Jasper's DRIMaker is a tiny application with which you will be able to automatically produce DRI images. This application does not produce 32-bit HDR-images which will be changed to LDR via tone-mapping but uses the so called Exposure Blending in order to crossfade each image iteratively.
So in the end, the manual technique that people do in e.g. Photoshop, is simulated.
You will find more information about this kind of technique on this page. Everything you need is an exposure sequence in JPEG/TIFF format.

It's hard to believe that over two years have passed since Aperture's launch. It seems like only yesterday that I was fielding e-mails from livid zealots and supportive professional photographers regarding my less-than-glowing review of the buggy, unfinished mess that was Aperture 1.0 (and see our follow-up look at Aperture 1.1). But much has changed in those two years, including a price drop from $500 to $200 to compete with Adobe's Lightroom. By version 1.5, most of the problems, missing features, and RAW quality issues were addressed.
