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

Lens device

The lens should be considered a key component of an optical device called a camera. That’s right: not a matrix, but a lens. A photograph is an image, and nothing more than a photographic lens forms this image on a photosensitive material. The matrix only converts the image created by the lens into digital form.

A photographer does not have to be an expert in the field of applied optics, but having some idea of ​​how the lens of your camera works will not only not interfere with your creative growth, but will also help make photography more conscious and manageable.

Diffraction

Diffraction is an optical phenomenon that limits the sharpness of a photograph while reducing the relative aperture of the lens. Unlike other optical aberrations, diffraction is fundamentally unremovable, universal and equally common to all photographic lenses without exception, regardless of their quality and cost.

Diffraction can only be seen at 100% magnification. Notice how the image becomes less and less sharp with increasing aperture.
With the passage of light through the aperture, the bulk of the light waves continues to move rectilinearly. However, those waves whose path lies near the very edge of the diaphragm deviate from their original direction, trying to go around the obstacle that has arisen on their way. The smaller the size of the aperture Continue reading

How to use autofocus
Autofocus or autofocus for most photographic scenes is the preferred solution over manual focus. In skilled hands, autofocus focuses more precisely, and, most importantly, faster than the average photographer. However,…
