sorry,
but it's unbelievable!
i'm surfing always with opera or sometimes with firefox. both browsers are not able to show this single line:
"Auto CHDK to EXIF v1.2.zip (202.03 KB - runtergeladen 53 Mal.)" theres really nothing - blanks ...
i had to use IE6.0  >:(  for finding this. why is it only possible by this ugly browser and not by the other ones?
thank you, wontolla, for helping me a bit to find it.

At least firefox is (I suppose every browser is, there's nothing special about the link).

The purpose of this post has been superseded.  It was intended as search engine fodder for this thread as the string "CHDK2EXIF", which people were being directed to find, did not exist in this thread.

Barney Fife has created an excelent summary of the information for which you may be searching.

Barney, your new topic reminded me I once started to write a shell script (exiftool runs fine on Linux) to do the same things your utility does. From your posts about your version 1.1 I figured it would have to do at least this:

Code: [Select]
  exiftool -overwrite_original_in_place '-EXIF:ExposureTime<MakerNotes:ExposureTime' $1
  exiftool -overwrite_original_in_place '-EXIF:FNumber<MakerNotes:FNumber' $1
  exiftool -overwrite_original_in_place '-EXIF:ISO<composite:iso' $1
  exiftool -overwrite_original_in_place '-MakerNotes:CameraISO<composite:iso' $1

(Replace $1 with a file name and I believe the above should work in Windows command prompt as well). I think these four commands will do this:

Override ISO to useful EXIF:ISO
Override Shutter Speed to useful EXIF:ExposureTime
Override FNumber to useful EXIF:FNumber

Would you mind verifying this and giving a hint what your program feeds to exiftool in order to do the other things?:

A hidden subject distance to a useful EXIF:SubjectDistance and EXIF:UserComment (keep in mind the value is in meters)
Canon OwnerName to EXIF:Artist

That shows the exact EXIF fields that are being copied from > to:
-composite:iso>EXIF:ISO
-composite:iso>MakerNotes:CameraISO
-MakerNotes:ExposureTime>EXIF:ExposureTime
-MakerNotes:FNumber>EXIF:FNumber
-MakerNotes:OwnerName>EXIF:Artist
-MakerNotes:FocusDistanceUpper>EXIF:SubjectDistance
-MakerNotes:FocusDistanceUpper>EXIF:UserComment


Thank you, this helped a lot :)

Originally I was hoping I could make a utility that would not only correct all ISO fields, but also allow other features. Like a quick FAT16/32 format SD card choice, Make SD Bootable, Format with CHDK Backup (it would read all CHDK folders, save them, format the SD card, and put your CHDK back like it should be).

Like a little CHDK Swiss-Army knife utlity. Doing all those little maintenance things that are CHDK related. If you work on this, could you consider adding those features? Ideally, an all-in-one DNG4PS utility would be best of all. Having everything in one CHDK tool. Maybe even convert DataGhost's Text2Grid utility to add into it too. Heck, throw in a syntax highlighting and syntax checking uBASIC editor too. :)

Now you're getting carried away again :D  I think I'll do the CHDK-preserving-format one one day, though, it's a good idea. But this is all for Linux (and compatible) command line use, I prefer that (and I'm really not a coder either, anything with a GUI means a lot of work for me).
