3-Plus Megapixel Digital Camera Model

With a 3.3-megapixel digital camera you have really crossed over into the realms of professional-quality image-making. Cameras in this category are capable of producing good-quality ink-jet prints up to A4 size, or even greater. If work requires the type of reproduction quality demanded by a magazine, you can enlarge to A5 size; with non-critical subjects, or certain "artistic" treatments, such as graininess, blur, or other distortion-type filters, then you can safely enlarge prints to A4 and greater, since these treatments disguise any slight imperfections in image quality.

If your camera is intended for professional use, then ruggedness and reliability should be key factors in your decision-making process. In these respects, cameras in this class are generally built to a higher quality and with better electronics and a wider range of features than cameras of lesser image resolution. But bear in mind that these cameras not only cost more to purchase in the first place, but they are also costlier to maintain. This is due to the fact that their larger files require more storage space (images with more pixels take up more memory space) and larger files take more time to work with than smaller ones. So, opt for one of these higher-resolution cameras only if you really need the extra quality.

Note that some cameras give images containing more pixels than the specification of the camera seems able to produce. If so, these figure have been arrived at by adding pixels through a process of "interpolation" and may not represent any true improvement in the detail captured by the camera.

When deciding on a suitable camera, check that the connection is suitable for your computer. As was mentioned earlier, USB is faster than serial, while FireWire is better than either. In addition, check the type of battery: Li-ion or NiMH types are better than NiCd.

There is a growing number of single lens reflex (SLR) designs in this class of digital cameras, but not all of them allow for interchangeable lenses. If your photographic work is likely to demand that you use a wide range of lenses, make sure any camera you are thinking of buying is suitable.
