What is the difference between an amateur camera from a professional one? Present days in the development of photographic equipment there has been a significant jump forward and it is very complicated to determine the differences between amateur equipment and a professional one. Purchasing a camera, each beginner draws primarily attention to the cost, then the manager tells him briskly about the benefits of this particular camera, but in the end will show where to direct, where to look, where to press and it will be sufficient for an amateur. Next he will photograph his friends, girlfriends, etc., without hesitating that the portrait is one of the most complicated photo techniques.

So, the major difference of professional cameras from amateur ones - is a wide selection of settings that help ensure a high quality of stills. It is such features as: the ability to alter the objective, shutter speed, frames per second, the length of exposure, manual control of adjusting the exposure, automatic bracketing; nowadays there are cameras with the ability to snapshot in HDR mode.

Types of viewfinders.

The viewfinder is destined to target the camera on photographed objects. It shows what will be on the photo in cases when the boundaries of the still are not determined on the diffusing glass (the camera does not have frosted glass or photography is executed not from a tripod).

Viewfinders are framework and optical, which are divided into cross-cutting, mirror and electric.

The most convenient are framework viewfinders: you may hold a camera at eye level that contributes to a more customary reproduction of visual perspective.

This viewfinder consists of two frames: small and big in the format of a negative; they are separated from each other by a distance equal to focal distance of the objective дуты. The framework viewfinder gives a still in its life-size and very comfortable for viewing.

The mirror optical viewfinder consists of two collecting lenses, one of which is smaller, located vertically, and the second, larger - horizontally in the upper part of the viewfinder; among them at the angle of 45 degrees to both lenses the mirror is attached which reflects the upward rays passed through a smaller lens. Ultimately, large lens forms an inverted mirror image of your object of shooting.
