Hi, me again.

Sorry to start a new thread but the previous one is getting a bit
long, and I though this new question might get lost in the mist...

So, I've had a play with Autostitch, Hugin and Pandora for GIMP.
Didn't have much joy with Pandora, couldn't really work out how to
use it within the GIMP interface, but GIMP runs slowly on my
computer anyway, so it would probably have been a bit laborious
trying to use that.
Autostitch is excellent! Not sure how it works, but obviously
written by someone very clever...

Hugin is also pretty neat, though it requires a lot more effort. I
had quite encouraging success playing with it last night. The series
of photos were a bit rough and ready, and I didn't take any care to
ensure they were all taken from exactly the same point so there was
a fair bit of parallax difference between the images. It kind of
worked though, and I now have a lovely 180 degrees panarama of my
living room... :-)
Question on Hugin though, can it handle more than one row of photos,
that is can it stitch a BLOCK of pictures together, say a 4x3 block
or will it only do single height 'strips' of pictures (1x2, 1x3, 1x4
etc.). The reason I ask is that the interface only seems to let you
set control points between a picture and one other picture. To
stitch 2 dimentional blocks of photos, you'd need to be able to set
control points between a picture and up to four others...


You can set up points between any pair of images, they are just
displayed side by side. By the way, did you install autosift? It
automatically puts control points when you load the images, and this
saves an enormous amount of time (many times you don't have to do
anything except select optimize and stitch).

Sorry, Hate this laptop. There's a touchpad at the front of the keyboard,
and if your not careful, you brush your hand against it and it does a mouse
click and sends your frikkin message before you've finished writing it...

As I was saying. I didn't explicitly install autosift, but something made an
attempt to add some control points, but didn't do very well- probably
because as I said earlier, my pictures didn't line up nicely. (think it said
something about autopano???)
Is Autosift better or the same thing as Autopano?

Understand about lining up 'matrices' now, thanks (and to Daniel). Am
hopefully doing a walk at the weekend, so if I get the chance, I'll try and
take a set of photos and see if I can stick them all together!
I'll throw the same set at Autostitch, and see who can do the best job :-)
