A few years ago I had the good fortune of learning about Unified Color HDR (high dynamic range) softwares, while surfing the web for HDR softwares in the market. I downloaded the free fully functional 30 day trial of HDR Express and HDR Expose and evaluated the software with a number of my bracketed exposures which had previously posed a challenge for me with other softwares that I used. I was so impressed with the results that I purchased the software shortly after.
