I notice that some established photographers (meaning, they sell their work for good money) offer prints in pretty much a set fashion: one size, mounted and matted one way.
These days one trend (not the only trend) is toward smallish prints on large mount/mat board. I'm wondering how these will play in years to come, considering changes in tastes.
I recall seeing a movie from the 1980s, "Boys From Brazil" (Gregory Peck, Laurence Olivier), in which one scene featured a room decorated with several square format prints that were either unmatted or with very small overmats - I couldn't tell on my TV. Today that would seem rather dated.
Or would it?
I also don't often see the black side of mount/mat boards used. Why is that? There are many images that could benefit from a darker surrounding. Misty seascapes seem to fly away unchecked against white boards. Sometimes I wonder whether that's the real reason Michael Kenna, Rolf Horne and others tend to burn the edges of their prints so dark - because their galleries demand white mats and the subject matter of these photographers would seem ungrounded or fleeting against such a background.
