Wide-Angle Lens for Digital Camera broader perspective

 Digital cameras with wide-angle lens and camera, as the main purpose is to expand the shooting range. For example, in a small space or small room, with wide-angle lens to the lens can not solve the ordinary footage.

 Digital cameras with wide-angle lens, a strict should be called "Wide-Angle Lens," because the so-called "Lens" attached to the original only in the lens. Different digital cameras to attach a different angle lens, such as home digital video camera lens diameter 37 mm, 43 mm, etc., professional <digital camera lens with 52,58,72 mm and so on. Wide-Angle Lens models the manufacturers are not the same identity, such as Panasonic's 4307, that can be attached to the 43 mm digital camera lens, the wide-angle multiple of 0.7 times the original lens that can shoot the scene 70% smaller , equivalent to the original lens range 1.43-fold. Sony and Panasonic is different from its wide-angle lens attached logo and Panasonic just turn, such as 0637 table 0.6 of its wide-angle multiple times, can be attached to 37 mm lens on a digital camera to use.

Using wide-angle lens attached, although you can expand the shooting range, but there are some image quality loss. Such as digital cameras with wide-angle lens attached, the four corners of the screen will be a slight blurring, if wide-angle lens without hood, very prone to faint light, like Sony's 0637 consumer-grade wide-angle lens is simply no additional installation hood of the interface, so, if not very need, the use of wide-angle lens attached should be cautious.

Why digital camera DV function will take time limit

Using digital video cameras we found that many models in the continuous shooting time is limited, why is it so? Let's analyze why.
One reason is the storage format issues
Most of the digital machine is that the memory card formatted with FAT32 format, FAT32 only supports 2GB maximum single file. For digital camera images, a single file larger than 2G may be small or non-existent this problem. But for continuous shooting video, its a single video file size is directly related to shooting for a long time, when the continuous shooting time is very long, single file will be larger than 2G, so the camera will automatically stop recording, you need to press next record button to start a new file.
In fact, the situation in the use of digital camera memory card also, but the vast majority of cameras in a single file than 2G, it will automatically generate a new file to achieve a continuous record. In fact digital cameras should also be done automatically generate a new file feature, but manufacturers do not do it, such as Canon 7D, etc. can be recorded continuously for a long time.
 The second reason is the product tax issues
It is said that the foreign products for cameras and camcorders tax is not the same, lower taxes cameras, camera products, high taxes, the product is defined as a continuous camera recording video 29 ​​minutes 59 seconds for the sector, higher than this time as a camera products, not lower than this time. Some cameras have video recording capabilities of the product, if its video recording features over 29 minutes will be charged higher taxes, so in order to avoid multiple taxation problems, let the camera can record video in 29 minutes time control.
Whatever the reason, the camera is continuously recording the video should be able to do limited time, or set time limits on human factors. In addition, the camera is the camera, if you completely replace the camera, it is estimated the manufacturers still do not want to do that.

Video capture tool for one of Panasonic GH2 Introduction

Panasonic DV for people who play are not familiar with, and today we talk of a digital camera is the Panasonic GH2, in our "digital cameras", said digital camera feature seems to be some "stray," but we are talking about today Although the GH2 is a "camera", but it's "camera" function is very powerful, let's find out.
 GH2 is not a "lonely one" is actually the predecessor in GH2, Panasonic has a model on a similar product for the GH1, GH1 in mainland China but this is not for sale. But even without selling in mainland China, and in the shop in a physical store, this model is not uncommon, we buy this "camera" and a big reason, is optimistic about its HD video recording capabilities, so we Taobao to find if there is a lot of GH1. Now GH2 after birth, Matsushita to this product are sold to the Chinese mainland.
 GH2 GH2 although its origin and history more powerful camera, but its position is digital camera, instead of the camera, its origin is micro 4 / 3 system. In fact, 4 / 3 system is the sensory area of ​​the image transfer is 4 / 3 inches, the standard was first born in Olympus, and later because of the development of DSLR, 4 / 3 system marginalized. The lybs cooperation with Panasonic, a new standard of "micro 4 / 3", because the lower body weight and other reasons, so that 4 / 3 are again light. GH2 appearance, let us see the power of digital cameras in the camera's powerful.
 Panasonic Panasonic GH2 advantage in the video still has a comparative advantage in particular the latest high-definition video format AVCHD encoding technology, and Panasonic cameras over the years of production experience, the video recording technology, "grafted" to the digital camera is not difficult things, this may also be GH2 HD video shooting in a relatively strong performance of the main reasons. As the predecessor of the GH1 GH2 to everyone's surprise, not born to be sought after GH2. The main advantage of GH2, or it comes to home video recording capabilities, and enhance the function of another, such as the unique continuous auto focus, interchangeable lenses and can record multiple video formats.
Please pay attention: video capture tool for introduction of two Panasonic GH2

Using the remote control to determine the failure DV

Now virtually all of the appliances are equipped with remote control, whether it is TV, DVD player, air conditioning, DV, etc. Almost all of the appliances are inseparable from the remote control, especially now that a lot of flat-panel TV unit with only one power switch, or just take in a simple key, the vast majority of TV functions, remote control will need to achieve, therefore, an increasingly important role of the remote control if lost or broken remote control, really trouble. We often encounter with a bad case of the remote control, but very difficult to determine the remote control is not a problem, in the end is the battery is dead, or have other problems? Now to tell you about using a DV camera to determine the quality of the remote method.
First, we turn the power DV, the DV into the shot (camera) mode, then the suspected problem on the remote control transmitter, which is often said that the remote control in front of the face in front of a DV of electrical camera, press a button while watching the LCD screen to see DV on the remote control transmitter has no "little light" in flash, if you can basically determine the normal remote control, remote control battery is also no problem. If the transmitter's no "little lights" lit or flashing, indicating the remote control problems, such as the battery is dead or the power contacts have bad problems, you can clean the battery compartment and replace the battery of electric shock to try a new battery. Similarly, if the remote control of one or a few key failure can not be used, this method can also be used to judge.

In fact, the remote control press the function key, the transmitter emits infrared light to be sent to the remote device control information, but we can not see infrared light, but DV can "see" infrared light emitted by remote control, so We use this principle, with the DV to see the working status of the remote control to determine whether the initial failure. In fact, really a lot of the usefulness of DV, to see how we use and use it.

Universal (GE) DV1 is a toy or DV

Recently, the production of aircraft engines boss cited General Electric Company (GE) out of a DV product, the model is called to do DV1. I do not know the reason because the world economic downturn, or something else, so GM is adding to the manufacturing industry to the DV. In fact, as far as I know GM's a lot of things, ordinary incandescent bulbs products have a common figure.
 DV1 special features
 DV1 SD card or SDHC card to record, too, and many similar products, the largest expansion of support for 32GB of storage. This little machine has a special East this comparison can, for example, in water depth of 5 meters safety, fell to the ground from a height of 1.5 m will not affect the shooting, also has industrial-grade dust. These features can be said is basically a "weather", and is really God, into the earth, the water is too difficult to learn. We can carry DV1 go diving, you can also put the DV1 on the beach, can also be used when the "hammer" ... of course, no one will come as a hammer to use with DV, but fell to the ground fell from 1.5 meters is not bad, if used in times of crisis people smashed head is no problem, at least not worry about DV will be broken.
 Looks like a lot of toys or can also
This is known as full HD this waterproof, anti-collision flash camera Mingzi called DV1, the words name does not have HD, but it can take a 1080P Full HD models, but from the very simple name. HD camcorders with 5.08 million effective pixel CMOS image sensor, 2.5-inch 230,000-pixel LCD screen, built-in USB connector, HDMI high definition output. From the chart we can see, this little thing with a USB plug their own, can not turn on the cable directly into your computer.
 Pictures and video recording format, and other
Record all kinds: static pictures 5MP (4:3) .3 MP (16:9) 8MP: 3264 × 2448, 5MP: 2592 × 1944, 3MP: 2048 × 1536, 2MP: 1920 × 1080, 0.3MP: 640 × 480
Video Recording: 1920X1080 30fps; 1280X720 60fps/30fps; 1440X1080 30fps; 640X480 30fps
The DV may be a variety of colors, look a bit like a relatively large head phones, and even "long as" a bit like a "cottage" goods. General DV1 has the ability to capture full HD video, each video recording time is 29 minutes. Why is this machine that the maximum recording time is 29 minutes? This in another article to explain.

Tripod in the camera's magical

Household are more compact and lightweight camera, tripod camera can be used according to their size of a proper election can be. Of course, the large number of relatively stable tripod of some, but its weight can not be ignored. If you do not ask, choose a small tripod tens of dollars you can. Buy a tripod must check whether the lock fastened, the head part of the left and right and up and down the rotation is smooth, not ebbed and flowed.
Use a tripod self: a tripod camera can not only shoot a stable image, self-timer can also be used. If we go out to play, can carry a tripod and camera remote control, so you can easily put the camera frame is completed, they used remote control cameras to shoot and zoom, then the camera's LCD screen can be flipped open and 180 degrees, so you can watch and take it easy.
 Film-like picture: many of the film camera will blur out the background or foreground to highlight the subject. We use a tripod to steady the camera can also shoot a similar shot, let the camera zoom in times of state, the shooting of the film blur the background or foreground effects to make the picture better mood.
 Candid weapon: more people in the shooting scenes such as the wedding ceremony, we all stood up to meet new people when you can lift the tripod to the camera is much higher, as they stand on a ladder, like to shoot, so you can easily photographed and shot less than others do not see the scene.
 Cater to stick with: travel hiking when tired, if you can easily stick some of the root, then fold up the tripod can be used as both a walking stick and rest when you can carry items to hang.

Three models of the pure 16:9 16:9 frame

With the popularity of flat-panel TVs and home of a large number of high-definition DV market, flat-panel TVs are 16:9 aspect ratio, which everyone is familiar with. New high-definition DV, because the high-definition video recording format, aspect ratio is 16:9, so for shooting high-definition DV format aspect ratio setting, the choice items can also be ignored, use the default settings. However, the previous standard definition format, digital cameras, and can take into account both SD and HD models can record it, you also need to understand some other aspects of knowledge about 16:9, or may be because the wrong setting, resulting in shoot out Before the video aspect ratio with the desired effect is inconsistent and bring regret.
 Divided into three modes 16:9
 16:9 is to capture and record video frame aspect ratio is 16:9, because our topic is "digital camera", so we are not at a 16:9 TV that thing, only that in the end when shooting digital camera to choose what kind of shooting modes, is shot to shoot 4:3 or 16:9. First we need to know, in fact, for the HD and SD cameras, the set of their film frame ratio in three ways: First, the pure 16:9; second extrusion 16:9; third masking type 16:9.
 Pure 16:9 mode
The so-called pure 16:9, about two situations: First, high-definition DV video shot in HD format should be pure 16:9. That is, if we use a high-definition format, digital camera, shooting video is HD format, that regardless of their record high-definition format, which, like the 1080 or 1920 * 1920 * 1280 * 720 and 1440, These videos are seen in the flat TV screen is normal 16:9 format. Second, the so-called standard definition format in pure 16:9. In fact, not in high definition will have a "pure 16:9 mode", there are pure SD 16:9 mode, the SD 16:9 we will in another article.
We can understand the following resolution 16:9 full-HD or pure, standard Full HD 1920 * 1080; HDV format 1920 * 1440; HD 720P standard 1280 * 720. The standard video resolution of the resulting "pure 16:9 mode", a digital camera can record standard TV formats and can play, there are some non-standard 16:9 we can not say.
