Light falling on the photodiodes of the digital camera matrix is converted into an electrical signal. For this to happen, the number of photons that hit each individual photodiode must…

What is bokeh?

Bokeh (English. bokeh; YAP. 暈け or ボケ – “blurring”) is a characteristic of the aesthetic qualities of the image area that lies out of focus, i.e. outside the grip area. Bokeh has nothing to do with sharpness: two lenses that depict objects in focus equally sharply can have a completely different blur pattern, the subjective artistic merits of which are described by the term bokeh.

An ideal lens from an engineering point of view focuses light from a point source in the form of a regular cone. When the tip of the cone touches the plane of the matrix or the camera film, the image is in focus and the photo gets an extremely small point. Continue reading

Light

Light is the heart of photography. The camera does not see the image. There are no lines, shapes, or textures for it. A film or digital sensor is only susceptible to a stream of photons of higher or lower intensity projected on them by the lens.

Light is much more important than the subject, because, in fact, we are not able to see the object as such, but only see the light reflected from it, which allows us to judge the properties of the object. A novice photographer is looking for a subject to shoot, while an experienced one is hunting for light.

The problem is that both good (from a photographic point of view) and bad light are not always obvious to the untrained eye. Continue reading

Exposure settings in limited lighting conditions
Everyone knows that in order to get a good picture, you need the right lighting. However, photographers often have to work in not the most comfortable conditions, when there is…

Good pictures in bad light
Regularly photographing in natural light, it is not difficult to notice that a really good light (not abundant, but good) is a frustratingly rare phenomenon. Let's be honest: beautiful lighting…
