InDesign has this nice feature where you can place a PSD file and then turn off layers as you please.
The function is called "Object Layer Options"
This makes you able to have multiple "states" of the PSD - but only saved inside InDesign,
not the actual PSD file.
This function i often use for inserting multiple images from ONE file.
If i make 10 duplicates of the same comp I can enter each and turn off layers instead
of having to make 10 copies of the same one.
So visible layers should be unique for each duplication of the same comp.
Fell free to ask me for details 🙂
