Title: small artifacts in fused 16bit TIFFs Status in Enblend: Fix Committed Bug description: When blending a set of 16bit TIFF images, I noticed artifacts in the output. Depending on the enfuse setting used, these occur in different places and look different. When I used the default setting, the artifacts looked like groups of coloured dots (see enfuse_problem_fused_default.tif) and when I used exposure only, they came as single pixels (see enfuse_problem_fused_only_exposure.tif), also see the respective jpg screenshots where the artifacts are enlarged. The images were created by hugin's nona, I tried several sizes and also the original unmodified images, the effects were the same. The 16bit TIFFs were created by digiKam's batch RAW import from Canon CR2, using conversion to 16bit and storage as TIFF as the only active processing steps. I converted the images to JPG with gimp, and when I fused the JPGs, there was no problem. I also opened the images with fotoxx and saved them in a different file but the same format, in which case the problem persisted. I suspect the problem may stem from the 16bit format. Here's my session which produced the flawed results: >enfuse enfuse_problem_[0-2].tif -o enfuse_problem_fused_default.tif enfuse: info: loading next image: enfuse_problem_0.tif 1/1 enfuse: info: loading next image: enfuse_problem_1.tif 1/1 enfuse: info: loading next image: enfuse_problem_2.tif 1/1 >enfuse enfuse_problem_[0-2].tif --saturation-weight=0 -o enfuse_problem_fused_only_exposure.tif enfuse: info: loading next image: enfuse_problem_0.tif 1/1 enfuse: info: loading next image: enfuse_problem_1.tif 1/1 enfuse: info: loading next image: enfuse_problem_2.tif 1/1 >enfuse --version enfuse 4.1-101796703d73 I use a Kubuntu 11.4 system on an intel processor.
