Indication Of Use Of Light Meter

How do you light it up for this purpose? To achieve this typical field light effect, use your reflection light meter to take readings of the portions of the strong light or the midtones, rather than the shaded portions. In so doing, you are actually making the image less exposed. You don't get enough light in the shadow part of the film to produce details there. Results: In the film, the shadow part is not detailed, in the photo, whether it is in color or black and white photographs, the shadow part of the black.Light Meter

If you use a gray card, the truth is the same. First, according to the normal method of reading, and then use the surrounding light, that is, the aperture to receive a small block or two-block exposure, so that the image exposure is insufficient. However, the use of color film, slides should be cautious, can not be too much of the aperture. The danger of making the color film less exposed is that you may get a nasty slant. No one likes the picture of Green face! If you use color film, our suggestion is to follow the film exposure rules to expose the strong light part. Then, in order to get a light effect on the scene of the slide, only the aperture is small one block.Light Meter

The scene may be too dim to use the incident light meter to take readings. So what do you do? For this very dark landscape, many professional photographers will take readings of bright white objects: a piece of white paper, a white handkerchief, and a Kodak Gray board. Then they turn the aperture around in half. Why the sophomore? Because their light meter is tuned to 18% shades of gray to reflect. White objects reflect about 90% of the light reflecting about five times times. As a result, they measured up to five times times the reading from the white object, which was too bright.Light Meter

By opening a sophomore block, they can regain the readings they have obtained by measuring 18% ash. Now they have the readings they need for normal exposure. The "normal" exposure will reproduce the dark feeling of the original scene as the scene was initially irradiated by faint rays. Results a photo with field light effect was obtained.Light Meter
