saving multiple .cr2 files as .jpg files

I’m wanting to save multiple .cr2 files as .jpg files. Is it possible to do that using the command line?

At the moment I’m using:

convert IMG_7119.CR2 1.jpg but there must be a way to do this for a whole folder at once!

Re: saving multiple .cr2 files as .jpg files

you just want to rename them from cr2 to .jpg?

navigate to the directory where you have them all.

that will keep existing filenames, but change the extension. blabla555.cr2 will become blabla555.jpg.

and if you want to undo that:

EDIT: ah, just googled .cr2. it may not be as simple as i make it out to be above, but it may be worth trying first, in case it is. the directions to undo the experiment are there if it fails. i did find this link: http://marc.merlins.org/linux/techno. raw_jhead.html

Re: saving multiple .cr2 files as .jpg files

The following commmand will do what you want. It retains the original files and creates new JPG images with the same base name but with the jpg extension. As a precaution, use some test files initially to insure that it works as you want.

I assume that the conversion from CR2 to JPG has worked for you before.

It has worked before, but I just forgot how it works.

I tried what you said kaibob but it doesn’t seem to work

None of the files are changing to be jpegs and it seems to be «stuck» on a blank line in the terminal.

I must be doing something really stupid wrong.

I still can’t get this to work

I’ve also found this script on my travels, but I don’t know how to use it, or if it is what I want to do!

Thanks!

I still haven’t had any luck

Re: saving multiple .cr2 files as .jpg files

I still haven’t got any alternatives to work.

I’ve tried my old method today (convert IMG_7119.CR2 1.jpg) and it didn’t work

This is the error that I got.

Re: saving multiple .cr2 files as .jpg files

I got this working, using Ubuntu 10.04 LTS x64.

Re: saving multiple .cr2 files as .jpg files

In case someone wants to use imagemagick as in the original request.

I still haven’t got any alternatives to work.
