Remarkably simple. Probably because I was only stitching two photos. |
29 |
|
30 |
1): Emerge hugin. Current stable version is 2011.0.0, and that worked fine. |
31 |
|
32 |
2) Launch hugin |
33 |
|
34 |
3) Hugin defaults to leaving the wizard tab open. Load your source |
35 |
images (brum-3068.jpg, brum-3070.jpg). |
36 |
|
37 |
Because the files don't have EXIF data provided by the camera, you'll |
38 |
need to provide some key details about the lens used for the original |
39 |
pictures. I ventured a guess of 50mm, as that's the same as my prime |
40 |
lens, it's around the upper end of current kit lenses, and it's around |
41 |
the lower end of basic macro zoom lenses. It happened to work fine. |
42 |
|
43 |
4) Click the "Align" button. Hugin will use its wizard to discover |
44 |
control points and optimize them. |
45 |
|
46 |
5) Hugin will have popped open the fast preview window. As long as it |
47 |
looks somewhat fine, go back to the main Hugin window and click on the |
48 |
Stitcher tab.[1] Enable exposure-corrected, low dynamic range. Keep |
49 |
everything else disabled. Set your format and quality settings to |
50 |
taste. |
51 |
|
52 |
6) Click "Stitch Now". Hugin will put the panorama image in the same |
53 |
directory as your source images. |
54 |
|
55 |
I'll email you the stitched-together file off-list. |
56 |
|
57 |
Outside the emerge, this whole process took less time on an Intel |
58 |
Pentium B940 than writing this email. |

[1] I probably could have clicked the 'Create Panorama' button in the |
61 |
wizard tab, but I fell back to habits. |
