Infinity path/different reflections

 I managed to get a better angle for taking pictures of mirrors facing eachother

and also found that putting something between them (a piece of foil here),

gave the impression of a path going back.

I started looking at how different materials give different reflections. Foil gives a much blurrier

reflection than mirrors do and it also depends on if the foil is flat or crinkled or curved etc.

 When you take pictures while moving a mirror the reflection is blurred 

but the rest of the picture stays focused.
