If a Picture Style has already been registered under [User Def. *],
changing the base Picture Style in step 5 will nullify the parameter
settings of the registered Picture Style.
If you execute [Clear all camera settings] (p.70), all the [User Def. *]
settings will revert to their defaults. Any Picture Style registered via EOS
Utility (EOS software) will have only its modified parameters reverted to
the default setting.
To shoot with the Picture Style you adjusted, select the registered [User
Def. *], then shoot.
Regarding the procedure to register a Picture Style file to the camera,
refer to the EOS Utility Instruction Manual (p.536).
