Google Street View car drove down my street today

This was a lucky shot – lucky that I had gotten a glance “of something” going down my street and on a hutch, sprinted for my camera, ran back, saw what it was, and got this shot. This is the second time I have captured their car on my camera. The other time, I was bicycling on an off road bike trail and encountered the Google bike taking pictures. The Google...

Reducing image noise in the Canon XH A1

The Canon XH A1 is not very old, but it is tape-based, which today seems quaint and dated! However, the camera shoots excellent images and its 20x zoom lens remains amazing.  Even at 1440×1080 HDV, it shoots sharper and lower noise images than most of the consumer 1920×1080 camcorders. But when comparing to my Lumix GH-2 in daylight, the XH-A1 has some image noise that resembles film graininess. Some people actually...

DSLRs and rolling shutter

“Rolling shutter” is a video image distortion that commonly appears when using modern CMOS-based DSLRs – and also CMOS-based consumer camcorders. It manifests as a wobbly or skewed image. In the simple case, a fast pan left or right causes vertical lines to become slanted and bent. In a more typical case, portions of the image can appear wobbly if the camera – or the subject – are moving left or...

Canon SX40 HS has much improved video

One my cameras is a Canon SX1IS that I bought used. This model is probably 2 1/2 years old now. But once I figured out how to really use it (think RAW!), I get great results. I really like using this camera for stills – I don’t have to carry a bag for lenses. Sure, its not a gaziggle pixel camera with the world’s sharpest lens, but I am not shooting...

Home made wind suppressing blimp for microphones

After dealing with wind one too many times, and especially in Yellowstone, I decided to build my own blimp. I assembled what you see in this photo: After I built this, I discovered plans on the Internet for this same idea, even using the same components! The tube is made from two inexpensive bird feeders, purchased at Home Depot. The sections are glued together using epoxy putty. Home Depot said they...

Technical description of Canon RAW files

Inside the Canon RAW format version 2, understanding .CR2 file format and files produced by Canon EOS Digital Camera. Mostly of interest to software engineers (like me). If you ever wanted to know more about the Canon .CR2 raw image file format and what gets stored there, this is the place to go.

Firmware update for the lens?

It seems odd, even to me, a software engineer, to be updating the firmware in my camera lens – but its for real. Panasonic released firmware updates for several of their camera lenses, including the standard 14-42mm kit lens: 43 Rumors | Blog | Panasonic firmware update for four m43 lenses!. The improvement is said to improve auto-focusing, image stabilization, and reduce potential focus noise when recording video. I have installed the...

Canon, Nikon market share dropping in Japan

And dropping by a lot due to the shift to smaller, lighter mirrorless DSLR-like cameras: Canon Inc. 7751 and Nikon Corp. 7731, the world’s two biggest makers of high-end cameras, may be missing out on the industry’s biggest technology shift since film rolls became obsolete. via Canon Hanging on to Mirrors Means Opportunity for Sony, Panasonic Cameras – Bloomberg.
