Making of Canon L Series 500mm F4L IS USM. Part 1 of 3 in the production of expensive camera gear. L series is Canon's Premium lens line featuring fluorite lenses. IS refers to Image Stabilzation build into the lens, and USM refers to Ultrasonic Motor drive that makes focusing faster than older systems. Currently I'm using a Rebel XT, although I'm thinking of upgrading to an XTi or 5DMk2. This 500 with the New 5D would be a sweet combination. www.razorfantasygirls.com

Constable Al Arsenault shows a slide of a wide-eyed 18-year-old girl taken outside a bar in downtown Vancouver. 'Does she look like a drug addict?' he asks a class of high-school students. When they answer no, the officer shows them the next slide of the same girl, Shannon, six months later. Her face is bruised and covered in festering sores. 'She's on the needle. She didn't know she had an 'addictive personality'. She does now.' The students express their shock and disbelief. Arsenault, along with six other policemen, began video-documenting the people on their beat to create a powerful educational tool to help prevent drug use among young people. This unique group of officers, who formed a non-profit group dubbed the Odd Squad, resulted in an unusual relationship between the police and addicts in Vancouver's Downtown Eastside. Through a Blue Lens tells this moving and compassionate story. In this documentary, addicts talk openly about how they got to the streets. Through their participation in this video, they want to stop others from joining their nightmare.

Into the Lens by Yes Steve Howe, Alan White, Chris Squire, Trevor Horn & Geoff Downes Memories, how they fade so fast Look back, that is no escape Tied down, now you see too late. Lovers, they will never wait. I am a camera Take heart, I could never let you go And you, always let the feeling show Love us all, how you never broke your heart You lose them If you feel the feeling start. I am a camera, camera, camera And you, may find time will blind you This to just remind you All is meant to be. There, by the waterside Here, where the lens is wide You and me By the sea Taken in tranquility. Taken, taken so easily To pass into glass reality Transform, to transfer, to energy. Taken, taken, so easily To pass into glass reality Transformer, transferring energy.
