Genesis karta za kalibraciju balansa boje (crna, siva, bijela) - Digital Grey Card

Genesis Digital Grey Card is easy in use and handy tool helpful to set a proper white balance on pictures. By use of the three cards from the kit, you can easily get a precise WB which can be used in your camera to shoot in JPG format, or later as a reference when RAW file editing in special software. The Genesis DGC is also useful to determine proper exposure in case of products or scenes which can affect light metering in camera.
Each card included in the kit is are coveren on hoth sided with special material with neutral spectral characteristics. The light reflected from the card surface has exactly the same color as the light falling on the photographed scene. because of this the proper white balance can be aquired.
Genesis Digital Grey Card as a light metering reference.
The built-in camera's light metering is calibrated to middle gray, which corresponds to the surface which reflects exactly 18% of incoming light. In most cases, this method of light metering works fine, and is proper for popular scenes. Unfortunately, in some extreme lighting conditions or scenes with complex lighting, the built-in light metering may set exposure parametres which are not adequate. For example: when taking a photo of white or black surface, it will be exposed to middle tone. The solution is to set the exposure parametres manualy by metering the light reflected from the grey card.

White card
Both sides of the card are white and have a neutral spectral characteristics which reflects 90% of falling light. The card may be used as a reference for setting a white balance (automatic exposure must be turned on). With a combination of grey and black cards, it can be used for checking the scene contrast.
Black card
Both sides of the card are black and have a neutral spectral characteristics which reflects 3% of incoming light. With a combination of grey and white cards, it can be used for checking the scene contrast
