Other phonesMany other Android phones also offer excellent tools for capturing a lunar eclipse. Most modern Android devices come with a dedicated Night Mode, which you can typically access by swiping through the camera modes or selecting it from a menu. Night Mode helps enhance low-light shots by increasing exposure time and reducing noise. Thankfully, on many phones, any built-in Night Mode will activate automatically when low lighting is detected.

One of the goals of Modular Design is to minimize coupling between Modules (i.e. interactions between modules). Complexity increases with every introduced coupling. And uncontrolled coupling makes it harder to reason about the system. Yet we need modules to interact, because putting everything into one procedure is not an option. Interactions just need to be kept reasonably low.
Another way to approach the linear combination is to look at it geometrically. This is where the idea of barycentric coordinates can help. A barycentric coordinate system describes the location of a point as the weighted sum of the regular coordinates of the vertices forming a simplex. In other words, it describes a linear combination with respect to a set of points, where in -dimensional space.
