We see them everywhere, digital cameras are now in cell phones, computers and of course are available in tiny, and yet powerful, pocket sizes as well as in traditional SLR formats. In the past decade alone digital photography has made some remarkable advancements and it is now available to almost any consumer anywhere.

Today’s digital cameras can be almost entirely pre-programmed and full of all kinds of “modes”, but there are also some that look exactly as standard 35mm cameras, including all of the manual settings and adjustments. Such cameras range from the remarkably professional to something now known as the “prosumer” models.

Before jumping into the ownership of a new digital camera it is a good idea to consider what it is going to be used for, who is going to be using it, and what is going to be asked of the camera. For instance, anyone hoping to have constant control over the shutter speed, ISO and aperture of their camera may not want to go with one of the point and shoot models and should instead investigate their options in the prosumer cameras. If, however, the camera is going to be used by someone without a great deal of interest in pursuing specialized photography, the point and shoot would be remarkably effective.

If still not clear about which cameras to look at, it is a good idea to determine what the manual settings can do for the photographer. For instance, a night time mode on a camera may not always capture the sort of images the owner is hoping to take, and this could be for a number of reasons, including the fact that shutter speed or ISO cannot be changed.

Simply understanding how these settings affect an image is the most important thing about using the new digital cameras. ISO translates to the amount of light allowed into the sensor, and increasing the ISO setting may make it easier to capture action shots without any blurring from motion, even in lower light situations, but it will have its “down side” as well. It is important for digital camera owners to understand that changes to ISO, and shutter speed, can cause a graininess called “noise” in an image. While they can be used to create a special effect, most people do not want “noise” in their photographs.

This often leads to the use of software to clean up or enhance digital photographs. There are many modern programs that have “noise reduction” filters that help to fix photographs that have suffered such effects. Purchasing a high-end digital SLR camera usually makes the purchase of compatible and affective computer software a necessity as well.
