One of the handicaps of a camera (film or digital type) is the need to have good light to make a great picture. Many of today's cameras can take pictures indoors without flash or offer a built in electronic flash. However, adding more light in just the right amount can make the difference between a good picture and a remarkable picture. When you see pictures taken by today's contemporary photojournalists, the definition and tonality of the picture can be awesome. Accurate color, sharp detail and balanced illumination are important parts of great photography. And while some people still think film cameras make better pictures than digital, many who are shooting digital know that their pictures easily rival those shot on film. The biggest limitation to a digital camera is the sensitivity of the image sensor. Even though you can adjust the film speed setting on your digital camera, you really are only adjusting the software. Setting the ISO does not really change the ability of the camera's sensor to absorb light. It is more like tuning the color and contrast control on a television. The one tool that will dramatically improve your photographs is the PROMASTER 7500EDF Digital flash.
