Factors affecting bokeh

The number and shape of aperture blades
The arrangement of the lens aperture affects not so much the quality of the blur as the shape of the blur circles. In fact, so-called blurring circles rarely have a perfectly round shape. They usually look like more or less regular polygons with the number of sides corresponding to the number of diaphragm lobes. The aperture in Nikon lenses has 7 or 9 lobes, in Canon lenses – 6, 7 or 8 (occasionally 9). The more petals there are, the more rounded the blurring disk looks, and an odd number of petals usually produces polygons that are more pleasing to the eye. Continue reading

Exposure: theory

Good exposure is critical for getting high-quality photos. However, the essence of the exhibition is very simple. Exposure is just the amount of light that hits the photo sensor. The process of shooting a frame is sometimes called exposure.

The exposure can be reduced or increased. That’s all you can influence. A smaller exposure makes the frame darker, a larger exposure makes it lighter. A lack of exposure is called underexposure, and an excess is called overexposure.

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

Can I fix the errors later?
As for the exhibition, no, you can't. Overexposure is not allowed in digital photography. Even if you shoot in RAW, the capabilities of RAW converters (contrary to the assurances of…
