Dear colleagues: A couple of questions I was hoping you would be able to help me with. 1. I remember a discussion at one of the newsgroups about the possibility to connect a portable GPS unit to a Nikon D2X so that the GPS information would be embedded in every image. Is there such an option for making the same work on a Canon EOS 1Ds Mark II ? Is there a way to connect a portable GPS unit to the camera and capture GPS data ? 2. I've tried to view the metadata of image files created by my camera but have had no success. I had originally tried to use a regular text editor but was seeing anything intelligible. After speaking with someone who has more experience I was told that I should try a hex editor instead since the image is all stored in hexadecimal format. Do any of you know of a good hexadecimal editor or reader for Mac OS X that would be able to read the hex information contained in raw files and allow me access to it ? In case you know of other software outside of hex editors that will do the same I would appreciate the suggestion. Any information and suggestions on software as well as hardware will be greatly appreciated. Thank you in advance. Best regards, Joseph --- Dr. Joseph Chamberlain Oral and Maxillofacial Surgery
