Frame examples...

Black wooden frame.
This works well with black and white photos and a white mount.
Silver frame. This
frame has a slight 'brushed metal finish'. Note, this frame has a black
edge (as seen in the image on the right) which works really well with
the black mount and a black and white photograph. See below...

Silver frame with
black mount and black & white photo. Note that the bevelled edge
of the black mount is white to provide a white border to the photograph.
I do almost all of my own black and white photos like this!!
