enfuse is a command-line program used to merge different exposures of the same scene to produce an image that looks very much like a tonemapped image (without the halos) but requires no creation of an HDR image. Therefore it is much simpler to use and allows the creation of very large multiple exposure panoramas.
enfuse is based on a paper by Tom Mertens, Jan Kautz and Frank Van Reeth. The implementationwas done by Andrew Mihal (developer of enblend) - http://research.edm.uhasselt.be/~tmertens/exposure_fusion/
enfuse is currently in beta and available with the development version of enblend.
Usage: enfuse [options] -o OUTPUT INPUTS Common options: -h Print this help message -l number Number of levels to use (1 to 29) -o filename Write output to file -v Verbose -w Blend across -180/+180 boundary --compression=COMP Set compression of the output image. Valid values for compression are: For TIFF files: LZW, DEFLATE For JPEG files: 0-100 Extended options: -b kilobytes Image cache block size (default=2MiB) -c Use CIECAM02 to blend colors -g Associated alpha hack for Gimp (ver. < 2) and Cinepaint -f WIDTHxHEIGHT+x0+y0 Manually set the size and position of the output image. Useful for cropped and shifted input TIFF images, such as those produced by Nona. -m megabytes Use this much memory before going to disk (default=1GiB) Fusion options: --wExposure Weight given to well-exposed pixels. --wContrast Weight given to high-contrast pixels (unimplemented). --wSaturation Weight given to highly-saturated pixels (unimplemented).
