Date/time Setup:
Set this, you'll thank yourself in post later.
Copyright Info:
Fill in details.
Format:
Format cards – Format cards every time before you start shooting.
File Number:
Set the file numbering or reset it. Failure to do this means you get the same
file names corresponding to different shoots on different days. Create a
system before shooting with a number or something that can immediately be
recognised as a different day or location by an alpha-numeric sequence.
Again, you will thank yourself later.
Set File Name:
Name the files according to the scene.
Setup6:
Rec. Media Settings:
You can control the way the camera records to both cards in this menu. Whether to
duplicate, JPGs on to card1, RAW on Card 2, Movies card 1, RAW + JPGS card 2, etc.
Otherwise set to standard turn on Auto Switch Media to jump to the next card once the first
card is full.
Setup7:
Setting Reset:
Good idea to perform so you know exactly how the camera is setup. You do not know what
the last user has done to the settings.
My Menu Setting:
Allows you to add the menu items you use most to your own menu for quick access.
