The left half shows the photo as it came from the digital camera. The right half shows the photo adjusted to make a gray surface neutral in the same light. In photography and image processing, color balance is the global adjustment of the intensities of the colors (typically red, green, and blue primary colors). An important goal of this ...
The visual weight and the balance of a figure inserted in an image can be determined using the lightness of the figure, the lightness of the ground and their sizes and positions interactions in the composition visual. We establish that an image is totally balanced when the resultant force is located in the geometric center of the image.
The composition techniques in photography are mere guidelines to help beginners capture eye-catching images. These provide a great starting point until an individual is able to outgrow them in capturing images through more advance techniques. Karol ruiz muro
A red object, for example, will be very pale in the red-filtered image but very dark in the other two images, so the result will be an area with just a trace of cyan, absorbing just a bit of red light, but a large amount of magenta and yellow, which together absorb most of the green and blue light, leaving mainly red light to be reflected back ...
Nevertheless, it is important to measure a camera's color response: its color shifts, saturation, and the effectiveness of its white balance algorithms. Distortion is an aberration that causes straight lines to curve. It can be troublesome for architectural photography and metrology (photographic applications involving measurement).
White balance bracketing, which is specific to digital photography, provides a way of dealing with mixed lighting by shooting several images with different white point settings, often ranging from bluish images to reddish images.
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.
Example of a photo with a uniformly green colour cast due to differential absorption of light before reaching certain depths at sea. The same photo with the colour cast corrected. Most digital cameras try to automatically detect and compensate colour cast and usually have a selection of manually set white balance settings to
