EXIF is one of the most frequently used digital photography acronyms. EXIF stands for Exchangeable Image File Format. EXIF information, embedded in each photo file, is made up of metadata including date, camera settings, a small preview image, descriptions, copyright information and GPS coordinates.

A few weeks ago I read about some amazing Crystal Caves discovered in Mexico and was blown away by the photos! (Thanks Raoul via Twitter) This week what little skepticism I had of this story is now gone seeing as how National Geographic is now reporting the discovery as well. Check it out.

This was the view of Chicago’s skyline as seen through Cloud Gate (AKA the Bean), an often photographed sculpture, in Millenium Park. The beautiful weather lasted only 3-4 hours on this morning and then it turned stormy.

This weekend in San Francisco was one of the whackier events, Bring Your Own Big Wheel (BYOBW). The curviest street, Lombard Street, is shut down for 1 hour so daredevils can take their fate into their own hands by riding down on plastic wheeled tricycles. No rubber wheeled vehicles are allowed at any time. This year thousands were in attendance and hundreds took part. My only regret was not finding a Big Wheel in ti

“Depth of field (DOF) is the distance in front of and beyond the subject that appears to be in focus. There is only one distance at which a subject is precisely in focus, but focus falls off gradually on either side of that distance, and there is a region in which the blurring is imperceptible under normal viewing conditions.” – Wikipedia DOF field varies with aperture, from shallow at wide aperture

Another shot of the Bridal Veil Ravens from a slightly different vantage point. As previously noted: “Surely one would think the locals would get tired of the view in Yosemite, but on this very cold morning that didn’t seem to be the case. Perched from a lookout I spied a pair of ravens in a much better position to enjoy the distant view of Bridal Veil Fall. All components of this image have been compressed t
