Light - is the main tool the photographer. With the light we literally livingwell health club draw a picture. Soft portrait of a woman or a picture of a man with a hard light, sunset sky, or a lunar landscape - the choice of lighting for 80% of your success depends on the frame. In previous articles we have talked about the color temperature of light, direction of light, the laws of distribution of light and the nature of light. In this article, let's look at features livingwell health club continuous livingwell health club and pulsed light sources.
Constant light sources emit light continuously, ie during a time of constantly livingwell health club illuminate the subject. By constant sources include natural daylight and artificial light from incandescent lamps, electrical appliances, lights, fluorescent lights, special videosvet, studio continuous light sources, etc.
Pulsed light sources also emit light only for a short time (for a split second) on the team photographer. Switching power are all sorts of varieties livingwell health club of flash units - built-in and external on-camera flash, studio impulse candy bars.
Switching power can be for a thousandth of a second to give the amount of light needed for the image on the CCD camera. While to obtain livingwell health club sufficient light amount by the constant sources typically require livingwell health club more time for their work. Depending on the intensity of light, this time can range from bright thousandths of seconds to tens of seconds in the afternoon when shooting night scenes, dim lights, stars, etc.
So, the main difference between continuous and pulsed light sources in the nature of their work. This difference gives rise to features livingwell health club and shooting with constant and pulsed light. With constant light more or less clear and simple - all photographers begin to shoot primarily with a permanent natural livingwell health club light.
1. The main parameter livingwell health club of the exhibition, which regulates the amount of direct light - this is an excerpt. Of course, the shutter speed is working closely with the aperture and ISO. But the important thing is that when dealing with a constant source at the photographer's almost no limit on the value of the exposure (except for restrictions associated livingwell health club with the appearance of shake-shake and blurring when shooting motion). It can be set arbitrarily short when shooting in bright sunlight, for example, livingwell health club or an arbitrarily long - to record the movement of the stars.
2. You can make a frame at a time with the confidence of 99%, which is a constant source will shine as he shone a moment ago. During the time of the permanent sources may slightly alter the light intensity and color temperature, but usually it occurs gradually, allowing the photographer livingwell health club to adjust to the changes. The only exception - is the bright sun on a cloudy day, which it turns out, it goes beyond the clouds, resulting in significantly changing the nature of light.
3. There is a possibility even before pressing the shutter button once to see and appreciate the nature of light, black and white drawing and the final form that will take the subject in the photograph.
4. If a constant light source of natural origin, then you are limited in the management of its power and direction. Shooting with natural light - is adapting to the lighting conditions. Options may be different:
1. "Light" can take full control and power, livingwell health club direction, character, width, flux and sometimes even ask to adjust the color temperature using the nozzles.
2. To work pulsed light sources need electricity. If we are talking about the usual external flash units, the problem is solved by the purchase of batteries or accumulators. But with studio monoblocks on the road will have a little more complicated - in addition to the devices themselves, racks and sotfboksov you have to drag the generator and connect devices to it. And the more sources and the longer the shoot, the more expensive and harder to be a sort of "battery" to exit the studio. When shooting indoors, of course, problems with access to the power does not arise.
3. Switching Power with extremely short pulse can freeze the motion even on "
