Is this due to an uncompatible mono package in breezy?
Or is this because of a bug in autopanog?

Kind regards

Getting EXIF data from coolpix 950 jpgs using hugin

Hello,

I have just recently discovered and started using the following tools to create
panoramas:  autopano-sift, hugin, panotools (PTStitcher), and enblend.

I have an old Nikon Coolpix 950 camera, and I have been unable to automagically
read the lens settings using the "load EXIF" feature of hugin.  When I click on
an image in hugin and pick "load EXIF", it then brings up a box asking me for
the focal length.  I've been putting this in manually for now and it works
good, but I'm curious as to why it isn't able to get the info from the EXIF
info in the jpgs?

Is the coolpix 950 too old to provide the info that hugin is looking for?  As
far as I know, the 950 does save EXIF info to the images, as that is the info
that I'm using currently to manually type in the focal length..

any suggestions, ideas, etc appreciated!

thx!

Hugin also needs information about the pixel size, because without it,
the focal length is meaningless.

Some camera do not save both in the EXIF data. Can you email me a
example image privately?

Initial Comment:
When you open help - you cannot follow the instructions
in the application at the same time as viewing the help
page- I think that this is a usability issue. 

It would be good to be able to do work whilst viewing
the help file rather than trying to memorise stuff and
then do it.

Otherwise - keep up the goo dwork guys, it is appreciated.

Re: Getting EXIF data from coolpix 950 jpgs using hugin

Crop factor is the size of the CCD x A number to give 24mm x 36mm. 
Everything is still calculated relative to 35mm camera lens focal 
lengths in relation to 35mm film dimensions which are 24mm x 36mm.

Grab the CCD sensor size from your manual, determine what it needs to be 
multiplied by to give 24mm x 36mm and you've got your crop factor. You 
may not need this IF the exif tags are already giving effective focal 
length equivalents relative to 35mm film dimensions. I don't know much 
about exif tags so this last part may be totally wrong, but you should 
at least be able to understand the principles to know if I am.

Re: Getting EXIF data from coolpix 950 jpgs using hugin

Forgot to mention, crop factor is un-changing, not based on F-Stop, 
focal length or anything else that is variable

The crop factor for your camera should be 5.48.  (Its the ratio of the
35 mm Film diagonal and the diagonal of the CCD chip in your camera).

Unfortunately this information is not stored in the EXIF information of
your camera, so you have to enter it by hand.
