Ah, it's that time of year again where we reflect on the technology that arrived and got us to open our wallets and try to predict what will tempt us in the coming year to toss last year's model for the new shiny shiny.

In past years, when it came to digital cameras the majority of announcements at CES were for refreshes of budget and style lines with the exception of a few with some attention-grabbing feature or design.

However, a big reason for that was the annual Photo Marketing Association's PMA trade show that followed CES … Read more

Regardless of your feelings about 3D, there's really no stopping the onslaught of products now. Hence we have Sony's Cyber-shot DSC-TX9 and DSC-WX5 that offer the ability to shoot 3D panorama photos.

The TX9 replaces the TX7, which is barely 6 months old. It has the same body, touch-screen LCD, and lens as that camera, but its backside-illuminated Exmor R CMOS sensor gets a resolution bump from 10 to 12 megapixels. The WX5 replaces 2009's WX1 and again is built essentially the same as its predecessor, but with the higher-resolution sensor. However, along with the increased megapixels come important shooting feature differences.

First, there's that 3D stuff. In addition to the Intelligent Sweep Panorama found on Sony's earlier Exmor R-based models, these have a 3D Sweep Panorama. Press the shutter release, sweep the camera vertically or horizontally, and the camera captures left and right images and then stitches them together. You then connect the camera by HDMI to your 3D-ready HDTV, pop on your glasses, and enjoy. The results are good, especially considering how easy it is to create them and that they're single-lens cameras as opposed to dual-lens cameras like Fujifilm's Real 3D W1.

The 3D fun doesn't stop there, though. Both cameras have a Sweep Multi Angle option that captures a series of shots at different angles and then combines them into one shot. Tilting the camera left and right plays through the photos, creating a lenticular lens effect. The result is very similar to what you can do with any camera and Start 3D, but these can only be viewed on the camera. And going by what was said at the demo Sony gave us, it seems like it's mostly just a gimmick to sell 3D cameras at retail stores to people who don't own 3D HDTVs. … Read more

Unless you follow the latest trends and features of digital cameras, there's a good chance Apple's use of a backside-illuminated sensor in the iPhone 4 is the first you've heard of the technology. These sensors have been popping up in digital still cameras and camcorders since Sony rolled out its HDR-XR500V and the HDR-XR520V camcorders featuring the company's own Exmor R sensor in February 2009.

The key benefits are improved speed and dynamic range, as well as better low-light performance with lower noise.

Camera phones generally use a front-illuminated CMOS sensor because they are low power … Read more
