And if you haven't looked at Escher's perfect illustration of the topic yet, I encourage you to do so. (Click here) With my declining eyesight, a large format camera would help to better see the images in all their detail (of which there is a lot, despite advice to keep images simpler), but I will have to make do with my Nikons.

The current images are just a first step in approaching these topics, taken on July 30 around the Centre Pompidou in Paris. In some cases, the camera position needs to change for better reflections, in others, I should experiment with different daylight and cloud formations, bigger crowds inside and outside, people placed at different positions, etc.
The image above and the next two below have the Centre Pompidou “penetrate” a neighbouring building. I was attracted by the contrast of the rather tame (even lame) metal construction of the neighbouring building and the flamboyant and daring one of the Centre Pompidou.

The next two images treat the subject of “outside-in”: The sloping space in front of the Centre Pompidou reflects in the glass panes of the building. One can see people wakling on the outside being “projected inward”, mingling with people people inside whose image is blurred by the reflections of the outside. The photographer is also projected into the (last) image, despite Erich Kästner's saying:

Merk's dir, du Schaf,
weil's immer gilt:
der Photograph
ist nie auf'm Bild."
