Red, Green, and Blue are the 3 primary colors that form the white light. They are mixed in various proportions – depending upon the color temperature of the light. If the color temperature is high – the light is bluish. If it’s low – the light is reddish.
Definition of White Balance
The white balance is used to remove the unnecessary color casts so as to make the image look more natural. Hence, it is set according to the color temperature of the light sources.
Working with White Balance
In most of the cases, a white balance is used to avoid the casts. While some photographers choose to use the “wrong white balance” to produce very creative pictures. You can also create very warm pictures if you use the “shade mode” in the daytime. The opposite (cold) is valid if one is using “tungsten mode”. While DSLR has special mods for all the different types of lights – it’s not really necessary that you must use flash white balance when you use the Speedlight or strobe. Most of the modern digital cameras will calculate ambient light and provide you with a decent result on an “Auto White Balance Mode”, specifically when two or more color temperatures from the different light sources are mixed in the one set. In such cases “Auto white balance” is good to use, or neutralize particular light sources with color filters or gels. There is also the more professional way to set up the white balance by using neutral white, it called “Custom White Balance”. Most of the DSLRs will have instructions on how to set up the “Custom White Balance” for your particular camera.
While shooting on film was required to adjust light sources with filters and gels. However, when we are shooting with the digital camera, it’s easier as you can use the Auto White Balance (AWB). Also, if you photograph using RAW or DNG format, you may adjust your white balance later while processing the images. However, some of the details may be lost if the transformation is too dramatic. So it is always recommended to use the correct white balance during the shooting. To adjust the white balance in RAW pictures, the photographers use “Gray cards“. They are put within the set later as they help in picking the neutral gray during postprocessing.
P. S White balance in food photography is usually aiming the daylight color temperature (except for some special occasions like candle light dinner or so). That’s why many food photographers say that natural light makes food look tastier.
