Version: ImageMagick 6.8.4-3 2013-03-29 Q16 http://www.imagemagick.org

/usr/local/bin/convert IMG_1170.JPG -quality 98 -gravity southeast \
-stroke white -strokewidth 1 \
-pointsize 16 \
-annotate 0 'Image Copyright ... blah blah' \
IMG_1170_a.JPG
And the outcoming image is heavily darkened.
I ran identify before:
And after:
The image is available for testing at:

I've tested several alternate grayscale photos, with the same result. The images turn out very very dark.
I'd appreciate any kind of assistance a lot as I need these photos for a project of mine.
