Diffraction
Diffraction is an optical phenomenon that limits the sharpness of a photograph while reducing the relative aperture of the lens. Unlike other optical aberrations, diffraction is fundamentally unremovable, universal and…

White balance

White balance is an important tool for managing the color palette of a photograph. One of the advantages of a living person over a digital camera is that a person sees white objects as white regardless of the color of the light source due to the color constancy inherent in human vision. Forming a visual image, our brain uses not only directly the signals of the photosensitive receptors of the eye, but also information about the type of light source, as well as our knowledge about what color this or that object should be. A digital camera is much more primitive, but it comes to the aid of the ability to adjust the white balance. This is a parameter with which you can change the color of your photos in accordance with changing lighting conditions. White balance is needed in order to tell the camera which of the subject under given lighting conditions should appear in photographs of a neutral tone, i.e. white or gray, and the camera, in turn, shifts all other colors so that the color balance (the Continue reading

Shine

Light is the heart of photography. The camera does not see the image. For him, there are no lines, no shapes, no textures. A film or digital sensor is susceptible only to a stream of photons of a greater or lesser intensity projected by the lens on them.
Light is much more important than the subject, because, in essence, we are not able to see the subject as such, but only see the light reflected from it, which allows us to judge the properties of the subject. A novice photographer is looking for a subject for shooting, while an experienced photographer is hunting for light.

The problem is that both good (from a photographic point of view) and bad light are not always obvious to an unprepared eye. Our brain does an incredible job so that we can see the world around us in any light. People are used to this and forget that the camera is designed much more primitive than our vision, and this must be taken Continue reading

Man and camera see the world differently

Often a scene that looked attractive to our eyes appears completely unpresentable in the photo – with a whitish, illuminated sky, with black dips in the place of shadows, with surreal color shades. What is the reason? Why can’t the camera simply take and display the scene as it is? She’s actually trying. Due to its modest capabilities. The problem is that we ourselves never see the world as it really is. Our eyes and brain do tremendous work so that we can admire the surrounding reality. The camera does not know how, and you have to think for it, perform non-obvious and not always natural manipulations to get images that look natural.

Central and peripheral vision

The field of view, susceptible to detail, is very small – about three degrees. You will be convinced of this if you hold your eyes on a letter in this text and try to look at the surrounding letters without moving your eyes. As you move Continue reading
