Hi,
I have been using the 2014 release of Hugin for a while, and have noticed some artefacts appearing in shadows of exposure-fused images. I have searched high and low and have found only one similar post (from 2011), but have not found any fixes for this issue, or any current discussions of this topic. https://bugs.launchpad.net/enblend/+bug/787387 <https://www.google.com/url?q=https%3A%2F%2Fbugs.launchpad.net%2Fenblend%2F%2Bbug%2F787387&sa=D&sntz=1&usg=AFQjCNE9uRQ35tBWYDs6vE7qxIu-hO-JrQ> I noticed this first when attempting some pseudo-HDR merges from single RAW files (3 to 5 images with different exposure compensation, converted to 16 bit tiffs in Capture NX). Brightly coloured pixels (mainly shades of green, magenta, cyan and blue, sometimes white) would be lurking in shadowy areas of the stacked or stitched final images. These are generally worse when using "exclude masks", but can also appear in images where no masks were used. These brightly coloured "random" pixels appear in dark areas of the fused image stacks and also stitched panoramas. They have appeared in many different projects. I have just checked some panoramas made earlier this year, which must have been made with the older (2013?) Hugin version, and there are no artefacts in those images. You need to be zoomed in 100% plus to see them. These pixels can be selected and replaced (i.e., with black) in an image editing software, but because they are not exactly the same colours it takes a long time to manually select all the erroneous pixels - even with a moderate tolerance threshold set – so not an ideal solution. Just wondering if anyone else has noticed this and is there is any way around this issue? Dougal.
