When taking digital photographs, a gray card can be an important accessory in the creation of the white balance and get accurate color representation. The digital camera records the color of light very accurately. The eyes and brain are extremely adaptable to change, it is not digital, it records what is there. Something may look white, but if it has a color cast, which will be displayed on the digital file.
Using a gray card, the camera can be set to true white balance, resulting in a more accurate recording of all colors. This is particularly important when there is a mixed light from different sources. There may be a mixture of light and tungsten, fluorescent and even a little thrown in.
Gray card is a card, which is gray. These days, they are often made of more durable material than the card, but they are a neutral gray. Senior photographic gray cards are not suitable because they are not sufficiently neutral. They have been used assessment of exposure, not white balance and color neutrality.
Photographic gray cards have a reflective surface of 18%. Digital cards are usually gray reflective surface by 18% or 25%. It does not matter, what matters is their accuracy, they must be neutral gray.
Gray card should be placed in such a way that the image of light falling on the subject also falls in a gray card. White balance is derived from reading the card. Photographs should be taken in raw and not as a JPEG in the camera.
Short bench to copy the proper use of the flash or tungsten lighting, the best way to picture the image is on the outside. Choose a clear day scattered light and direct sunlight. The only way to make an accurate white balance is to use a gray card.
The sample uses the card to the left with a true white, 18% gray and black. Setting the tone for the picture gives the interpretation of colors as possible. Without the black card, there is no chance to get to the paint color will look like the originals.
When the lighting conditions are fully controls, such as a studio, a gray card is still an important gadget. Exposure and color balance should be consistent in each image. Based on the automatic reading apparatus of the conditions means that the item is changed, the readings will change. With a gray card digital photographer can take a specific reading of a single target point and the white balance setting is good for all images in this light, even when the subject is changed.
Two objects may be the same color in one type of light, but it can be different colors in different light sources. For example, matching scarf and handbag can look on the other, different colors of light. This is due to the amount of ultraviolet radiation of objects absorb and reflect. Using a gray card can help minimize the problems here.
The cube has a gray card for more details. Six pages are black and white cubes and gray, but it also has other functions.
