See also Magnitude.Īspherical Lens – A lens with flattened edges, useful for a clearer, sharper image.īak-4 Glass – Premium, high-density barium crown glass that minimises internal light scattering so the images seen through these lenses are sharper. Using this system, stars can also have negative magnitude values, and these are the brightest we see in the sky. Therefore, a star that is three magnitudes less than another is (2.512) 3, or about 16 times brighter. The difference between the apparent brightness of two stars follows a logarithmic ratio of 2.512. The combination of internal reflections and optical refraction provides the double reflection to make the image on your paper right-side up and correct left-right.A B C D E F G H I J K L M N O P Q R S T U V W X Y ZĪltazimuth Mount – This usually refers to telescope mount which allows movement in two directions: azimuth (horizontally) and elevation (vertically).Īperture – The diameter of the binoculars’ or scope’s objective lenses, measured in mm.Īpparent magnitude – This refers to how bright the star appears to the naked eye. Your brain superimposes the two images into the appearance of a ghost image of your subject onto your paper. The upper part of your view looks into the prism. When you place your eye close to the edge of the prism, the lower part of your view sees the paper. There have been different prism configurations over time, but each split-pupil prism design works the same way:

The NeoLucida Plus uses a prism to split your vision between a view of your paper and a view of your subject. The NeoLucida Plus prism is based on the very first camera lucida design created by William Hyde Wollaston in 1807. The optical arrangement is a setup where you see straight through to your paper with a reflected ghost image of your subject superimposed. The NeoLucida Plus, like the original NeoLucida, is a “split-vision” camera lucida design. How it Works: NeoLucida Plus, a Split-Vision Camera Lucida Click here to learn more about why, and how NeoLucida might help. Want to learn more about the camera lucida? Check out our History section for more. Learn more about the NeoLucida from the Kickstarter campaign here. The NeoLucida was launched in 2013 and was supported by 11,406 backers on Kickstarter. Instead of a complicated tool with delicate, finicky parts, the NeoLucida is simple to set up and robust enough to toss in your bag for artists and designers on the go! The NeoLucida is inspired by a long history of optical drawing tools, modernized using 21st century manufacturing and materials. You can also see your hand, so you can trace from real life. How does it work? The NeoLucida prism acts like a beamsplitter when you look down into the eyepiece, you see a ghost image of your subject on your paper. It is a modern reinterpretation of the camera lucida, an indispensable tool popular in the days before photography was invented. The NeoLucida is an optical drawing aid that lets you trace what you see. Tools like the NeoLucida might help getting started a little less frustrating. Armed with a little knowledge and a lot of practice, I believe anyone can learn to draw. Reviving historical art technologies that help people draw, in order to:ĭemystify drawing and explore how people-past and present-learn to draw.ĭrawing accurately from life is not a superhuman ability reserved for 'gifted' artists. So what is The NeoLucida Project all about? Despite high resolution smartphone cameras in our pockets, people like to draw, and a lot of people have the desire to learn to draw. As a modern reinterpretation of the camera lucida-a 19th century optical drawing aid-the NeoLucida is part of a rich history of drawing technologies aimed at helping people draw.Īs someone who likes to draw, and has drawn consistently since I was little, I was surprised by how many people were drawn to (pun intended) these tools I make. Both the NeoLucida and the NeoLucida XL are simple technologies that may make learning to draw a little less discouraging, and perhaps a little less intimidating. Even if you’re good at it, drawing can still be frustrating.
