Sony Cybershot DSC-HX1

One of the cool tricks you can do with digital cameras is called panorama shooting, which links a series of photographs together into a single image. The problem is that all cameras today require you to take separate images and then link them together on your PC.

Samsung TL34HD

Just when you thought digital cameras couldn't get much better, Samsung has raised the bar. The TL34HD offers a whopping 14.7 megapixels of image resolution in the palm of your hand.

image conscious

When I first started ogling digital cameras, a snapper capable of taking 3-megapixel resolution photos was pretty splashy. Now, you expect at least double that figure.

Toshiba brings picture technology up to date

In 1911, a Russian scientist created a television system that used a mechanical mirror-drum scanner to transmit very crude images to the receiver. Moving images were not possible then.

In 1928, a Scottish engineer demonstrated the world's first colour transmission.

Sharper images

High-definition video (HDV) delivers the widescreen vistas, clarity and colour depth of movies to the television and computer screen. Building on the success of its first professional HDV camcorder, the HVR-Z1P, Sony has unveiled an ultra-compact version of that product, the HVR-A1P.

Good resolutions

HOW MANY MEGAPIXELS? That's always the first question people ask about digital cameras. It seems like the most logical question because that is what manufacturers tout about their new models. If you dream about making large prints from an inkjet printer in a digital darkroom, then megapixels are something you need to consider.

Light thrown on human vision

A study on monkeys by anatomists at the University of Hong Kong has debunked a theory on why humans evolved their unique red-green colour vision.

The theory espoused since 1879 is that the three-pigment (primary colours red, blue and yellow) eye structure allowed humans to look for ripe fruits against green foliage.

Quest for the best from digital cameras

I would appreciate if you could explain these: Using a 300 dpi printer to print a 4 x 5 inch photo, the file size should be 1.8 million pixels (1,200 x 1,500 pixels) for perfect fit. Hence, can I conclude that my digital camera should have a resolution of 1.8 million pixels in order to take full advantage of the printer?

A better view of digital matters

When I popped in to see grandma, I always knew if that 12 exposure roll sitting in her camera for the last six or eight months had been polished off.

Out came the packet of prints as she talked about this uncle or that cousin. At the bottom would occasionally be one shot that contained some bleach white figure or dark blob.

WebScan helps pin down viruses in Internet files

I USE the Internet a great deal, but live in fear of contaminating my system with a virus that could attach itself to one of the many programs I constantly download onto my PC.

I use Norton AntiVirus to scan all the programs I download after they are on my hard disk, but it would be so much more convenient to be able to scan them as they are downloaded.

DESIGNER cosmetics could become collectors' items as cosmetics houses are introducing limited-edition products and packaging available for one season.

One of the first companies to introduce this concept for its spring/summer 1995 make-up collection is Chanel.
