The fact that the book says the OM-2 will do 60 second exposures when it
actually does 19 minute exposures could be interpreted as  reciprocity
correction but I don't think it is.  It's just a long low light exposure that
is not guaranteed.
As in the 2N manual that says low light exposure is 2 minutes when it is 3.5
minutes in actual use.
