This does nothing to increase the dynamic range. Oversaturated
highlights and underexposed shadows will remain exactly the same.

At the very best, this method could be called pseudo-hdr. In actuality,
it is pure malarkey.

For a single exposure pseudo-HDR, single exposure tone-mapping using a
piece of software such as NIK HDR Efex Pro to tone-map the single
exposure, rather than making the RAW ACR adjustments, would result in a
far more satisfying result.

My suggestion would be to download the demo copy of NIK HDR Efex Pro
and see for yourself.
