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
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
For full control over the process of obtaining a digital image, it is necessary, at least in general terms, to imagine the device and the principle of operation of a digital camera.
The only fundamental difference between a digital camera and a film camera is the nature of the photosensitive material used in them. If in a film camera this is a film, then in a digital one – a photosensitive matrix. And just as the traditional photographic process is inseparable from the properties of the film, so the digital photoprocess largely depends on how the matrix converts the light focused on it by the lens into a digital code.
The principle of the photomatrix
The photosensitive matrix or photosensor is an integrated microcircuit (in other words, a silicon wafer), Continue reading
