to Edit HDR Photos at imgresizr.com
Upload your HDR photo to imgresizr.com. Use the Enhance tool to fine-tune the tone map — the goal is balanced exposure where both shadows and highlights show detail. Boost contrast moderately to separate tonal ranges. Increase saturation if colours look muted. For HDR architectural shots, the Sharpen tool reveals building texture and window detail effectively. Use the Crop tool to compose to a 16:9 widescreen ratio, which suits the dramatic wide-angle nature of most HDR scenes. Compress to under 2MB for web use — HDR photos tend to be large files.
HDR Photo Characteristics
| Feature | Goal | Tool |
|---|---|---|
| Shadow detail | Bright enough to see | Enhance brightness |
| Highlight detail | Not blown out | Reduce overexposure |
| Colour vibrancy | Rich but natural | Saturation in Enhance |
| Edge sharpness | Crisp architecture | Sharpen tool |
HDR Editing Tips
- Subtle HDR looks more professional than the over-processed "halos" of early HDR style
- Real estate and architectural photography benefits most from HDR treatment
- Landscape HDR should look dramatic, not cartoonish — keep colours natural
- Compress HDR files carefully — the extra tonal detail increases file size significantly
