Review : Hydra HDR Creator
Photography blog (and sister site to TotalApps) Seven by Five have a great review of Hydra the latest in High Dynamic Range Photography creator. Hydra is available as a plugin for Aperture, Lightroom and as a stand alone app.

This is why often in cameras when shooting directly into the sunlight either our family is well lit, and the background is completely white, or our backgrounds are relatively well lit with detail, and our subjects are often obscured in darkness.
