HDR (High Dynamic Range) photography combines multiple exposures to capture the full range of light in a scene — from deep shadow detail to bright highlight detail. An HDR-style filter applies this dramatic, high-detail look to a single image.
What Does HDR Look Like?
True HDR images are characterised by visible detail in both the darkest and brightest parts of the image simultaneously, high local contrast (each area looks crisp), rich, saturated colours, and sometimes a slightly surreal, over-processed quality. The HDR look ranges from subtle (natural-looking) to extreme (obviously processed).
How to Add HDR Effect Online Free
Upload your photo to imgresizr.com. Open the Enhance or Filters tool. Select "HDR" or manually simulate it: increase Clarity/Local Contrast significantly (+30 to +60), boost Saturation, increase Contrast, and use the Shadows and Highlights sliders to pull detail out of both extremes. The goal is visible detail everywhere with high local contrast.
HDR Intensity Guide
| Style | Clarity | Saturation | Look |
|---|---|---|---|
| Subtle HDR | +20 | +10 | Natural, just detailed |
| Standard HDR | +40 | +25 | Rich, dramatic |
| Extreme HDR | +70 | +50 | Surreal, painted look |
HDR Best Subjects
- Architecture and cityscapes — brings out texture and detail in buildings
- Landscapes — sky detail and foreground detail simultaneously
- Interior photography — balances bright windows with dark room interior
- Cars — metallic surfaces and reflections look dramatic
- Avoid for portraits — the HDR look is unflattering on skin
