The basic use of flash techniques

Speaking of what a flash, the general photographers jvc gr-hd1 charger often have a misconception that the flash light source is used in low light the dark of the occasion, such as night, indoor and so on. In fact, Flash is a very useful auxiliary lighting, good use of a good flash light photography can greatly enrich the language, get a multiplier effect. For example, in people under sunny with a backlit scene, the characters or side light, fill light is often the method can be used to reduce light ratio and contrast. There are two ways to fill light, one is to use reflectors for fill light on the main characters, but more trouble, carry reflectors nor the most convenient alternative is to use the flash on people or close advisers fill light, it is more the ideal choice. Easy to carry because of the flash, color temperature and its color temperature close to the sun, both to improve the tone picture, but also to obtain more satisfactory color effects. Here to ISO100/21 ° film as an example of ways to use flash fill light. First metering (or estimate) the sun exposure combination of background, such as f/11, 1 / 60 seconds, then loaded on a flash, and flash the flash power index (assumed to be 16) divided by the predetermined aperture factor or 16 (index) ÷ 16 (aperture) = 1 (m). At this time in the 1m people at the subject with a flash, the jvc gr-dv3 charger exposure just right. This is just a direct shot, very bright flash and the sun, the sun backlighting may dilute the effect and cause the direction of the unity of light. The correct way is to let people around 1.5m away from the camera, so that the effect of relatively weaker flash, backlighting can achieve both effects, there are dark-level best results, sometimes because the composition of the needs of people want to come nearer, the characters a little bigger, you can cast a flash on the white handkerchief in one or two (depending on distances and fill light intensity may be), weakens the flash of light to fill the role of closer. To use the fill light attention to the question: in general the usual center of the shutter the camera viewfinder, the shutter speed set too high some will not have a negative impact on the flash; but but-lens reflex cameras, the shutter speed is not flash sync speed than the specified otherwise, fill light may produce uneven situation. Flash exposure is mainly from the flash index, shooting distance and aperture decisions. Flash not only suitable for use in low light, dark, light can also be used as a variety of other auxiliary lighting. Auto flash easy to use, fast, but also should pay attention to some practical skills. In order to avoid the formation of a positive flash "red eye" effect, some of the camera flash mode also has a reduced "red eye" feature. Indoors using the flash, not only can light a dark object, but can also use the advantages of high-speed flash, freezing some sports scene.jvc gr-dv500u charger

How to shoot landscape photos with the art of charm

According to what is art?

In fact, very difficult to shoot landscape photography jvc gr-dv3 charger . Not only need to find a natural beauty, but also appear at the right time, weather and light with just right. Most of us do not have the patience.
Some landscape photographers working in the field of art photo. According to what is art? A metaphor is their ultimate goal is to design a room wall. Art photographer, from commercial constraints, free to be creative. They can pursue personal world, and many people choose the form of black and white photographs.
This paper introduces the idea of ​​more on specific skills.

Why is the black and white photos?

When we look at a scene, I saw the color of the world. Black and white coat color photos stripped, leaving only the intrinsic nature. Features in the landscape, such as rocks, trees and mountains, have become the light and shade, texture and contrast to build up the composition elements. Beautiful black and white photographs. Photos into an interpretation of beauty, worth a thousand words. We see from the picture is the artist's vision, in addition, the landscape itself, there are emotional reflection.jvc gr-hd1 charger

1. Travel

The reality is that most of us do not have good luck to live in scenic areas. Therefore, using the holiday to travel only advantage of this is that we will see with fresh eyes to everything.
I will never forget the first time to the Andes, all the way through the remote towns and villages and valleys. Filled with spectacular views all the way, I took hundreds of photos. The experience of the memory will always follow me. Below is my second trip in a photograph:

2. Local

 

On the other hand, local, or short of the landscape, which means you are more familiar with here. You understand it more deeply, we can find no ordinary tourists to the secret location. You can also have to shoot throughout the year.
This and the first point of contradiction? A little. But between the two are not entirely mutually exclusive. Most people will make use of free time each year for travel, other times to stay in one place. Below is a photo shoot in late spring season. This will be one of my favorite season, only a few hundred meters from my house.

3. Light, content and composition

I took photography as a triangle. An edge is the content, the other side is a light and composition. A good photo with excellent light, composition and content. These three are equally important and indispensable. With good lighting and composition are not as good as the content of boring pictures of three sexy photos forever.
Landscape photographer of this mean? You need to find the most beautiful scenery. They can be very spectacular (such as the Andes), it can be a calm beauty (such as the woods near your house), but they must be beautiful.jvc gr-dx77us charger
Then you need to find the best composition and light, to give your own thoughts the landscape. The landscape to what you have emotions? What kind of composition and light able to pass that feeling to your audience? If you can find the answer, you have become a great landscape photographer was.

4. Landscape character

Not only the most beautiful natural scenery photos. People live and work in nature. Good photo contains stories and themes. People living in the landscape is a good theme. For me, the travel is very easy to do this, probably because I see everything is fresh.

5. Remains

In the natural landscape of human activity in the left mark. Although not everywhere, but many places will have a human construction of buildings, walls and roads, trees and rivers as a part of nature. When the man-made elements with time, after washing, it will become a beautiful scene, perfect to be a part of the environment. JVC Battery Charger

Correct understanding of actual digital camera aperture and shutter

Is the camera jvc gr-hd1 charger lens aperture can be changed in the middle of the pore size of the mechanical device, the shutter is the length of exposure time control device (mechanical or electronic), a combination of both, jointly controlled exposure.

For jvc gz-mg21u charger example, the light is like water, the equivalent of a lens to control the flow direction and flow of a sluice holes. Is a hole the size of the aperture, the shutter is a gate opening time.

Gate opening time is fixed, the smaller the hole, the less the amount of water inflow, whereas the more. When the shutter speed is constant, the appropriate aperture (eg f5.6), exposure of normal, the aperture is too large (eg f2.8), overexposed, photographs (positive after washing, not the film) to shining white one, there is no hierarchy, and even a white one; Aperture too small (eg f11), underexposed, photos, a dark, low-light parts of the loss or no-level image.

Hole size is fixed, the longer the gate opening, the more water flows, whereas the less. Therefore, when the aperture is fixed, the right shutter speed (eg 1 / 250 second), exposure of normal, more full of the shutter (for example, 1 / 60 sec), the longer the exposure, overexposure, the faster shutter speed (eg 1 / 1000 second) under exposure.

Note that, although able to control aperture and shutter exposure, its effect is not equivalent. The smaller the aperture, the higher the concentration of light to reach the film (or CCD) imaging, the easier it is clear imaging, (of course, the aperture is too small, there will be diffraction, but fuzzy) the greater depth of field, the smaller the contrary. So, when you need precise control of depth of field, you can first determine the aperture size, shutter speed and then decide. When shooting moving objects, if the shutter open too long, moving objects in the film (or CCD) of the different parts of the image, pictures are not clear, of course, on the contrary, when the shutter speed is high, move the body on film imaging has no apparent movement, the exposure process has been completed, photos to clear, that is, to move the body frozen in the screen, so when shooting moving body, you can select shutter speeds as fast, and then adjust the aperture, correct exposure. Of course, if you want to move the body in the photo on the left trajectory, enhanced dynamic, you can choose a slow shutter speed.jvc gr-d796 charger

Flash photography is particularly important, proper choice of shutter and aperture, you can better control the light flash and other light than that. As is now widely used in electronic flash flash time is very short, only about a millionth of a second, so when the shutter speed to synchronize (the so-called synchronization, is to make the flash of the time fell on the shutter fully open, close the period before Otherwise, do not flash when the shutter is fully open, or closed, the flash does not make sense, even in the film as part of the exposure, recording failure) after a further period of exposure time and no effects. Therefore, the effect depends on the flash to control the aperture, continuous ambient light (such as night lights in the other) depends on the role of the shutter to control, proper choice of the exposure combinations, can create the perfect artistic effect.jvc gz-mg30u charger
