The 64 water jets in André Citroën park are a lot of fun for children during the last days of summer.

A short jump in Normandy …

One would expect some Eiffel Tower or Louvre pictures from Paris; the truth is I didn’t have the time yet to go on a “photo tour” in Paris except for a couple of visits in the park.

I am now back to Paris after more than four years in NYC. These two last NY pictures were taken from the 52nd floor rooftop in Upper West Side just the day before we left NY.

Two pictures from this year’s offstage preps…

This weekend I got a 16 mm fisheye lens. This leans is really wide; I have to pay attention so that my feet do not appear in the picture.

While the fisheye is not particularly suited for architecture, I use Hugin (open source GUI on top of panorama tools) to “defish” the images. The rectilinear projection (a standard lens is rectilinear) yields and horizontal angle of view of 129° (this is way too much for a rectilinear projection, usually limited to 120°) and a vertical angle of view of 86°. This is the equivalent of a rectilinear lens with a focal length of 8.5 mm horizontally and 13 mm vertically. Of course the 3/2 image ratio is not respected anymore, the corners are somehow soft due to extreme stretching and the objects on the sides have a crazy perspective, but these angles of view are so extreme that it opens a lot of possibilities.

I have to explore more on different projections and find a projection somewhere between the fisheye (too curvy) and rectilinear (too much perspective distortion).
