Sharpness
Is sharpness important for a good photo? Yes and no. On the one hand, technically perfect photography, as a rule, should be absolutely sharp. No matter how entertaining it may…

Macro shot

The word “macro photography” usually means photographs taken on a sufficiently large, but still not microscopic scale, i.e. from about 1:10 to 1: 1. Pictures with a scale exceeding 1: 1 are already referred to as microphotographs, and everything smaller than 1:10 is considered just a close-up. The given ranges of scales are very arbitrary, and can serve only as guidelines, and not in any way rigid boundaries between individual genres of photography.
Perhaps the reader does not quite own the concept of scale, and the numbers 1: 1 tell him little about what? There is nothing complicated here. The shooting scale is the ratio of the linear dimensions of the subject to the linear dimensions of its image projected by the lens onto the matrix or film. A 1: 1 scale means full-size Continue reading

RAW or JPEG?

The electrical signal generated at the time of shooting by the matrix of a digital camera enters the camera processor as an array of digitized, but not yet processed or, if you like, “raw” data. This data is then either recorded without further processing on a memory card in the form of a so-called. RAW-file, or pre-processed by the camera processor, which forms a full-fledged image on their basis and saves it in JPEG format. JPEG photos are the final product of the photographic process and are fully suitable for viewing, printing, publishing on the Internet or any other practical needs. Pictures saved as RAW files must be edited in a special converter program, which allows you to convert raw data provided by the matrix into a graphic image in JPEG or TIFF format. Shooting in RAW is used in cases where the photographer for one Continue reading

Capacity

The bit depth or color depth of a digital image is the number of binary bits (bits) used to encode the color of a single pixel.

It is necessary to distinguish between the terms bit per channel (bpc – bits per channel) and bit per pixel (bpp – bits per pixel). The bit depth for each of the individual color channels is measured in bits per channel, while the sum of the bits of all channels is expressed in bits per pixel. For example, an image in the Truecolor palette has a resolution of 8 bits per channel, which is equivalent to 24 bits per pixel, because the color of each pixel is described by three color channels: red, green and blue (RGB model).

The fight against laziness and time management for the photographer
Let's not forget that many photographers are now giving their clients photographs in indecently long periods. I will not quote wedding clerks who give out albums after 9 months, when…

What is the focal length?
The focal length (FR or ƒ) is the distance between the optical center of the lens and the camera sensor. The larger the focal length, the larger the image scale…
