Create sepia image in ImageMagik

I am looking for some code to create sepia images using ImageMagick. I currently am using the following code, but it is producing more of a yellow image than a good looking sepia image: $command = "{$imagemagickdir}/convert -colorize '00/10/25' '{$categoryDir}/black_med_{$photo->productId}.jpg' '{$categoryDir}/sepia_med_{$photo->productId}.jpg'"; exec($command); The code above is creating the image from a black and white image, but if creating sepia from a colored image is easier, that will also work. I'm going to be kind of picky about the color of th esepia images that are created because I have been dealing with lousy sepia images for too long. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
