    • ISO
    • The term ISO (or ASA) is used to measure the speed of photographic film. The higher the ISO rating the faster the film is, and fast film affords better exposures in low light situations. The offshoot is that the faster the film gets, the more the grain size increases. I have found that higher ISO numbers in digital cameras result in increased noise rather than larger "grain".
    • For the most part, I keep the ISO set to 100 (its lowest) as this renders the best image quality. In order to modify the ISO setting, you must first activate the Menu on the LCD screen. Scrolling with the arrow keys allows you to choose an ISO setting of 100, 200, 400 or AUTO
Exposure Modes
Before You Start....
Once the power is turned on, it is then possible to adjust the settings on the camera. When you purchase a digital camera, the factory settings will most likely be designated to the most basic, or Automatic modes. Although this allows you to start taking pictures right away, you may eventually want to customize these settings to optimize your image results.
White Balance**
Since different sources of light vary in color temperature, it is necessary for a digital camera to have variable color capture settings. In a traditional camera the type of film (daylight, tungsten), as well as filters for the lens, determine how the colors of a shot will turn out.
In a digital camera, you can either choose specific Kelvin temperature ratings (the Sun symbol represents a color temperature of 5500° Kelvin for bright sunny days, the Light Bulb symbol represents a color temperature of 3200° Kelvin for incandescent, or tungsten lighting, etc.) or you can leave it on the AUTO setting (figures 4 & 5). (AUTO enables the camera to make its own interpreted setting.)

Resolution
Resolution is directly proportional to image quality. For the highest quality image, I choose the TIFF format because it does not compress an image file as much as the JPEG format does. However, keep in mind that the higher the resolution, the fewer number of images you can capture on one card.
There are three things that go into factoring how many images you can capture on a card: the size of the card, the size of the chip on the camera (how many Megapixels it is), and what the capture resolution is set to. The chart below shows you how many images you can expect to capture with different combinations of these variables.
