Used four times the shutter the photographer jvc gr-d396us charger to shoot the city at night, because the flow of vehicles, leaving a path of red and white lights, and dozens of light from the light come together to form a long dragon, is very beautiful, bustling city that never sleeps will be portrayed . Or used to take water, shoot the feeling quite soft and delicate.
In the selection of low-speed shutter to pay attention, because each level of the low-speed shutter exposure time difference between the big and not fast shutter 1/250s 1/500s, making it difficult to compare results. Shutter speed in the flow with the scene, if the shutter too quickly, it will not easily freeze the scene; if the shutter is too slow, the overall look is too dim, lost the desired performance results. So try to use low-speed shutter of each cell are patted see, you can get good work, can see the difference lies.jvc gr-d350u charger
Compared to the shutter, aperture to slightly more complex. In addition to the amount used to adjust the exposure aperture, the most important thing is to control screen "depth" in size. The so-called "depth of field" refers to the mediation of the lens focus, can clear the furthest part of the image and the distance between the last part of the range. This is often referred to as a range of depth of field. The longer the depth of field, then the greater the scope of clearly presented; the other hand, the shorter depth of field, the foreground or background will become the more vague and ambiguous because of the formation of a loose focus on obscure phenomenon.jvc gr-d347u charger

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
