These shots are beautiful!

You will probably find that your images store better as PNGs due to the large areas of constant colour.  The quality will also be nicer too, but that does not seem to be a problem with the shots you have shown us.  *starts drewling again*

Also, by memory ImageMagick allows you to chain various transformations into one line:


--- Code: ---mogrify -crop ${crop_w}x${crop_h}+${crop_x}+${crop_y} -fuzz 30% -trim -background black -resize 640x512\! ${1%.jpg}-color.jpg
--- End code ---
