This gray card is to provide a standard reference object for exposure determination in photography. Its apparent brightness (and exposure determination) therefore does not depend on its orientation relative to the light source. By placing a gray card in the scene to be photographed, oriented at a defined angle relative to the direction of the incident light, and taking a reading from it with a reflected light meter, the photographer can be assured of consistent exposures across their photographs. In addition to providing a means for measuring exposure, a gray card provides a convenient reference for white balance, or color balance, allowing the camera to compensate for the illuminant color in a scene. Gray cards can be used for in-camera white balance or post-processing white balance. Many digital cameras have a custom white balance feature. A photo of the gray card is taken and used to set white balance for a sequence of photos. For post-processing white balance, a photo of the gray card in the scene is taken, and the image processing software uses the data from the pixels in the gray card area of the photo to set the white balance point for the whole image. Many serious photographers or hobbyists consider gray cards an essential part of the digital photography process.

    It does what it is supposed to do perfectly and seems high quality enough that if taken care of it will last many many sessions.

    I enjoy the feature this product provides, however I was quite alarmed about the size and inability to fold/compact it down. For the price, it's hard to go wrong, and I would recommend this to all photographers that are beginning to learn white balance editing. I would also recommend this to photographers who do not mind traveling with bigger bags/cases for a shoot. However, for your pick-up-and-go photographers, this is entirely inconvenient. I recently purchased a fairly large camera rucksack, and this barley fits inside without squeezing it down to close the zip. Due to the design of the plastic/metal band that keeps the circular structure intact, this card does not fold down and cannot be bent without causing damage. If you really want a white balance card but like to travel light, pro-tip - print out a page coloured fully grey, fold it down to pocket size or even smaller, and you have the same product but made easy for traveling at a fraction of the cost (the cost of a piece of paper!) Overall, great for photographers in a studio or travelers that have plenty of free space, but it's simply too inconvenient to travel light with. I would recommend this to Model photographers and to beginners who are first leaning about editing white balance.
