Filters for Digital Cameras

Filters for Digital Cameras

With film cameras filters have traditionally been used to modify both the spectral content (color) and intensity of light, as well as generating special effects like soft focus. Digital cameras operate somewhat differently with respect to color though. Color modification can easily be done "in camera", and that's what you're doing when you set white balance. So while for film warming and cooling filters, or filters which convert fluorescent light to look like daylight, may be required, digital can achieve the same effects by internal manipulation of the digital data.
