Original 'normal exposure' image:
HDR Image (Tone Compressor):
HDR Image (Detail Enhancer):
There are tons of tweaks with both Tone Compressor and Detail Enhancer so you can make each one look radically different. For these landscape shots both HDR options look much richer than the original normal exposure. The Detail Enhancer is more surreal and obviously not a traditional photograph where I think the Tone Compressor done right could look like a traditional picture (just with more dynamic range than normally seen).
