I couldn't find another thread "devoted" to triptych (if there is, please mods, merge this one there). I'm not after the most strict definition of it, but just 3 images matching together in some way, both horizontal (the usual) and vertical.
I'm giving it a first shot with 3 panos in a vertical triptych. The images themselves don't make up one "new" image as per usual, but do together describe the context which otherwise could be hard(er) to get.
Here goes (6x17, Kodak Portra 400, 75mm, f/22, f/22 & f/32) my triptych of a hanging bike roundabout in a city near to me (Veldhoven).
