John, These are not errors, but just warnings (as it is stated in the message itself!). I am not sure why you got the first message. What is libtiff version installed on your system? The second one is just a signal that the file contains field that is not known to libtiff and can not be interpreted. > The split I was trying to accomplish (separating layers from a > Photoshop TIF file) does not work. The file works fine in Photoshop. Whay do you think you can split the layered TIFF file from Photoshop? I don't know how the information about layers is stored in a TIFF file and I am not sure that ImageMagick can work with that info. > P.S.
