Convert a lot of .tif files using imagemagick's mogrify command

Question

I have a lot of tif images in a directory. So I try to convert them into jpg format.

I use this command : mogrify -format jpg *.tif

But I get an error... an error for each image in fact:

mogrify: 2281.tif: unknown field with tag 37724 (0x935c) encountered. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/746.

Maybe I am doing something wrong... Does anyone have an idea?

@Sardathrion i don't see how that's going to be useful to the OP. not saying you might not have a point, but i really don't get what you're talking about. mogrify *is* convert, just different syntax. consider adding more information to your comment? — ixtmixilix, Jan 20 '12 at 14:44
`convert` (convert and modify images) vs `mogrify` (in-place batch processing) from the documentation. I always used mogrify to change things in the images and convert to change the size/format. Mogrify can be dangerous and lead to strangeness as described here: http://www.imagemagick.org/Usage/basics/#mogrify. Sure, you can use mogrify and that's not a real answer the the question, thus a mere comment. — Sardathrion - against SE abuse, Jan 20 '12 at 15:06

This is an informational error, are you sure that the file has been not converted?

That tag marks private information about the image for Adobe Photoshop. Try flattening the image before exporting/saving.
