Gimp Scripts

• Adjusting color temperature: colortemp is a Gimp script for changing the color temperature of images. This script-fu script enables you to change the color temperature of an image to any specified temperature. It can be used to correct the red color cast of photos taken under incandescent light with the camera on daylight setting, or to correct the blue cast of outdoor photos taken in overcast conditions.
  
• Adjusting white balance: whitebalance is a Gimp script for changing the white balance of images. This script-fu script can be used to convert the foreground color to either a neutral gray, or to the color of the background.
  

You can find tutorials on the use of Gimp at the Gimp home page, as well as at Gimp Wiki and at Digi Grey.

Making Photo Galleries with Captions

• makeshow is a small Python script creates a photo gallery web page from a directory containing images, automatically resizing all the images, and creating the thumbnails. The script also creates captions: a caption to a file xyz.jpg is specified by including a caption in a file named xyz.txt in the same directory. It requires ImageMagick.

• Making Black and White Slides is fun! Not only are black and white slides truly beautiful; they are also quick to make - much quicker than printing. There are many ways of making b/w slides: my approach consists in taking the photos with normal b/w film, then duplicating the negatives onto special film to obtain slides. If you would like to learn how to make them, read my instructions.
• Acufine Development Times. Acufine is a developer that is good for pushing film. I like it very much for Ilford HP5+, for which it gives me a higher speed than other developers such as HC-110. I copied some data sheets that Acufine Inc. sent me.

• WikiTrust: an author reputation system and text trust system for wikis.
• Using Latex in OpenOffice: I adapted a package that enables you to use Latex in OpenOffice presentations. The package is very much inspired by the TexPoint package of George Necula, and was originally written by Geoffroy Piroux. This is my own version, with (I believe) improved fonts and symbols.
• Vec: Extensible, functional arrays for Ocaml. The module provides log-time insertion, deletion, modification, concatenation, and much more. If you have ever missed in Ocaml the flexible lists of Have you ever missed in Ocaml the flexible lists of Python, now you have it in Ocaml, implemented in functional fashion.
