How to make a fish eye lens for a Nikon D-90 Digital SLR for $16. I got the inspiration to do this Instructable while reading another Instructable that accomplished the same "fish-eye" effect using a PVC reduction pipe and an entry door viewer.
There was concern in the prior Instructable about around scratching the lens so I wanted to solve that problem in my easy to build fish eye lens as well as make a version which is easy to use, remove, etc. I decided to modify the design by using an existing camera attachment which would easily mount to the camera and comes with most Nikon lenses. The secret to my design is to use the lens shield as the attachment platform which allows the fish eye lens to be easily attached and removed from standard lenses while enabling a hands free experience.
Review of multi-flash imaging with the non-photorealistic camera. I recently visited Ramesh Raskar at the Mitsubishi Electrical Research (MERL) lab in Cambridge, MA to learn more about his multi-flash camera innovation that recently made an impressive appearance at the SIGGRAPH 2004.
Raskar has been working on the multi-flash system for 3 years in collaboration with Karhan Tan, Amit Agrawal, and Rogerio Feris. If you grew up in the 80's, and watched early MTV, you might remember A-Ha's "take on me" line drawing animation video. Unfortunately, for the "take on me" video directors, Raskar's innovative technology was some twenty years away! Alpha Transparency in PNG-8 Images Without Using Fireworks. Web designers are starting to discover that 8-bit PNG files can be used to achieve semi-transparency (alpha transparency) that will gracefully degrade in IE6 and be much more compact than the same image saved as a PNG-24.
Most of the posts around the web focus on using Adobe Fireworks to achieve semi-transparency, but what about the rest of us that don’t use Fireworks? Today, I’ll demonstrate an alternative technique to show you how to achieve alpha transparency in PNG-8 images without Adobe Fireworks. Why Use a PNG Instead of a GIF? Image Processing Library.
