HDR stands for High Dynamic Range... a technical term which means in essence, better photos.  Many people claim to do HDR but produce images that are oversaturated, with a dirty look to walls and ceilings.  My workflow produces HDR images which are cleaner and more natural looking.  You'll see more detail in dark areas, highlights will not be overexposed, views can be seen through windows.  Call me to learn how HDR can help your marketing.
