The photographs were taken on 10 and 12 April 2002.

The camera used is an old PENTAX with a 28 mm 1:2 lens (image at the top) and a 50 mm 1:1.4 lens. A Kodak 100 ASA Farbwelt 35 mm negative film was used. It was developed and scanned on a GRETAG minilab which writes 2100 x 1400 pixel TIFFs on CD. Editing, i.e. removing of blemishes, making occasional adjustments for brightness and color saturation, scaling the images down to 1050 x 700 pixels and finally converting them to JPEG, was done with GIMP.
