Correcting the white balance remains a standard procedure done prior to capturing a photograph. The advancements in digital imaging have still not gotten rid of this age-old practice of capturing an image. Taking a photograph without undertaking the proper white balance can result in the improper registration of colors. Digital sensors function just like the human eye by converting light into varying electrical signals that are processed to form an image. However, image sensors still lack the ability to distinguish between colors in varying lighting conditions.
This causes the colors to become altered when the image is taken in different lighting conditions such as sunlight, tungsten, or fluorescent. Varying lights such as under daylight or artificial lighting sources can cause the colors to appear wrong in a digital image. Proper white balancing can actually prevent the camera from capturing the wrong colors by instructing it about the properties of each color when viewed under varied lighting conditions.
White balancing is given utmost priority in professional photography for the accurate rendition of colors in the captured image. Any irregularities in the color are corrected in postproduction to create an effective separation of all the colors in the image. All digital cameras contain several automatic white balance features that adjust the cameras to different lighting conditions. Setting a specific white balance option depending on the quality of light can automatically adjust the camera to accurately capture the colors.
However, professional photographers use advanced options for carrying out white balancing. There are two in-camera options known as Custom and Kelvin that can actually provide more accurate white balancing of the image. The Custom preset requires photographing against a pure white screen or card at a specific lighting condition for instructing the camera to capture the colors as it is. The Kelvin option actually involves carrying out adjustments in the color temperature so that the image contains all the colors in their exact manner.
Product, architectural, and other types of photography uses advanced white balance correction methods to render the colors accurately. Since they are used for various publications or online platforms, the colors need to be exactly as it is to convey a product or property correctly. Even with proper in-camera white balancing, the resultant image still needs to undergo various image-processing techniques while editing. These techniques are carried out by professional photo editing services to further refine the image and correct any improper reproduction of colors.
