Full professors at Canadian Universities are, in most cases, extremely accomplished and well respected.
It is extremely difficult to achieve the status of full professor at our universities - there are relatively few full tenured positions, and many, many, many who aspire to them.
I have no direct knowledge of how easy or difficult it is to achieve that status at Professor Bannos' institution.
And Professor Bannos is a professor of photography, so seems to have been working within her field while putting together her book.
