A website where I show some of my photographs, and share some of my knowledge.
Panoramic imaging and astro-photography techniques.

Featured photographs :
Tech reviews :
Covers how to colorize partial eclipse images taken through a solar filter such as Baader astrosolar,
shows a simple way to enhance corona details when only one image is available, and exposes a method
to render the solar corona details on a multi-image composite.
A repository of some tests done on commercial brand SLR lenses in astronomy conditions.
Topics cover the focusing sharpness and the lens image quality versus f/stops. The tested lenses
are : the AF Nikon 50mm f/1.4 D, the Sigma 30mm f/1.4 DC EX.Check out our partner site :
Display optimization :
All pages on this site are optimized for a 1024x768 display size and true color depth (24 bits, 16 million colors), or more.Some files may be long to download, due to our dedication to quality.
Tune your monitor :
On the grayscale below, you should distinctely see 25 shades of gray, the first cell on the left (numbered 0) as black and the last cell on the right (numbered 25) as pure white. If not, please tune your monitor in brightness and contrast.| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 |

The technologies used in this website are XML, XSLT, javascript, javascript/DOM, obviously CSS, and... a teaspoon of AJAX. It (the website) is as much as possible based on w3c recommendations, and designed for equal rendering across the platforms and browsers.

With the release of Microsoft Internet explorer 7 in October 2006, the compatibility of this website with previous versions of IE is dropped : indeed, we are now using some CSS properties not supported in these previous versions.
This site has been tested with Mozilla Firefox 1.5 and Internet explorer 7. Other browser users, sorry, no time to test on your platfrom : I have it written on my todolist anyway, and your feedback would be greatly appreciated.
The dynamic effects in the galleries (such as fade-in, fade-out, and transparencies) are provided by the powerful and smart jQuery framework.
