A few years ago, I just started working on SLR cameras. At that time, I was not aware of using a shutter release. Did you hear the tape B door, which is roughly taped around the shutter button to achieve long exposure QAQ
Later, they would not tolerate it any more. Even if they only use the b-door once a year, they will purchase the simplest cable release at Tmall.
But then later on, getting started with photography, has a higher pursuit of the camera, only to achieve a locked manual shutter line then it seems quite tasteless. After it was worthwhile to buy a Xi'an branching rudder, it was time and place for the people to start this aubergine shutter and really free their hands.

â–² Remove the first layer of shutter and sponge pad, uncover the cardboard, the following is the product of the cable and instructions
â–² The shutter body is made of a plastic shell with skin-like material coating. The matte feel is good, but fingerprints and perspiration are easy to leave. The upper part is a plastic injection button and has a blue work light function that can be set in the APP. The lower part is the red light of the switch, which mainly serves as a reminder.
â–² red V-shaped waist line lit the entire front design, making the product's red and black color match the most common red and black color SLR. However, the biggest highlight may be this: the upper part of the product looks like a vest, the lower part looks like a boxer briefs, the lowermost indicator light is...
â–² There is only one data interface on the side of the cable, which can be used with a variety of connection lines to use with different shutter interface machines.
â–² There are snaps that can be inserted into the hot shoe behind the fuselage, and a battery back cover that uses two No. 7 batteries. Because of the use of low-power Bluetooth 4.0, two 7-cell batteries work for six months is not a problem. But there is a problem. After the shutter is inserted, the flash that comes with it cannot be popped up. . .
â–²The manufacturer does not have a battery, so that it can be delivered to the customer faster by considering SF Air.
Then, as a senior friend, you tell me loudly that we don't have batteries for our friends?
â–² The instructions are very simple, connect the shutter release, download the APP is OK. After-sales service in accordance with national standards, 7 days back, 15 days for.
â–² English can't fall on the back
â–² Overall, these two small things, the right plug connected to the camera (Canon 60D), the left plug is connected to the shutter
â–² Contrast with previous shutter
â–² right here, insert the camera plug
â–²The shutter part is also completed
â–² Press and hold the shutter body button for 3 seconds. The red indicator light will turn on. The moment will turn off. The blue work light of the button will blink.
â–² put a open motor
â–² At the end of the figure, you can see that the red and black colors of the shutter are perfectly matched with the SLR.
First scan the box QR code, download the APP, enter the registered account, convenient to save the shooting parameters
â–² After the aubergine shutter is switched on, turn on the Bluetooth, search on the APP, and connect for a moment.
â–² The operation page is very simple, the left side can call out the function bar, and the upper side monitors the shutter power. You can see that there are a lot of functions, there are voice controls, shake the camera, etc., greatly enhance the camera's own operability
â–² The simplest function is a single shot, suitable for close-range remote photography, dragging the time axis can be set to delay, more than 10 seconds can be defined, convenient countdown function enables the machine to leave the operator to take a picture in advance, such as a group photo , creative selfies, etc., can be described as self artifact. Not only is a single shot available, other functions can also be timed to facilitate automatic shooting in an unmanned state.
â–²Continuous shooting is generally used less frequently, but it is more commonly used in latent birding and outdoor sports photography. Manual or automatic continuous shooting function can be used to keep detail in the process of rapid movement to facilitate later screening and synthesis.
â–²B door shooting, should be used more features, is also a common function of the ordinary shutter line, but compared to the general line shutter or the use of 2.4G wireless shutter, Bluetooth audio shutter can shoot starry sky in the cold The endless stream of roadside shooting tracks provide farther operating distance and more abundant operating space.
â–²Time-lapse photography should be the main function of this shutter. You can directly input the shooting interval and number of shots according to different shooting requirements on the operation page. The system automatically calculates the shooting time, and the application is very wide.
â–² If you use long exposure during the day, the ND mirror is indispensable, but for starters, ND is not familiar with the calculations, the shutter provides the ND calculation, easy to use different filters to achieve the shooting effect required for shooting, such as running water, Long exposure shots such as Yun Yong and people flow
â–²B door time-lapse photography is different from normal manual transmission or automatic transmission. It takes more than 30s exposure time, and superimposed into a delay film is generally used in single long exposure, with ND mirror used more
â–²B-curve time-lapse photography should be the progress of the former. In some shootings, there is a need for material with a large span of time, and it is not possible to use the same parameters for shooting. For example, a change in day and night requires a delay in the gradual change. By adjusting the parameters of different shooting time periods, to achieve a normal film in different light environments...
â–² will be switched to landscape mode for easy operation, right to download and save shooting parameters
Shooting sample
▲ There is this artifact in the hand, and the top of the chest is natural. After observing several sunsets, Xi’an’s recent air pollution has been at the forefront of the country, and there has been no desired effect. Basically it is impossible to see, and it is not a bold move. Good weather came no time, there was time to haze days...
â–² Long track exposure at night, experience the actual shutter effect. Bridge exposed coordinates
Summarize the advantages:The eggplant shutter is a type of accessory that takes one place at a time. Whether it is a novice shooter who just started shooting, or a veteran master who shoots more often, they all meet their needs. Especially in creative shooting, the advantages of wireless smart shutters are highlighted. As a high-performance smart Bluetooth shutter, in general shooting conditions, the basic user satisfaction.
The product is somewhat unreasonable in terms of volume and shape. For example, it is easy to get out of the hot shoe, blocking the flash, and the size of the product still has a space to reduce. In addition, the operation of the APP still needs to be optimized, and a few disconnections need to be improved.
Usually,10 & 20 layers PCB are HDI board,but some are not .Some with big trace width and space,holes are over 0.3mm too. We have much experience in doing 10 layer PCB & 20 layer PCB.
A ten-layer board should be used when six routing layers are required. Ten-layer boards, therefore, usually have six signal layers and four planes. Having more than six signal layers on a ten-layer board is not recommended. Ten-layers is also the largest number of layers that can usually be conveniently fabricated in a 0.062" thick board. Occasionally you will see a twelve-layer board fabricated as a 0.062" thick board, but the number of fabricators capable of producing it are limited..
High layer count boards (ten +) require thin dielectrics (typically 0.006" or less on a 0.062" thick board) and therefore they automatically have tight coupling between layers. When properly stacked and routed they can meet all of our objectives and will have excellent EMC performance and signal integrity.
A very common and nearly ideal stack-up for a ten-layer board is shown in Figure 12. The reason that this stack-up has such good performance is the tight coupling of the signal and return planes, the shielding of the high-speed signal layers, the existence of multiple ground planes, as well as a tightly coupled power/ground plane pair in the center of the board. High-speed signals normally would be routed on the signal layers buried between planes (layers 3-4 and 7-8 in this case).
