INSPIRATIONAL: Femto-Photography by the MIT Media Lab’s Camera Culture group


Whilst Yogi, may be smarter that the average bear [link], his certainly not faster than your average photon but I guess that's really like comparing apples with flying saucers, although capture is invovled in both processess. My point is this is pretty crazy actaully been able to see the lighting effect as a result of a passing photon over various surfaces. Literally to be able to see the passage of light. The capture technology using a effective shutter speed of 2 trillionths of a second was developed by the MIT Media Lab’s Camera Culture group in collaboration with Bawendi Lab. I love how you don't have to be a rocket scientist to appreciate the beauty in the video but would have had to to design the technology.    

Here is the TED Talk given by  Ramesh Raskar talking about the potential of this technology with a much higher res image of the above video and a few others for good measure.

TUTORIAL: Autofocus Fine Tuning by easy exposure


Is your cameras autofocus spot on? 

A very informative, comprehensive and easy to understand tutorial on autofocus fine tuning, by Easy Exposure [link]. You may have the best lens and camera combination that money can buy, but if the auto focus is off by a smidgen, kiss the sharpest possible eyes goodbye in that textbook portrait (using a Canon 85mm f1.2 shooting at f1.2) kind of way (assuming here you are using autofocus (if you are using manual focus well it's you not the camera so get your eyes checked [link] and or diopter adjusted [link] )). You owe it to your paying customers to be spot on each time and until Lytro [link] comes out with a more professional grade model that doesn't make you look like you are shooting the entire campaign on a mobile phone or a new focal plane shifting tool ships with CS7 you better get with the program.
