The white side can also be used as a reflector to macros seeking in this area.
The gray side is mainly for the color balance (although) they are used for the exhibition as well. To use it, take a photo with the gray card at the same angle of light and matter. It must be intentional, all in accordance with the neutral gray.
Image in Photoshop and then drag an adjustment layer levels. There are 3 pipettes on the right to choose to center (gamma) ein. Click on the gray card, what it does is change the pixel under the mouse gamma-neutral, ie red = 127, blue and green = 127 = 127, data in the rest of the image to the data and have focused immediately corrected the color balance . The same method can be used non-destructive RAW converter by using the pipette from the white balance of the top row.
You can save the profile, go to control levels levels (top right) and save the profile or the RAW converter to save the settings. This profile can be added to all orand pictures taken during that meeting.
This works best on RAW files and all data are not yet possible, "the file into pieces (about the data file) when it is stored in JPEG format.
This technique is particularly useful for people to imagine that there are many times when it deceives the eye and the camera, you can only choose the preset color balance. Situations such as the interior of a forest where the foliage is usually leaked the red and blue sides of the spectrum, this technology really "Pops" is again the picture quality in full color.
The interior of buildings is another example where the lighting could be a mixture of tungsten and fluorescent materials and the sunlight through the windows. With this technique, a simple click-and-go, the difference is very noticeable. The British Museum is delicately painted a neutral gray walls just for this technique if you forget your gray card!
Photos taken at night is another example of the illumination of several (different) sources. The list is long, much more useful than people orInk.
Even on a sunny day outdoors, the effects can be reviewed, particularly if the subject is in shadow and light is actually a green color as the light reflects off the grass, not seen, was not the device that the gray card! If the camera has done well to then there is no change. As I said earlier, you must shoot in RAW to get the full effect to this.

The 18% gray is used to obtain more precise measurements of light to issues that trick usually feet, shooting like snow or dark subjects.
The white card is used to calibrate the white balance.
There must be a manual, with the gray card.
