I ran across this video today and I can't help but comment on the issue of "dirty whites" in HDR processing. The shots in this video are a great illustration of the issue of "dirty whites" that real estate photographers run into. Notice how the whites and other lighter colors in most of the interior shots have areas of "dirtyness". Kind of like there is smoke damage on the walls.
Some photographers apparently don't see this or believe that it's an issue that is out weighed by the increased dynamic range benefits of HDR. I find it hard to ignore.
This problem is exactly what Trey Ratcliff is talking about in his E-Book on the Top 10 Mistakes in HDR Processing. This is one of the classic problems that arise in HDR processing and Trey points out that this dirtiness can't be remedied with sliders. Trey suggests a couple of solutions to this problem:
Yes, this all works great if you are doing fine art and aren't pressed for time. But if you are shooting three or four homes a day and are committed to deliver photos in 12 to 24 hours you have a problem on your hands. This problem is exactly why most real estate photographers that are shooting brackets are moving to Exposure Fusion or using multiple small speedlights instead of HDR. Most real estate photographers find that getting great results with HDR requires a huge amount of time in Photoshop to fix issues like "dirty whites" and this extensive amount of postprocessing time eventually limits the number of shoots you can do per day and means you have to spend an extensive amount of time at a computer doing post processing.
The bottom line is to take a look at either learning to use multiple speedlights or checkout Exposure Fusion with a just a few speedlights. EF and speedlights can give you a much better look with a lot less time invested than HDR processing.
