An experimental tool post to crowdsource the average 'gamma value' for the
world wide web. To learn more about gamma you can read the FAQ and also the FQA by Charles Poynton.
Instructions
1. Use '+' and '-' buttons to make the corresponding patches above the buttons lighter or darker.
2. Create a visually equal spaced gray ramp from black on the left to
white on the right. That is the jumps in lightness between neighbors
should be roughly equal and the ramp should be getting progressively
lighter.
3. Click on the 'Plot' button to see your results(black) plotted versus the world wide gamma(red).
Note that users of older versions of Safari (ie 1.3.2) have reported that this post
is not interactive, but it has been tested with newer versions of Safari (ie 3.1.1) and the post is functional.

Color names are a powerful means of selecting and communicating colors.
There are a variety of color vocabularies and dictionaries available
but there has been less work in capturing the similiarities and
differences in color naming. This post is a tool post in that the
online color thesarus is embedded directly in the post.

Recently I received a comment on an old 5 March 2007 post, asking me for my thoughts about how digital photography's development in the last ten years has changed the way we take photographs. I am writing a new post instead of adding a comment to an old post because on this page you see only the current posts, and making this current allows more readers to comment. |

| I am often asked for printer recommendations. Many people think there is a single metric to rate a printer, for example the resolution in dots per inch, but then when they visit a store, they are overwhelmed by the choice. Often a manufacturer has even more than one model at the same price. How do you buy a printer? |

Today is another perfect day in Silicon Valley. The weather at a balmy 23ºC, blue skies, perfect for a walk on the beach, a hike in the woods, or to drive down to San Jose to attend the First Multimedia Application Formats Awareness Event organized by NIST (National Institute of Standards and Technology), INCITS (InterNational Committee for Information Technology Standards), and MPEG from 8:30 a.m. to 2:00 p.m. |

In February I wrote about Siliva Zuffi and Carla Brambilla's work on the readability of colored text on a colored background (permalink). In the second paragraph I mentioned Gordon Legge's work. Legge has revisited his work and compiled it in a must-have book for anybody doing graphical user interfaces or working on digital publishing. |

| This is the name of the current exhibition at the Musée de l'Elysée in Lausanne, a museum devoted entirely to photography. There are two opportunities for you. If you are an amateur photographer, you can exhibit your photographs. If you are a researcher in image retrieval, a large new corpus of amateur images will be available for research. Read on for more. |

| Yesterday afternoon I drove the last VIP to the airport and also for this year EI is over—the event that is, for the new collaborations and insights sparked by the symposium will keep us busy over the next year. The main benefit of conferences and symposia are not the papers per se, those will be available online from the SPIE Digital Library in a few weeks, using the program. |
