For the 3D work, I've been using the for-pay Photoscan application, which works great for me, especially now that I upgraded my laptop to 16GB of RAM. (I'd like to use a freeware option, like VisualSFM, but I can't get it to run yet on my MacBook Pro. I'm working on it now that there's a new installer on GitHub.) The PAP work needs some stitching to create photomosiacs. For that I'm using the freeware Hugin, which is very powerful, but not tremendously well documented, so there's a bit of a learning curve partly due to adapting the old tutorials to the newer versions with their nicer interface.
I already got one photomosaic done during the campaign this summer, just to make sure it was going to work. Here's a small version of the photo. You can catch my feet in more than one place:
|Big inscription from the Roman theater at Ostia Antica.|
|Same inscription corrected.|
Following the tutorial, I was able to create a "corrected" version in under half an hour. I used MorphX to create a short video that morphs the original into the final version.
All in all, I'm pretty pleased with the outcome and looking forward to using Hugin with my existing photo collection.
PS In the first version, I incorrectly linked to the "Simulating an architectural projection" tutorial, which is similar, but doesn't include the horizontal correction.
