Capture DV video editing and compression

Make jvc gr-dv800u charger a good film, you can put directly on the DV save, then went with the DV playback machine can also be collected to the computer, the edited record back to DV belt can also be collected to the computer where carved directly into DV AVI files Save up to CDR can also be compressed into MPG, VCD carved or SVCD, DVD saved. MPG is a lossy compression, no matter what format is compressed, the loss of quality there, but the engraved plate MPG or the most common way to save, I think the main is so for several reasons:

1, DV video jvc gr-d750u charger playback performance on the TV is far better than the performance on the CRT, although the CRT resolution is much higher, mainly because the design of television is to display dynamic images, so the brightness, color on both CRT-based display static than better, and the resolution of ordinary television show only 320 lines, then the DV up to 720 × 576 resolution do not need, whether it is the 352 × 288 or VCD SVCD to 480 × 576 is enough So even though there is loss of quality compressed into MPG, but can not see on TV is basically out. In the computer point of view, SVCD resolution is enough clear.

2, DV jvc gr-d396us charger is a problem with the save, after all, tapes, DV is also used with time is not long, but long before the adhesive tape recorder and the mold we have seen in estimates. The CDR disc blue plate, green plate is generally for 30 to 50 years, the gold disk can hold 100 claims, although the CD is also the possibility of mold, but after all much better.

3, the convenience of playing on the disc is strong, DV with DV machines have to move out, but only on television, is also worn on the head, rewind, very troublesome, and VCD, SVCD discs more convenient I do not have to say.

4, then considered a financial account, DV with a box of 25 30, CDR 1.5 a, as I in March to buy machines to now, has carved out about 45 SVCD, CDR cost is less than 70, if into DV tape, probably 30 or so, even with the LP model also 20, which is several hundred pieces ah. 1394 card and now the recorder is very cheap, and bought these two things can do also other purposes.

Acquisition

What to do Well, here is how to do it, and now the DV machines generally have two connected computer interface, one of which is connected serial port or USB port connected, this is generally used in still image capture (some with MPEG1 compressed DV capture via USB port MPEG1 format, but less effective), another is that we use to capture DV video 1394, and stands for IEEE1394, also known as FIRELINE (FireWire), SONY machine called I. LINK the machine is a 4-pin DV small port on the computer 1394 generally is a large 6-pin port.

The first step is to install the 1394 acquisition card (of course, no computer has 1394 this step.) The card inserted in your computer's PCI slot ( laptop to buy an external PC card 1394 card), then boot, WIN98SE, WIN2000, WINXP these operating systems can automatically find the 1394 device and automatically install the driver program. If you find the 1394 card does not work, please put the computer's motherboard drivers and patches installed together, and then try to change it not interrupt or change the conflicting device operating system. Must be made clear is that 1394 cards have different chips, not all 1394 cards are compatible with all motherboards, and generally done earlier because the TI chip, and motherboard compatibility is better, and VIA chips, cards and VIA motherboard, of course their is no problem, but in co-ordination with other board easily go wrong. If the methods are used or not working properly, that is not compatible with the motherboard and the 1394 card. So when buying 1394 card, and businesses that are not compatible with the card replacement or return.

1394 card installed in the device manager to see the 1394 device to work OK. 1394 is hot swappable, but I do not have the habit is the computer off, but DV is off then plug the line, mainly because I think the DV relatively delicate, the computer because it is a clumsy thing, casually toss.jvc gr-d350u charger

Water sports shooting skills

Splashing CANON PowerShot SD600 Charger waves, sunlight sparkling in the bright reflective clothing to generate the body of water activities are exciting intense dynamic body of photographic subject matter. In recent years, water sports is committed to the development of creative use of cameras to provide a number of shooting opportunities.

And the usual way around, moving the body photography CANON PowerShot SD630 Charger does not always need to use long lenses . Is actually fairly simple to use photographic equipment, film planning canoe, drive boats, race boats, sandbars sailing, surfing, jet washed the raft and sports activities, can produce eye-catching photos .

300 mm or longer lens is expensive, and large weight. At the same time, to get good results , long-lens camera in the use of need more accurate than short focus.

I found, in this case is the secret of using a short lens as close as possible subject. Sometimes. This means that to get into the cold water, on your knees shooting. And thus must also focus on prospects for a person who, leaving spectators and other athletes in the background, it is particularly useful.

If CANON PowerShot SD750 Charger a specific sport in a fixed runway, I am usually a good distance prior to the test, select some of the best pre-tune focus. Choose the length of several different lenses to achieve different effects. Remember, water sports to shoot good pictures is not always to use high-speed shutter, fuzzy little pictures can often convey a strong dynamic subject, and the whole site can not have a clear picture. However, to master the use of this technique have to find out how much blurring is just right, it is best to appreciate from the practical experience to master. This technique also depends on what you shoot is sports, the length of the lens focal length used, and dynamic camera angles and the size of the body. Shutter speed below 1 / 60 seconds, the result is difficult to predict, but it has an advantage that can capture beautiful pictures with special effects, these photos are almost like a oil paintings. When using a longer exposure, the camera is placed in a stable tripod, shooting pictures out of the water looks beautiful.

Another technique is to use 1 / 125 second or even faster pace, to follow the photography CANON PowerShot SD550 Charger . Taken this way out of the picture, the subject is quite clear, but the background will show the fuzzy stripes. To make fast flowing water Ning Zhu, usually transferred to at least make the shutter speed 1 / 500 sec.

Especially when using longer lenses when shooting fast moving objects, in order to accurately focus is very difficult. The problem can be a point on the subject focus or follow pre-focusing to resolve. The former technique is simple and suitable for different situations. The latter technique is more difficult to master, but also to constantly adjust the focus to the subject matter can be clear when approaching or leaving. If you use an ordinary spiral focusing lens, until you feel there is no master of this technology to conduct training.

If you are using a 200 mm lens focal length or longer, more technical training to be a. It should be noted is that if you are using a different manufacturer's lens, then there is the lens to focus the sub-clockwise. Some counter-clockwise focus, then we should make sure you use all the lenses are focusing in the same direction. Otherwise, the height of the movement, you can be able to focus the direction of confused, missed most valuable shooting time. Should have a sports photographer, the most important skill is the ability to anticipate the peak action. Cartier-Bresson called it a "decisive moment." Ability to identify this peak is taken by your campaign to be carried out thorough and careful observation and accumulated. I realized that, to sit down calmly, to be taken on the kind of idea photos carefully. Before shooting and the problems may be estimated to be crucial. This does not make you shoot some documentary photos. You can also draw a few sketches before shooting, you expect the effect to get some discretion, which is particularly useful work.

In my view, mental preparation and selection of at least as important as the appropriate photographic equipment. Mentally ready to not only help you capture the scene of the accident, but also allows you to overcome the harsh environment encountered difficulties. Even with or without boots and umbrellas on the success or failure has a great relationship. Sometimes carrying a camera, the camera is waterproof cover to prevent water splashing or immersion. Indeed. A professional photographer is best to buy a sturdy waterproof cover, if you do not often use, you can buy a very cheap made of polyethylene and flexible waterproof cover. I find that both durable and waterproof cover is not easy from the floor. On one occasion, shooting rapids in the Zambezi River red raft movement, my camera to escape calamity.

Now to talk about how to determine the correct exposure. Unfortunately, the automatic TTL exposure meter is easy to light reflected by the water shortage caused by the exposure. When transferred to the ideal position polarizer, the polarizing filter can reduce the reflected light in some nasty, but also increase the color saturation. In addition, you can use a handheld light meter to measure incident light readings taken, take back of the hand can measure the reflected light readings; press 1/2-2/3 file to increase exposure. If you use a polarizer, do not forget to increase the required exposure compensation. (Increase of 1 / 3 block) by manual adjustment TTL exposure meter measuring the reflected light readings taken back of the hand, you can also get the same effect. If your camera's CANON PowerShot SD500 Charger light meter can only be controlled, you can compare the hand and features readings, and then adjust the exposure properly. In this case, exposure compensation is no longer needed because the polarizer to the lens has already been installed on the.

Life skills in photography mode

Real canon bp-608a battery life itself is extremely rich. People in his spare time, to conduct a variety of activities , such as learning, rest, recreation, housework and so on. People in different occupations, there are different ways of life of the same sex who have different hobbies. These colorful real life photography provides a wealth of material. Photography life forms is also very lively. Life photography and industry, agriculture, sports, theater and other photographic different, it is not more restrictions, shooting very free, no rules, and generally free time , environment, climate constraints.

Life Photography General requirements:

1. To reflect the performance of real life photography is the life of the true story, this is real life. Although real life is an objective reality, but it is a natural form of things, good and bad mixed, beauty and ugliness exist, so what happens in life, reflected in the photo up, ideological, should be healthy.

2. To reflect the spiritual outlook of life, photography and other types of photography canon bp-412 battery, is never one of the activities. Specific activities by people, to reflect the people's living conditions, recording people's life experiences, it reflects the human spirit is very important, but also to shape the spirit, some live photography, I saw people that appearance, but no figures of the heart, This work is neither a true record, still less the value of art.

3. Have a strong flavor of life must have a strong photographic life breath of life, it and other photography is different. No breath of life works, the contents of dry, dull image. Therefore, we must learn to capture candid shots of the lens, should not pretentious, and fraud.

Life Photography Practice:

1. Photo shoot photographs of life in common is the photos of "all" is this type of photo. Various types of cameras canon nb-5l battery can shoot a photo. If possible, put the camera on a tripod stand, in order to slow down, reduce the aperture to increase depth of field. Before filming, the subject order should properly focus on the good, but check it at the people with the most recent figure is by far the depth of field with the aperture range. Ready, the subject immediately prediction: "Note, ready to shoot!" Meanwhile, observe the demeanor of the subject, waiting to press the shutter.

Shooting points: First, use side light, dark, according to the Ministry of the face exposed ; Second, suitably small aperture, long depth of field; Third, people should not be too wide arrangement of the characters the same line of sight requirements.

2. Whether shooting pictures of people Xiaozhao elderly, youth, or child, should reflect their good features, characterize their external form and internal psychology. Light, composition, tone processing, from person to person should be.
Pictures of people using the standard lens or a telephoto lens. Telephoto lenses can not pay attention to the case of the subject, grab an air of nature.

Shooting points: First, the light can be used side light, side of the backlight, the backlight; the second is the depth of field should be short, focus should be real; third tone processing, the person, because the situation varies; Fourth, pay attention to posture, to promote capture.

3. Take family photos of these photos, but also good choice lens. People should pay attention to emotions when shooting, not mercy, not contrary to real life.

Shooting canon nb-4l battery points: First, we must work hard to refine the theme, atmosphere and theme of the environment fit; second, to scenes of realistic situations; The third is to screen a lively, strong breath of life; Fourth, make full use of on-site source, appropriately fill light; fifth aperture , speed, and flexibility.

Five digital camera shooting techniques

1. Mastering flash photography
Best to use the automatic flash mode, the camera automatically detects the environment, to achieve the best shooting conditions. If you are in the indoor and outdoor camera flash, then the performance of some digital cameras CANON PowerShot SD110 Charger CANON PowerShot SD200 Charger CANON PowerShot SD300 Charger CANON PowerShot SD400 Charger have improved significantly, but not necessarily to shoot a good effect. For example, in the room or backlit situations encountered during the day, such as the sun sets, the background is a landscape of neon light, strong, can still use the flash to fill light, the light hit the subject area so as to avoid making the image out of a black embarrassing results. But you have to be sure that you index the hands of digital camera flash, flash range is generally in the 0.5-3 meters, depending on which digital camera should have a different range. Otherwise than this range, may cause flash invalid. If it is close-up shots, such as between 15cm-20cm, select the force does not flash, or easily overexposed.

2. To avoid facing the light source shooting
Taken to avoid facing the light source, with particular attention to the light source is from the glass, metal or other smooth surface reflection surface of the water came out, to ensure that the image is clear. You can try the digital camera to a fixed reflector, such as in the case of open flash shooting CRT monitors, digital cameras let you get a condenser of the light point. And the image regardless of how your computer graphics software, they can not make any original photo image restore. So solution is to avoid the light, changing the position or to close the photo flash, if the source is insufficient, please reinforced by other sources.

3. Adjust the aperture shooting fireworks
If you want to shoot fireworks in the evening, because the light was insufficient, so large or can be first transferred to the maximum aperture, shutter transferred to 1 / 15 ~ 1 / 30 seconds. Because the benefits of digital cameras is that you can take lots of pictures, as fireworks fleeting moment are the scenery, you may wish to take more than usual, the more experimental, to shoot the beautiful fireworks.

4. Adjust the ice shooting small aperture
As the snow reflects the sun will produce light, often into the background according to the bright, the result of the face but secretly. Therefore, in camera, the aperture to narrow the point. You can also use flash directly to the target person's face, so character and background brightness will be the same, making the target more clearly, and to reduce the reflection of light.

5. To avoid large areas of the same color view taken
As a result of the impact of pixel and sampling, the current digital cameras can not distinguish between color too thin. For example, a black dress, the effect of light and shadow, the black color can be divided into hundreds of black, digital cameras, this can only be divided into 24 or 36 black species, with gap between the real scene. Therefore, in order to shoot good photos, the best subject to have both smooth and clear contours, such as portraits, cars, buildings and so on. That is, to clearly separates foreground and background to make the image more vivid.
