Digital camera & digital photography resources
for professional & amateur photographers

Digital ISO speed settings are meant to be used in the same fashion as the film ISO settings after which they're named. That is, for reduced light conditions and/or faster action you would increase your digital ISO settings just as you would pick a higher rated ISO film. While this feature can be very handy and may make all the difference in certain conditions, one of the potential drawbacks of using higher ISO can be the appearance of subtle and sometimes not-so-subtle noise factors.

The biggest contributing factor to ISO noise is the digital camera equipment you use. More expensive equipment tends to produce noise less often or to a lesser degree than less expensive equipment. Depending on the intensity of the noise, it can show up as anything from barely noticeable little dots spread throughout the photo that give it a grainy feeling, to a haze of speckles and an overall harshness.

If you are new to digital photography or are just learning of this potential problem now, you can take heart in the fact that even if your digital camera produces noisy photos at higher ISO settings, you don't necessarily have to avoid these immensely useful settings. This is because the problem can be fixed quite easily on most photo editing software, including ACDSee's built-in photo editor, ACD FotoCanvas Lite.

Depending on your level of experience and critical acuity this could be considered an example of subtle noise and, taken on its own, an untrained eye might not even notice. But when compared to the improved, filtered results, it becomes obvious that there is a problem that should be (and can easily be) fixed.
