Canon 10D backup settings
 

My dad has a 10D that is being used to photograph the inside of
human eyes (yes, with a special [Canon] attachment). Now it
would be sweet to also use this camera to snap some pictures
once in a while (on vacation for example).

However this camera has been specifically setup for working with
the attachment and has a the shutter set to 1/60 for example.

My dad though (heard it from someone else) that the camera has
multiple (user) profiles so everyone can use different settings
without upsetting others (in this case for work use and pleasure
use). However I can't find anything in the manual or on the camera
except for the custom functions which seem to be something else.

Does the camera have such a feature? If not does anyone know
of a software application on the computer (Windows) that could
achieve this (I saw there is an SDK available)? To store the
camera's current settings and restore it at a later time. That
would be really great to have!

Thanks!

Anyone?
