Lens change

The main advantage of cameras with interchangeable lenses over compact cameras is, as the discerning reader has already guessed, the ability to change lenses. Changing the lens itself is a simple matter and briefly covered in the instructions for any camera. Nevertheless, there are a number of nuances that are not written in the instructions, but which you should take into account if you want to learn how to change lenses quickly, confidently and with minimal risk for photo equipment.

Change the lens should be carried out as quickly as possible. And not only because of the fear of missing out on a spectacular shot while tinkering with technology, but also because of the unwillingness to leave the 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).
