This command-line software is a freeware utility that merges multiple exposures of a scene through bracketed exposures.
What sets Bracketeer apart from other similar tools is that it's very similar to tonemapping with an HDR image, with the added benefit of no HDR image ever being created, resulting in zero ghosting. The software is very versatile, and as it can work with any type of bracketed image set, it's not limited to panoramic equirectangular images, making it useful for a broad range of applications.
If you already own PanoPreviewer, the good news is that you get Bracketeer free of charge. By entering your PanoPreviewer serial number, you can activate the full version of Bracketeer and take advantage of all the benefits it brings. Otherwise, you can still use the demo mode while you decide if you're ready to purchase a serial number.
