Why Film And Digital Cameras See Color Differently
In conventional photography, color adjustment is accomplished using either color-correction filters or color balance film.
With the exception of professional films, all film sold are balanced film. The film boxes shown here display two different
ways (daylight and outdoor) to indicate film that is color balanced for daylight. Daylight-balanced film is so common that
many film boxes no longer indicate that the film is color balanced for daylight.
For the digital photographer, color temperature correction is accomplished by camera. Called white balance (WB),
it is a new concept for most conventional photographers, although videographers have always worked with it.
WB controls what a digital camera perceives as neutral color. Without WB correction, white objects tend to
appear reddish-white under incandescent lights, slightly green under fluorescent lights, or bluish on an overcast day,
just like daylight-balanced film under the same lighting conditions.
Understand Color Temperature
Every light source has color temperature that effects how colors appear. Table 6-1 (Dave Huss, How To Do Everything With
Digital Photography, pg 81) shows a brief summary of light temperatures and their perspectives effects on subjects illuminated
by these sources. You don’t need to memorize the information on the table; it is provided so you can see the effect that different
color temperature has on how colors appear. For example, high temperature produce cooler colors and low temperatures produce warmer colors.
