On the more esoteric end of things: We are cataloguing a collection of black and white negatives. In many cases there are groups of negatives depicting the same subject. In some of these cases the depictions are very close (for example, multiple takes of a posed studio portrait, multiple takes of a wedding party) and in other cases the relationship is more distant (for example, multiple exposures taken in sequence during the same event).
We have been using the term "version" to refer to these. We looked in AAT and found the term "version" under the derivative objects section, and discovered that it is meant to refer to objects that are based on an original, which is really not applicable in our situation since no single negative in these cases can be called the original or primary negative. We are wondering if there is another term we should consider using to describe these relationships and particularly if there are two terms that would permit us to distinguish between the relationships that are very close from those that are looser.
