For the price, Pangea's Bracketeer gets the job done easily. Six images can be loaded into the main window and various views compared. Once the bracketed images are chosen, just click the Enfuse It button and Bracketeer creates a fused image that opens up in a new window.
Images need to have all adjustments made prior to loading into Bracketeer and must be in TIFF format. Bracketeer does not work with RAW files, but this is a budget program that produces good results with little effort. The results are natural looking images with little effort.
