EasyHDR BASIC is a HDR (High Dynamic Range) image processing software. It's a freeware version based on one of older easyHDR versions: 2.13. As compared to the full version it lacks few options like i.e. batch processing or alignment, but apart from this it allows full HDR processing capabilities.
With easyHDR BASIC get photos without underexposures and overexposures. What you need to do is to take a series of variously exposed photos (preferably using Auto Exposure Bracketing), load them and tone map with easyHDR BASIC. You can get either realistic or dramatic look.
Easy to use, freeware HDR processing software. Gives more flexibility than other software as you can go back and regenerate HDR without reloading photos. Some post-processing filters are also available.
