| HOME SUBSCRIBE PHOTOGRAPHERS EXHIBITIONS CONTACT BOOK GALLERY | Sometimes you have to give up shooting interesting spatial composition of a frame built just because not enough alike sharpness of the lens for details of the first and long-distance plans. In such cases, may help the positive zonal lens. Lens in combination with the lens changes the focal length of the system: it increases the negative lens, positive shortens. More likely to use positive supplementary lenses. If such a lens set close to the lens, it is possible to produce macro devices, in which there is no corresponding extension of the lens. Photographing at night is difficult and not always take photos of high quality. Therefore, in some cases, photographers use special techniques when you need photos taken at night. This is called the shooting "at night." Night shots of a dark sky, the low overall tone and increased at intervals of brightness, in the frame if there are illuminated or luminous objects (lights, windows, moon, etc.). In addition, if the day the air is distributed so the prospect of light that illuminated from the air long objects are more light and less contrast, at night due to adaptation of the eye, we better see nearby objects, they seem to be brighter, but in the background, we see only silhouettes. Obtain the effect of night shooting on a sunny day by day by using filters and exposure to light. Pick up an object with deep shadows, and composition of the image building so as to occupy the bulk of the dark or unlit elements. Filming is carried out at the clear blue sky, which through a red filter or a polarization in the picture will become dark. When using polarizing filters to remember that the best effect is obtained by the dark sky when the sun is at right angles to the direction of the shooting, that is, with side illumination. Exposure to light at high brightness range will get the negative transparencies underexposed shadows. |
