I'm trying to follow this workflow.

Ok, I managed to do that with "autopano_old", I suppose it is suitable  
for the job. Anyway, I got a lot of matching points.

Done it ...

Does the preview modify the final result ?

Done it too. But I've some points with log distance (about 75 to 100)  
which are visually good. And probably necessary because without this  
point, I have nothing in some areas.

Ok

A nice loop ;-)

Done

Done

Done. Is there a rule for low - medium - long ?
I'm sure 0?xx or 1.xx, 2.xx are low. But is 40 medium or long ?

Here I've a problem with hugin.

I have a subdirectory pf my home directory called photos_300d
I have in it a suvdirectory called pano where I put the pictures I'm  
working it, the .pto file and the output from hugin.

1 - If I enter JPG for the image choice
it asks me the name in the pano subdirectory.
I enter pano.jpg
As a final result, I get a pano.jpg empty file and a pano.JPG  
(uppercase) with the striched result.

2 - If I enter multi TIFF
it iasks me for a name
I enter pano without an extension
as the final result I gent an empty pano file and *in my home  
directory* a file called photos_300D.TIFF which contains a picture with  
the right image, there is room (transparent) at the left where the  
middle and left images are supposed to be. I never got the 3 TIFF  
images I expected to have.

> 11) enblend the multi tiffs

Well, dur to the previous problem I didnt try it ...
