I\u2019ve been playing around with Qtpfsgui<\/a>, the freeware HDR generator. I\u2019ve tried Photomatix but didn\u2019t care for it, plus it costs money. I\u2019m all about free and open source. Through my experimentation, I\u2019ve discovered an important revelation: 16-bit TIFF files are far, far better source images than 8-bit JPG. I was using 8-bit JPG files for my source at first, and was extremely disappointed in the results. Now that I\u2019ve moved to TIFF, I find things to be a whole lot better.
