Studio Display video camera gets bad reviews, Apple promises system upgrade

Last week, Apple announced the Studio Display. Although it has not yet been released, the first criticisms have been issued. One of the shortcomings of the video camera is that the picture quality is very poor when measured, and some reviews even compared with the old BlackBerry phone, the lens performance is extremely bad.

The Studio Display is equipped with a 12MP ultra-wide-angle video lens, coupled with the built-in A13 Bionic processor, the outside world expects the video lens effect to be comparable to that of the iPhone 11, but media reviews pointed out that the Studio Display video lens effect is not only distorted, but also lacks detail and is full of grain. Reviews say the Studio Display video camera performs poorly in good light, especially in dim light. The above situation does not improve whether it is connected to a Mac Studio computer or a MacBook Pro laptop, even if the Center Stage function is turned off or turned off when using FaceTime, Zoom, Photo Booth.

An Apple spokesperson said that it has been informed of the Studio Display video lens problem, and said that it will be improved through a system update later, but did not say where the improvement was, and did not say when the update will be determined.

Common prosperity is not rich! Lens Technology predicts that net profit will drop by 50%

Lansi Technology, a major Chinese mobile phone glass manufacturer, recently announced its 2021 performance forecast. It is expected that the net profit attributable to shareholders of listed companies in 2021 will be 2.007 billion to 2.399 billion yuan, a decrease of 59%-51% compared with the same period in 2020. The reasons include power cuts, shortage of materials, research and development of new products, and response to the “common prosperity” advocated by the Chinese government.

In response to the earnings recession in 2021, Lens Technology listed seven reasons in its earnings forecast. The first is that power cuts have a certain impact on the production delivery and operation scheduling of orders. For example, some factories in Hunan, Taizhou, and Dongguan were forced to temporarily suspend production due to power cuts. The established production and delivery rhythms were disrupted, and employees were lost, resulting in yield fluctuations and rising costs. Production and delivery could not be completed in a timely manner according to the original plan. Task.

The second is to actively respond to the national “Common Prosperity” initiative. Since September last year, the salary standards of grass-roots employees have increased, and labor costs have increased; in addition, power cuts and production shutdowns have increased employee mobility, and company management costs and labor costs have increased additionally .

Third, after the acquisition of the Kecheng Taizhou factory, it was originally regarded as an important key to breaking into the Apple supply chain. However, Lens Technology said that with the completion of the asset delivery of the Taizhou Park, the strength of its metal business has been greatly enhanced; however, due to the low proportion of direct recruitment in the workforce structure of the Taizhou Park, there are many R&D projects newly established by customers. Labor costs and R&D expenses have risen, affecting profitability.

The fourth point is that due to the new two new parks, Huanghua and Xiangtan, which have been put into operation, the new factory, new production line, new team, etc. need to be run in for a period of time, the initial operating cost is relatively high, and the product structure is mainly based on new products, research and development. The investment is relatively high, the cost of recruiting staff and labor costs increase, so there is no benefit in the short term.

Fifth, Lens Technology pointed out that due to the strong demand for research and development of new fields, new technologies and new products from downstream customers, such as watches, VR, AR, new automotive glass, and smartphone middle frames and other metal alloy products related The significant increase in R&D projects and R&D expenditures will have a certain impact on the short-term business performance.

The sixth point is that the new crown epidemic and the global dual carbon policy have led to a shortage of raw material supply for industrial products and a sharp rise in prices, which has increased procurement costs and has a negative impact on profitability. At the same time, the new crown epidemic has led to the gradual intensification of the contradiction between supply and demand of chips and semiconductors, which has caused some customers to ship less than expected.

The last point of impact is that due to the resurgence of the new crown epidemic, the overseas business typical of Vietnam parks will continue to be affected in the second half of the year. Factors such as logistics obstruction and supply chain epidemic prevention and control have affected the production and delivery of orders.

However, Lens Technology emphasized that despite new difficulties and challenges such as repeated epidemics, limited power consumption, and supply chain shortages last year, the company took effective measures in a timely manner to keep production and operation generally stable; Business, smart terminal complete machine assembly business, and photovoltaic new energy business and other medium and long-term development strategies have continued to make progress.

Learn these 7 simple tricks to take good photos with your phone

Mobile phones have become a part of everyone’s life, and the shooting functions are getting stronger and stronger, and some are even close to traditional SLR cameras. With the convenience of mobile phones, photography is no longer limited by equipment, and you can shoot anytime, anywhere. But there are also some tricks to pay attention to to take good photos with your mobile phone. Today, let us learn the following 7 points to pay attention to!

(1) Clean your phone lens
One of the serious problems of mobile phone photography, which is often overlooked by novices, is that the mobile phone lens is very easy to have oil stains on it, which will destroy the quality of the photos! As a necessities of daily life, mobile phones are used very frequently, and the camera lens of the mobile phone will be soiled if you are not careful. Fortunately, modern phone lenses are also usually easy to clean. You can remove oil by swiping with a dry cloth or the corner of your clothing before shooting, but only if you remember to do this before shooting!

(2) The mobile phone should also focus accurately
Just like a traditional camera, your phone needs to focus! If your focus is inaccurate, there is a chance that the photo will be out of focus and blurred. Focusing on the phone is very simple, you just need to tap the position you want to focus on. If you want to do a camera-like AF-Lock function, you can just long press (in the case of an iPhone) and the phone will lock the focus point.

(3) Manually adjust the light and dark of the photo
If you compose the shot and press the phone to shoot immediately, the photo will automatically meter for you and automatically set the shutter and ISO, just like in fully automatic mode. However, in some clear situations, such as white snow, black caves, or framing with sky, the metering of the phone may be wrong, then you need to manually adjust the light and darkness of the photo to make the photo have accurate exposure . The iPhone pulls up and down next to the four boxes after focusing, while Android usually has the option of “+/- EV” directly. Students need to find it in the mobile phone camera app.

(4) Keep the phone stable
Have you ever noticed that the photos taken by your mobile phone are blurry? One of the reasons is that the phone is not stable enough and moves during the exposure process. To keep the phone stable, it is best to hold the phone firmly with both hands, or put it on/rely on a fixed object, or even put it on a tripod dedicated to the phone, which can reduce the chance of blurred photos.

(5) Take a shallow depth of field
As long as you understand the shooting method of shallow depth of field, the mobile phone can definitely produce the effect of “clearing in front and behind”! For modern mobile phones, there are two main ways to shoot shallow depth of field. One is the “traditional method” like a camera; the other is to use the “portrait mode” to let the mobile phone do post-processing. Now let’s review the shallow depth-of-field method of a camera:

How to Get a Shallow Depth of Field

Traditional method (for any mobile phone)

  1. Large aperture (assuming the phone cannot change the aperture)
  2. Long focal length (assuming the phone has only a single lens and cannot optically change the focal length)
  3. The distance between the background and the protagonist should be farther

1 and 2 can be adjusted in traditional cameras, but not many mobile phones on the market. Therefore, in order to take a shallow depth of field effect, the most important point is the third point – “the distance between the background and the protagonist should be farther”. Remember to use the mobile phone to open the shallow depth of field, the mobile phone should be as close as possible to the protagonist, and the farther the protagonist and the background are, the better. You also have the opportunity to move the angle of the mobile phone to adjust the distance of the background.

Portrait mode method (depending on whether the phone has this function)

Just set the phone to “portrait mode” and shoot directly. But if your phone doesn’t have a built-in portrait mode, you’ll need to shoot the traditional way!

(6) Turn on the grid of the phone
Most mobile phones also allow you to open the grid in the photography app. It is recommended that you open the 3×3 grid. This can effectively implement the “rule of thirds” composition, and can also be used as a counterpoint function, so that the photo can be kept horizontal, which is very important and convenient for photographers who have requirements!

(7) Find interesting angles
One of the great advantages of mobile phones is convenience. Convenience comes in handy when looking for compositions! You can hold your phone at high and low angles, or jump over a railing and place your phone out of the camera’s reach to shoot, so your chances of finding interesting angles are greatly increased. Therefore, when using a mobile phone to shoot, remember to change the angle to increase the composition change.

5 Myths About “Macro Lenses”

For macro photography, many amateur or professional photographers are also addicted to it, but for many beginner photography friends, the subject of “macro” is relatively unfamiliar, and there are often many misunderstandings about “macro lens”. Here are 5 pairs. The myth of the macro lens, see if you can answer the question in your mind?

(1) The macro lens is only used to take macro photos
Of course, a lens called a “macro lens” will be very competent when taking macro photos, but a macro lens is not necessarily only used to shoot macro works, but many photographers also use it to shoot other subjects. , such as portrait photos, and many macro lenses also have better contrast and saturation.

(2) Macro lenses are expensive
It is undeniable that the original macro lenses are often more expensive than ordinary lenses, but in fact, there are many high-quality macro lenses from sub-brands such as Sigma, which are often only half the price of the original, which is more suitable for amateur photographers or novices. Calculate it!

(3) The maximum aperture of the macro lens must be f/2.8
Many friends also feel that if the maximum aperture of a lens is not f/2.8, the lens is not good enough. In fact, for macro photos, unless the subject is at some distance from the lens, the f/2.8 aperture value is not commonly used because the depth of field becomes very shallow. And when shooting macro, even f/8 aperture can make beautiful bokeh, not necessarily f/2.8!

(4) The longer the focal length of the macro lens, the better
Generally speaking, for macro shooting, the focal length of the lens is more suitable in the range of 50-70mm. Of course, when taking pictures of some small insects and small animals, the distance will be too close to scare them away. At this time, a longer focal length is required. But it should be noted that the longer the focal length, the higher the stability requirements of the camera, so many photographers will also use a tripod to shoot macro works.

(5) You must use a macro lens for macro shots
Many novices have never tried to shoot macro works, because they think that they must use a macro lens for macro photography. Of course, a real macro lens is also more convenient for imaging and convenience, but in fact, beginners can use some accessories such as close The camera ring, macro tube, etc., with the existing lens, you can also take beautiful macro works, and these accessories are not high-quality, very suitable for students who are just starting to play!

8 Improper Uses of Photography Filters

After shooting for a period of time, students will often use different filters, such as polarizers, gradient gray, etc. But sometimes because of the first contact, I don’t know much about the usage and characteristics of various filters. Some mistakes will be made, which will make the result of shooting unsatisfactory. Or something weird happens. Here are 8 wrong usages of filters, don’t make them again after you learn them!

Photo from

(1) Gradient Gray Filter: Incorrect Gradient Position
Gradient gray filters are gradients from dark to transparent, allowing you to balance light differences (such as taking photos of the sky during the day). When you use a gradient gray filter, remember to always check the gradient position. Especially when you change the angle or zoom in/out, otherwise the light and dark levels of the photo will look weird.

It is recommended to use the glass gradient gray filter of FGEARS in the United States, which is one of the best filters on the market! Available at GearSuggest®, the official Fotobeginner store.

(2) Gradient gray filter: the gradient is too obvious
There are two main types of gradient gray filters, “Hard” and “Soft”. You can choose different types at different times. Hard is mainly used when shooting coastal sunrises and sunsets. And Soft will be used in general. However, when using the two filters, you must also pay attention to whether the gradient will be too obvious. So please use the appropriate degree and variety of filters. Don’t blindly pursue high-level filters or use too many blocks together.

(3) Polarizer: used in (ultra) wide-angle lens
Polarizers are useful in landscape photography. It can not only eliminate the reflection on the water surface and green leaves, but also make the blue sky bluer. But be careful, the blue sky must be in the other direction of the sun, otherwise it will not have an effect. Therefore, if you use a wide-angle lens (especially a wider ultra-wide-angle lens), the shooting range will have the opportunity to extend from one side of the sun to the other side, resulting in a dark blue at one end of the photo and white at the other end (due to sunlight). There is a chance that the effect will be worse than not using CPL!

(4) Polarizer: do not reset after changing the direction
Polarizers need to be adjusted before shooting. If you shoot from horizontal to straight, you must re-adjust the polarizer to get the effect, be sure to pay attention!

(5) Adjustable ND filter: black cross appears
Now many manufacturers have also launched “Variable ND Filters”. The advantage is that the degree of dimming can be adjusted at will according to the environment and needs, avoiding the trouble of carrying multiple ND dimming filters. But if you adjust too much, the photo will have unsightly black crossovers, which can be solved by being careful not to overshoot the adjustable range.

(6) Do not keep the filter clean
Most of the filters are installed in front of the lens and have a direct impact on imaging. If your filter is full of greasy dirt or dust, it may cause problems such as unsharp photos or dust spots. So remember not to ignore the cleaning filter!

(7) Use of poor quality filters
Many novices are also greedy to buy low-quality filters to use. In fact, a good filter can be used for many years, taking thousands of photos for you. Poor quality filters are mostly unsatisfactory in terms of workmanship, light transmittance or coating color. It makes the photo prone to color cast and sharpness drop. And cleaning is mostly not easy due to the lack of an effective coating. Therefore, it is recommended that students start with a better filter if they have enough budget!

(8) Using the wrong size
Whether it is a round or square filter, we also need to use it with different lens sizes. If the filter is too small it may not cover enough. Filters that are too thick also have a chance of black corners when using a wide-angle lens. You should pay more attention before purchasing.
