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 onto a photo CD. Editing was done with GIMP, i.e. removing blemishes, making adjustments for brightness and color saturation, scaling down, slightly sharpening and converting to JPEG (quality setting 80%).
