Each component can take any value between 0 (black) and 1 (white). For example, if each component takes a value between 0 and 1, the total range of possible colors is 0 to 255. When these three numbers are added together, the resulting number represents the light's intensity. Each R,...
Hue, saturation and brightness, or HSB, are aspects of color in the red, green, and blue (RGB) scheme. These terms are most often used in reference to the color of each pixel in a cathode ray tube (CRT) or newer display. All possible colors can be specified according to hue, saturat...
most types of data can be stored in my spreadsheet including numbers, text, dates, images, videos and more. some spreadsheets also include features allowing you to track changes over time by data visualizations such as graphs or charts. how can i use my spreadsheets? spreadsheets can be used...
A pixel is just numbers representing a color of a dot at a location in the image. Pixels are how a digital image reproduces a scene and its colors. The camera lens creates an image. Then to reproduce that image digitally (numerically), the digital camera sensor merely takes millions of...
Axial chromatic aberration, also called longitudinal chromatic aberration, often occurs in images made with wide apertures (low f-stop numbers). It can be corrected using the Defringe sliders in Lightroom 4.1 and later. Add chromatic aberration for a unique look. ...
RGB is another color model based on the combination of the primary colors — hence, the shorthand for Red, Green, Blue. RBG color codes are composed of three numbers separated by commas. Each number represents the intensity of the respective primary color as an integer between 0 and 255. ...
I have a large table in Excel that includes the columns "Desk" and "Date". I would like to highlight all rows where there are duplicate desks per...
Hexes are just a different way of writing RGB values. Something like#6a79f7(cornflower blue) maps directly torgb(106, 121, 247). 6a is thered, 79 is thegreen, and f7 is theblue. First, you should know that in the hex color system the letters “a-f” represent the numbers ten to...
Higher numbers (5,000K to 6,500K) produce cool, bluish-white light, like noon daylight. Understanding color temperature helps create natural-looking images or deliberate mood effects. Photographers and filmmakers use this concept to control how colors appear. For example, indoor lighting is typicall...
Gray cards and the "middle gray" term may be 18% reflectance, but the common opinion is that the mix of colors in many scenes average closer to K=12.5. Because, the RGB Luminance is Luminosity = Red x 0.3 + Green x 0.59 + Blue x 0.1. Brightest Green reflects about 59% of the ...
