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. 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?

If you want to understand the math behind the process, start with the articles referenced at Wikipedia and you can find as much detail as you want. In a nutshell, it involves taking the Fast Fourier Transform of the image (which makes it easier to see the tell-tale signs of blurring), smoothing out the artifacts, then transforming the image back into its original form.
