Hi list,

I am a bit stumped. I've taken a few pictures of a snowy landscape with enough overlap and from a single point in space. The control point generation works well, everything is in focus, but the output contains single images that, for lack of a better description seem to contain a newly added gradient towards dark and then a sharp edge where they end.

I have assembled an example here. It contains the raw input and the output. You can see what I mean in "village.jpg" in the second and fourth quarter from the left.

I don't even have an idea where to start with this. Any help would be appreciated.

Harald

Hi Harald, this is a bug in enblend (which is used to join the individual remapped images). The workaround is to either use the built-in Hugin blender instead of enblend, or rearrange the order of photos in the project (drag them up and down in the photos tab) - Bruno

Hi Bruno,

thank you - I only tried the first option because it succeeded immediately. Using internal blending fixed the output. Thank you!

Harald
