Enfuse processing is very widely used in interior real estate work these days (about half of all real estate photographers). Enfuse refers to Exposure Fusion which is an alternative bracketing processing technique to HDR. The most popular implementations of Exposure Fusion are LR/Enfuse and Photomatix (sometimes referred to as blending).
Because LR/Enfuse and Photomatix both have Lightroom plugins, Lightroom is a very handy way to process your bracketed shots. On his SiMax Channel Simon shows the basic processing in this previous video and in this video Simon shows you how to decide which brackets to process and then how to some final touch up to the Enfused result in Lightroom.
Of course Simon does not explain how to get the set of bracketed photos that he's using and I know that question will come up so here are some of popular ways of shooting brackets:
Stay tuned to the SiMax Channel for an up coming video on mixing flash with Enfuse processing.
Update May 27: Simon just pointed out that he's added another tutorial that describes how he uses the colour labelling feature in Lightroom to track where he is in post processing a shoot.
