Digital photography just keeps getting better and better, and now the traditional leader in high-end photography has actually given in and geared nearly all their products to digital. As things stand currently, nearly 100 million digital cameras will be sold by 2008.

If you're looking to get one yourself, bear in mind that it is important to realize that the quality of digital cameras is related to other factors than the size of the mega pixels. The two primary factors are the size of the computer chip and the quality of the optics.

There is a major difference between a typical point-and-shoot digital camera and a Digital Single-Lens-Reflex (DSLR, with interchangeable lenses). All point-and-shoot digital cameras have sensors typically only one-fifth as big along each side, or only one-25th of the surface area for the sensor as well as for each pixel at the same resolution.

Last year Canon made the first camera that actually produces clearer images than a 35-mm film camera. This is an $8,000 camera -- and it weighs several pounds -- but it produces incredible photos.

However, for most of us, digital cameras that can be easily slipped into our pockets provide more than sufficient resolution power to capture our memories. If you are considering purchasing a digital camera soon you might want to wait a few weeks. The PMA trade show is the Consumer Electronic Show (CES) camera equivalent, and it will be held in about one month.
