Schlieren Photography - Ian.Org (Note: Click any image on this page for a larger view.) I also have a Schlieren Tutorial page I have written up with tips and some explanations on how it all works. Visit Andrew Davidhazy's Schlieren Photography Principles and also Schlieren Optics from Harvard to see where I got most of my information. Both are good resources. The photos on this page are also on My Flickr Account . There are two main ways to set up a Schlieren system.
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!
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. 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 having to shell out the cash for Adobe Fireworks. Why Use PNG Instead of GIF? GIF files only support binary transparency meaning that either a pixel is either fully opaque or fully transparent. On the other hand, PNG (pronounced “ping”) files support semi-transparent pixels and also offer a reduction in size over GIF files when using the 8-bit variety.

Det er Mærsk Mc-Kinney Møller Instituttets formål at skabe et højteknologisk, internationalt anerkendt forskningskraftcenter, hvor universitet og erhvervsliv arbejder tæt sammen om udviklingen af nye teknologier til intelligente autonome systemer. Mærsk Mc-Kinney Møller Instituttet blev etableret i 1997 som en del af det naturvidenskabelige fakultet under Syddansk Universitet. I 1999 rykkede Instituttet ind i egen bygning doneret af A.P. Møller og Chastine Mc-Kinney Møllers Fond. Læs mere om Instituttets oprindelse ved at klikke her og dets nuværende uddannelser og forskningsaktiviteter ved at klikke her (PDF-fil).

MAKE: Blog: DIY: Camera stabilizer This is really great looking camera stabilization rig. It certainly can compete with the professional models and seems to cost a lot less. I really like the universal joint that allows for some incredible movement. Inspired by the Steadicam Merlin , and unwilling to spend Â£500 on that device, I set about making my own, following the basic principles of the Merlin and other similar designs viewable on the internet.

Unwrap Mosaics, a Form of Video Editing Unwrap Mosaics, a Form of Video Editing The Unwrap Mosaics approach by Microsoft Research/ Weizmann Institute was presented at the recent Siggraph conference . In this project a flat surface is algorithmically produced and allows the artist to paint over it, like by adding a moustache to a face; the painted parts then appear in the video and adjust to the camera movements.

Unshaking and refocusing your photos Deconvolution is the general process that helps remove the effects of camera shake and blur. 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. It is a CPU-intensive process, but for a shaky image there is no better use of your MHz.

Turn a TI Graphing Calculator into an Intervalometer and Create I've always wanted to make time lapse videos, but I don't have a camera with an intervalometer feature built in. In fact, I don't think very many cameras come with such a feature (especially not SLR cameras). So what do you want to do if you want to make time-lapse videos?

With a digital camera in movie mode, or with a camcorder, the diy infrared filter can also be used to record videos, giving them an eerie and mysterious atmosphere. However, due to the short exposure of video shots, it is hard to get satisfactory results with two pieces film. In the video on the first page of this instructable, as well as the one underneath, the footage was recorded through a single slide of photographic film, which does let in a fair amount of natural light, as well as IR light. The result is an hybrid, which has an interesting mood to it however. A better diy infrared filter - Take stunning digital IR pictures
This post on enhancing contrast in digital photos was submitted by Leeroy Gribbon whose photoblog ( www.decoy.co.nz ) we recently featured here at DPS as Photoblog of the Week. I’m a sucker for good contrast in a photo. Since I mainly like to dabble in monochrome work, contrast for me is the gravy train – second only to composition. 5 Techniques for Enhancing Contrast in Digital Photos
