Pictures are artistic items of light and shadow, the light is called the soul of photography is not an exaggeration. To take a very good picture, you can not grasp the light of this essential element.
The nature of light
In fine climate, the sun shines directly with no any shelter him becoming photographed, the light side will create a bright tone, not straight affected by the light of a substantial shadow side is formed, this light is referred to as direct light. In direct sunlight, the light-receiving surface will be extremely smooth and without sharp contrast, it is simple to create 3-dimensional.
When the sun was thin cloud cover, the sun will penetrate the clouds diffused lighting contrast developed by this time will be reduced, really suitable for portrait photography.
On a cloudy day, the sun was obscured by clouds, the subject can not be fired straight, or through reflection only exposure to the media on the topic, will create light scattering via the middle, sort of light called the scattered light. Because scattered light receiving surface and formed a shadow side is not apparent, and dark contrast is also weak, modify of light and shadow are more supple, so the impact made comparatively dull soft.
Direct light will produce a powerful contrast between light and shadow resulted in a relatively strong, much less tone adjustments, the video shoot tougher line and tone. The contrast in between the weak scattered light will generate light, so the shadow of light, wealthy tone modifications, will come softer lines and soft tone photos. Therefore, the photographer should be selected for the light beneath diverse situations.
Projected light in various directions
Shoot the identical scene, the use of light in diverse directions projected to produce different final results.
Comes from behind the camera, toward the front of the subject is referred to as cis-ray light. Shun lighting characteristics are: most of them are straight affected by the subject of light, shadow small in size, the object tone clearer. This type of light and dark contrast is weak, 3-dimensional objects illuminated by the main light is not reflected, but manifested by its personal ups and downs. For that reason, three-dimensional weak.
Toward the subject from the camera left rear or proper rear light known as the front light. Most of the location will be affected by light object light, vibrant surface produces huge, so it brighter tone, the object is not a shadow of light will not be considerably, but it has been possible to show the brightness distribution and the three-dimensional shape of the object. Such light can retain reasonably vibrant tone, and can show the subject of 3-dimensional kind.
Light from the left or correct side of the camera called the sidelight. It will be the subject of half the light, and the other half in shadow, is conducive to the overall performance of the state of objects and downs.
As the “edge-lit” lighting makes objects shaded area increases, so the screen does not light not dark tone, light and shade mixed, not as crisp as the front side light generated by the light and smooth, but it will not be too gloomy. 3-dimensional shape performance will be better.
Left front or right front side of the light from a camera known as the backlight. It tends to make a little portion of the object to generate a light getting surface and most of the shadow side, so would be much more somber tone. This strategy of 3-dimensional sense of illumination on an object will generate light greater than shun, but still weak.
Backlighting is behind the subject shot to the front toward the camera light. The vast majority of subjects in the shadows. By contrast the light is weak, so the stereoscopic also weak, comparatively gloomy tone. Even so, the backlight can be utilised to outline the silhouette and contour of the object, you can also emergent texture and shape of the object, clearly show the lines of the object. Use the backlight in bright weather but will generate a robust contrast.
The light comes from the prime of the subject is that of the top light. Midday sunlight is a very good example. Top light frequently lead to sturdy shadows on the subject, if utilized for portrait photography, the next person’s nose and face, eyes, jaw, and so forth. will be formed below the thick black shadows.
A light source located beneath the bottom of a topic. This light is significantly less common in each day life encounter, so it is strange and dramatic impact, in common photographic scenarios hardly ever utilized.
The contrast of light
Contrast refers to the subject of the brightest and darkest tones relationships. The so-known as robust contrast, is the large difference in between the light show in the primary physique of the brightest and darkest components of the internet site and the brightest to the darkest quite dramatic modifications in the conversion procedure, the contrast is really powerful. In contrast, the contrast is weak, the brightest and darkest components of the web site not also massive a distinction from the lightest to the darkest conversion procedure alterations extremely soft, so quite rich tone.
