Click tracks are especially useful to modern "one man bands" who may use a multi-track audio editor to perform all or many of the different parts of a recording separately. Click tracks can also aid live bands that want to synchronize a live performance with things like prerecorded backing tracks, pyrotechnics and stage lighting. [1]
Grayscale images are distinct from one-bit bi-tonal black-and-white images, which, in the context of computer imaging, are images with only two colors: black and white (also called bilevel or binary images). Grayscale images have many shades of gray in between.
Binary images are also called bi-level or two-level. Pixel art made up of two colours is often referred to as 1-bit in reference to the single bit required to store each pixel. [2] The names black-and-white, B&W, monochrome or monochromatic are often used, but can also designate other image types with only one sample per pixel, such as ...
An important goal of this adjustment is to render specific colors – particularly neutral colors like white or grey – correctly. Hence, the general method is sometimes called gray balance, neutral balance, or white balance. Color balance changes the overall mixture of colors in an image and is used for color correction. Generalized versions ...
The majority of black-and-white infrared art, landscape, and wedding photography is done using orange (Wratten #15 or 21), red (#23, 25, or 29) or visually opaque (#72) [d] filters over the lens to block the blue visible light from the exposure. Very dark-red (#29) filters block out almost all blue, and visually opaque (#70, 89b, 87c, 72 ...
Later processes moved toward a black-and-white image, although photographers have used toning solutions to convert silver in the image to silver sulphide, imparting a brown or sepia tone. Similarly, selenium toner produces a blue-black or purple image by converting silver into more stable silver selenide. [ 2 ]
The first black-and-white feature film photographed entirely on panchromatic stock was The Headless Horseman (1922). [6] But early panchromatic stock was more expensive, had a relatively short shelf-life, and was more difficult for laboratories to process because it required working in total darkness.
Generally, a Scharnow turn involves 1.) placing the rudder hard over in any direction, 2.) deviating 240 degrees from the original course and then placing the rudder hard over to the opposite, 3.) when the heading is 20 degrees from the reciprocal course, the rudder should be placed amidships and engines stopped to bring the vessel alongside ...
