Not like a 'roll of film'

What was I thinking! 

Of course saying that the photograph jumble was like a roll of film was more of a muscle-memory statement than anything else.  In actual fact it could not be less like a roll of film.  The simple fact that there are colour and b&w images shows that it is much more like a 'digital flash card' than a 'roll of film'. 

Is 'digital flash card' a universal statement analogous to 'roll of film'?  I doubt it.  There's nothing to link it to photography per se.  Mind you, the same is (sort of) true of roll of film.
