Who would have known that 3D imaging is not the real thing. Well, it is real and there are many technologies that produce 3D images. But the 3D concept is not developed to be fully realistic. What else could be there, you may ask. It's simple:

To create "the ultimate synthetic display", says Ramesh Raskar, an associate professor at the MIT Media Lab, "the display should respond not just to a change in viewpoint, but to changes in the surrounding light".

When you step into the photography realm you hear new words, meaning of which eludes you. One of them, so simple, and still so mysterious is the "f-stop" (or simply "stop"). What does it mean? What does it measure or represent? Read the article "Understanding Light Stops" to be in the know.

Just found a great blog with various techniques about photography. Jim Talkington talks and shows (in video) his view on various topics of photography. Even those who shoot film can find something to learn and read about.

Here is how Jim describes himself:

My name is Jim Talkington and I’ve made my living as a professional photographer for 20+ years. Currently the co-owner of Daylight Photo (a commercial / advertising photography studio) in Cincinnati, OH, my career has wound its way through many facets of the profession: advertising, photojournalism, editorial, catalog, darkroom technician, retail photo sales, writer…you name it, I’ve probably tried it. And I wouldn’t trade the journey for anything.

Here is a good article that explains the filter types and their mounting approaches for DSLR cameras. If you are thinking about expanding your toolset, then take at this article. The usage of different filters can solve various problems (i.e. contrast scene or glare) and dramatically enhance your photographs. The article comes in two parts: Part 1 and Part 2.

Chuck Westfall, who is Director of Media & Customer Relationship at Canon, gives a few answers to intriguing questions regarding photo gear. One of the questions is related to the myth that when you turn the Image Stabilizer (IS) on your lens while the camera is mounted on a tripod, the IS will introduce its own shake to the image.

Here is a quote of what he has to say on this issue:

Next, virtually all Canon Image Stabilizer lenses except the now-discontinued original 1995 EF75-300mm IS model have some degree of tripod-sensing. In most cases, what that means is that when the lens senses that it's completely steady, it effectively prevents the IS mechanism from moving. With typical IS lenses like the EF70-200mm f/4L IS USM or EF24-105mm f/4L IS USM, that’s about as far as it goes. In other words, the IS mechanism doesn’t move when the lens is mounted on a tripod, but by the same token, it doesn’t compensate for other sources of vibration such as the slap of the camera’s reflex mirror prior to the beginning of an exposure.
