    Samsung UA55C9000 3D LCD TV

    At $10,000, the Samsung UA55C9000 costs more than twice what an otherwise similarly specified, similarly sized, Samsung TV would sell for. So what’s so special about it? We reckon that several of the more extraordinary features justify that price.

Cards and formats and connections

Storage

Digital camera storage cardsDigicams use flash memory cards to store the digital pictures: think of these cards as 'digital film'. After you've taken your shots you can transfer them to a computer direct from the camera or by ejecting the card from the camera (turn it off first!) and loading it into a card reader, connected to your computer. At this point the images become digital files in the same way as documents written in MS Word are digital files.

There are, unfortunately, many types of memory cards: the main ones are CompactFlash, SD, xD-Picture Card, Memory Stick. They are reasonably cheap: a one gigabyte card will cost you less than $25; a one gigabyte card will hold hundreds of images... buy two!

When buying memory cards you may be drawn to the attractions of the higher speed cards, such as SanDisk's Ultra range and Panasonic's Class 6; unless your camera is specifically set up to use the higher data transfer rate of these cards, you don't need them.

Formats

Most digicams shoot images and write them to memory as JPEG files. Written to the camera's memory in compressed form, this is a most efficient format, saving space, making them easy and quick to open and deal with.

You may also encounter cameras that save images in TIFF as well as RAW formats; both are larger, pro level formats, occupy more memory and take more time to deal with. RAW has big benefits for the more expert photographer as it allows you to tweak the original shot to unimaginable levels.

Nikon Coolpix S700 digital camera

A slimly styled camera, the Nikon Coolpix S700 has 12.1 megapixels on board. Price: $649

Connectivity

All digicams will even offer a USB port to connect the camera to your computer. All will offer an AV port, enabling you to run your images on a TV direct from the camera and the big attraction is that many cameras can now shoot images in 1920 x 1080 pixel resolution and provide an HDMI output, enabling you to run a 'slide show' on your 'Full High Definition telly!

Some cameras offer wireless connection to a computer, taking the tangle of cables out of the equation and off your desktop!
