Lens device

The lens should be considered a key component of an optical device called a camera. That’s right: not a matrix, but a lens. A photograph is an image, and nothing more than a photographic lens forms this image on a photosensitive material. The matrix only converts the image created by the lens into digital form.

A photographer does not have to be an expert in the field of applied optics, but having some idea of ​​how the lens of your camera works will not only not interfere with your creative growth, but will also help make photography more conscious and manageable.

Lens aberration

Aberration of a photographic lens is the last thing a novice photographer should think about.

Nevertheless, if you do not know what to take your time, reading this article will help you understand the variety of optical aberrations and methods of dealing with them, which, of course, is invaluable for real photo-erudite.

Aberrations of the optical system (in our case, the photographic lens) is the imperfection of the image, Continue reading

Scatter Circle Size

A scatter spot (circle) is a distorted image of a point projected by a photographic lens onto the camera’s matrix or film. These distortions are caused, firstly, by structural factors, i.e. natural imperfection of optics and photosensitive material, and secondly, functional reasons, and above all – selective focus. An image of an infinitely small point can be a point only when it lies strictly in the plane of the matrix or film. If the image of the point is out of focus, the point turns into a blurry spot of rounded shape, the size of which increases with distance from the plane of the ideal focus (see also “Bokeh”).
