With ExifTool, here is how I use it :

I have a .bat file that contains the following two lines :

exiftool -T -r -@ tags_sorted.txt -ext cr2 -ext jpg -ext crw f:\photos\originals\* >all.txt
copy tags_titles_sorted.txt+all.txt All_out.txt


The "-ext ..." are all related to an extension.
I have files in JPEG (.JPG) and raw from a 1DII (.CR2) and 10D (.CRW), so you have the 3 extensions here... Adapt to your needs...

In the file "tags_sorted.txt", I've put the list of tags I want to use like :
-ISO
-FocalLength
-LensType (or -Lens if LensType doen'st work)
...
(See full list of tags in Exiftool doc).

And then, in "tags_titles_sorted.txt", you have a list of the tag names (without '-'), tab delimited.
Here it would be
ISO FocalLength LensType

At the end, you get a file "All_Out.txt", which is a tab-delimited file with all your required data.
I then import it in an Access Database for easy query and analysis...

I've done it for 47000 pictures. It works.

Good work...


I hope it is of some help...
