Features of color correction in Photoshop
The work of the color corrector mainly consists in processing images (and other material) that are being prepared for output to devices. Often, processing causes a lot of problems for…

Basic settings of the camera
I recommend that any novice photographer actively use the camera's automation whenever possible. This applies to matrix metering, autofocus, automatic white balance, and everything else that can only be automated,…

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…

Selecting the optimal aperture

The ability to effectively use an existing lens has a much greater impact on the sharpness of the photo than the choice of the lens itself. The aperture number is the most important of the shooting parameters that affect the technical quality of the image. The difference between different aperture values of the same lens may be much more noticeable than the difference between different lenses at the same aperture.

Aperture f / 1.8 f/1.8
Aperture f/2.8 f/2.8
Aperture f/4 f/4 Continue reading

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

Color balance
The colors of objects that we see are not a property of the objects themselves, but a property of our vision. Grass looks green only because light rays reflected from…

A little theory
White balance is an important tool for managing the color palette of a photo. One of the advantages of a living person over a digital camera is that a person…

The strategy for choosing the optimum diaphragm
Find the aperture value at which your lens shows the best sharpness, and use this value whenever possible (most often it is f/8 or so). If you don't have enough…
