The trigger mechanism. Is made entirely of metal and insulating material. In the absence of skills in metal work should be entrusted to a specialist - in whole or in separate parts. The main part (with decorated handles) made of aluminum. Corner - of insulating material. Dimensions shown in FIG. Significantly, the two major axes that serve the connection between the isolated head and push the internal switch, ensure the horizontal direction of the pressure. Attach the trigger cable: it is passed through a drilled hole in the metal part so that it can be screwed in a specially cut for this purpose, the opening device. Button cable is placed in the dug deeper, eliminates lateral movement and provides a uniform vydviganie trigger pin. If there would be displacement of the cable included with the advance or delay. The nest. The distance between their centers - 19 mm, the left socket is connected to a wire coil with a current carrying contact, right - brass gon with the current carrier set screw. The lateral outer walls are made of insulating material. Screws for securing the cutting should be done in the aluminum hull. Freeze protection cover, which covers the current supply quotations screw.
Take a look now with the technique of portraiture. An important role in getting a good portrait is the camera lens. Short-focus wide-angle lenses and almost unusable for portraiture. Exaggerating the future, they are shooting close-ups violate the proportions of the face, increasing the protruding part of the face compared to remote parts. Suitable for portrait photography normal lens, and better long-focus lenses, allowing a close-up portrait of a great distance. Short-focus lenses are not very useful for portrait photography is also due to the large depth of field. It is essential to the background. In portraiture the background to do a neutral, smooth. This helps to blur the background, which is achieved by the use of telephoto lenses with shallow depth of field. From these considerations should not blind the camera. Portraits must be removed with the full aperture of the lens. In addition to a soft image, which improves the picture, the full aperture of the lens can reduce exposure and avoid tension in the pose and the face is removed. Also, when shooting with long shutter speeds are possible shifts photographed. Correction of this deficiency on the negative is impossible. Exposure for portrait photography should not exceed 0.5-1 sec. Portraits should be done only on sensitized plates and film in the normal and high contrast sensitivity. Happy shooting can be done on sensitized plates and film with a yellow filter, for artificial light can be used the same materials without the filters.
