Invented around 2000, solarigraphy (also known as solargraphy) uses photographic paper without chemical processing, a pinhole camera and a scanner to create images that catch the daily journey of the sun along the sky

LRGB, short for Luminance, Red, Green and Blue, is a photographic technique used in amateur astronomy for producing good quality color photographs by combining a high-quality black-and-white image with a lower-quality color image.thumb|left|Deep View of the Large and Small Magellanic Clouds captured using the LRGB method.In astrophotography, it is easier and cheaper to obtain good quality, high signal-to-noise ratio images in black and white. The LRGB method is used to work around this to get good color images. The color (chrominance) information from the
