Public bug reported:

Here are two examples http://kvtours.com/test-photos/CraterLake.jpg
and
http://kvtours.com/test-photos/Wheeler1.jpg


http://kvtours.com/test-photos/enblendBlackEdgeErrorTest.zip That is a 8.12mb test package for use with hugin. 

The test package is an example that I just took out of a half pano that
I was working on last nightt, that I doubt many people would have cause
to do, but it was an easy one to show the problem with. In it you will
find two pictures and a pto file. One of the pictures is in the pto file
twice. The second copy has different light settings so that the sun is
not quite so blown out. There is complete overlap on those two images.
When I put a single include mask on the one that has a good sun I get a
pretty good result, but the mask goes a bit further away from the sun
than I want. So I add a second include mask to the other copy to keep
most of the good colors and then I get the results shown in the
Wheeler1.jpg

If I remove one of the include masks and instead use one include and one
exclude I get the results that I want with no bugs. Remove both masks it
works as expected as well.


On the crater lake one I did it a month ago and it more clearly shows
the problem(I did not include it as a test package as it is a large
set). My work flow on it, I was going along stitching small versions
finding places where there were masking errors or that I needed more
control points and correcting as I saw fit and then somewhere along the
lines the black started showing up. At first it was just a little bit on
the rock under the tri-pod. That caught my eye and I removed all the
masks in that area and restitched. That did not remove the problem(I
still had masks in other places.) I figured I could photoshop it so I
continued and a few masks and restitches later I had problems showing up
in places where there were and had never been a mask(that is the photo
that I attached to this post). At that point I scrapped the project and
started over and had no problems on my second try.


I have seen the bug with both the version of enblend that comes with hugin 2013 and enblend 4.1.3 win64 version. 

I am running windows 7 on a desktop. A friend has had the same problems
with windows 7 on a laptop.

For command line options I use the standard that hugin has plus I add in
-a --no-ciecam

Here is the thread where I first started talking about it.
