Expert Tips

What the pros know

Best For

A quick look at an HDR image or environment map without 3D or photo software.

Previewing an HDR file in a browser

Radiance HDR files hold far more brightness range than a normal screen image, and browsers can't open them. We convert the HDR to a standard PNG and place it in the HTML page. That gives you a quick preview, but the extra brightness range doesn't survive: a PNG is a normal image, so very bright and very dark areas are flattened to what a regular screen shows. HDR to HTML used to fail; it works now.
