Clockwise from top left:

• Cabbage tree
• My washing basket
• A black carousell holding white cardboard slides
• My kitchen floor
• Center: the prism mounted on a 135mm lens on an APSC camera a friend lent to me.

These are basically straight out of the camera, with minor adjustments in RawTherapee and combined into one image with InkScape.
