posted a great article by Hyperfocal Design founder Jay Weston on how to spot duff HDRIs – and how to fix them when you do.

Weston, who speaks with the experience of someone who photographs these things for a living, notes that many HDRI files are barely higher than standard LDR images in terms of dynamic range.
