Hi all!
It have been long I didn't read the list because the large amount of emails and the little
time I have.
I've been reading that in the last year lots of people where interested in the timelapse
panorama and the video panorama possibilities. Also I'm very interested as I work on the
audiovisual world, I do cultural audiovisuals for museums and expositions.
I would like to explain you the project I'm immersed in actually and how I'm doing it,
maybe you can tell me any advice on the workflow.
The project is for a temporal exposition about Andalusia, a part of Spain. On a part of the
exposition will be two half circles covering the 360 vision around the spectator where we
will project (with eight video projectors) a timelapse panorama of the whole day in three
places.
The technical part:
3 locations (3 days of shooting)
Canon 350D, 10-22mm lens using 10mm
Photos each 60 degree, with the panosaurus head (not in a fix place each photo) 6 photos
each round
(manual focus, manual exposition, shooting in RAW, auto white balance)
Photos each 5 minutes from 7:30 to 20:00
Photos per day: 700-1000
I import all of them on Lightroom, I stack each round and color correct each first photo of
each round.
Once I have every first photo corrected, I sync the color of the first photo of the round to
the other 5.
Then I export to jpeg and import ALL to ptgui.
When all are loaded (takes lots of time) I click on align and the app start thinking.
After it have searched the control points it gives me a good result depending on the place
at a general view, but when you look close-up the stitching errors are big enough to not
be able to use it in video directly.
The two things I would improve on ptgui would be:
1- to be able to look for points between consecutive images only, because actually it looks
for points all arround and very little times are located on consecutive images. (I'm running
a test on lowering the points between each pair images and higering considerably the
amount of points in the whole project)
2- to be able to limit the zone where ptgui looks for points, for example 10 or 20 degrees
arround the horizon would be great. Like that I would be able to avoid some problematic
zones.
Then with all the results I will have to make a postproduction work to make fades between
them, and to expand the images to one frame per second.
Also over the panorama will appear a sketchbook with drawings of animals and trees, and
a voice will act as a naturist observing the landscape.

I hope you like it and enjoy the theme.
I would greatly appreciate any advice as I'm not getting the good results I hoped.
Thanks a lot!
