[LUG] Photo management- JPEG attributes

 

I went to Poland a couple of weeks ago and volunteered to compile, sort 
out and distribute everyones photos. I am now the proud owner of about 
3Gb of them, plus 2Gb of videos, taken with several different cameras 
which I have to sort out.

Gwenview is amazing, but since very few people with have it I need to 
sort them out so that they can be viewed sanely with anything.

I have a couple of problems:

1. The collection has been taken by about 7 different cameras at various 
times. Since the actual file creation and modification times are going 
to be wrong (due to copying them around), I need to get at the JPEG time 
stamp (I am seriously hoping everyone had their clocks set right). I 
cannot find any command line programs which will give me the JPEG 
attributes- anyone know of any?

2. Several of the cameras know which way up they are when they take the 
photo. It seems that they save this as a JPEG attribute and leave the 
picture alone. The konqueror photo viewer and gwenview read this and 
display the photo the right way up, but firefox and other programs do 
not. Using the rotate tools in the konqueror photo manager I can rotate 
90 degrees in one direction and then rotate back and the image itself is 
rotated and the problem is solved, but to do that for several hundred 
photos manually is silly (this will hopefully be solved at the same time 
as 1).

Ideas anyone?

Thanks
Simon
