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.
My AIM in this implementation is to Get the most natural results, as i Think that for photographers the whole DRI thing is made to compensate the bad dynamic range of digital sensors. If the final image has a greater dynamic range than the human eyes could normally adapt to, you have gone much too far imho.
