Thor Larsen commented on Gary Mortimer's blog post No hiding behind AC 91-57 anymore
"RocketMan, I am totally on-board with what you are saying and can't help but agree. Having been involved in modeling now for several decades I also have a feel for the issue at hand.  That issue is primarily: What was once a hobby that required time…"

"A great program, one I have used a lot is called autostitch: http://cvlab.epfl.ch/~brown/autostitch/autostitch.html
The interface is a little quirky, but the results are beyond the pale. Will stitch a folder of images without any reordering…"
