How do you look at the photo data?
There were many ways to view the photo data (EXIF data): - ** Computer **: Many software can be viewed. Right-click on the photo and check the "Attributes" to see some information. - ** Phone **: - Some phones had a viewing function. - You can use the Weixin Mini Programs to view it. The following steps are as follows: Open WeChat, click "Find", click "Mini programs", enter "Exif Search" in the search box, click the Mini programs that you found, and then click "Choose Picture". Choose the photo you want to view in the photo folder on your phone, and the Exif information will automatically appear. However, it was best to view the original photos. The Exif information might not be found in the photos that had been adjusted later. - If you didn't need to see very detailed information, you could open the photo in Snapseed and click on the "i" in the upper right corner to see some simple information. In addition, you can also use Canon's Digital Photographer Professional (DPS) software to view the EXIF data and open the "Information" box of the software. You can also further view and edit the EXIF data and XMP and ITPC information. There was also the "photo information view" software, which could display various information including the file size, resolution, time taken, software used, camera used, and location of the photo.

The risk of recovering camera photo data
The main risks of recovering camera photo data are as follows: 1. ** Data Overwrite **: If new data is stored on a reformat storage device (such as an SD card), it may cause the lost data to be overwritten, which will increase the difficulty of recovery. 2. ** The risk of data recovery integrity **: Even if you use professional data recovery software or services, you cannot guarantee that all lost data can be completely recovered. 3. ** Time and cost risks of data recovery **: It may take a long time and a high cost to recover offline data, especially when the equipment has a serious malfunction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The data of the DSLR photo when reading the post
If it was referring to the data related to the DSLR photo, the following were some common ones: ** 1. White Balance ** 1. ** Blue Darkening **: The white balance can be adjusted according to the surrounding light. It is usually set between 4000K and 5000K of CT color temperature. When the surrounding light is warm, the photo taken will not be blue. 2. ** White balance when adjusting different tones ** - When taking photos of different styles such as rich warm colors, blanched colors, low saturated natural colors, premium blue, warm colors, and so on, the white balance can be adjusted according to your personal style. - For example, when taking a photo of a character and Li Hua, the white balance was set to automatic (in the Li Hua shooting example). ** 2. Compensation for exposure ** 1. ** Quiet Gray **: It is recommended to lower the value. It is more suitable to have the value between-0.3 and-1.0. 2. ** Rich and Warm Colors **: Adding exposure compensation can make the photo look fresh, and lowering exposure compensation will make the photo rich. 3. [** Bleached Color **: Can be adjusted according to personal style.] 4. ** Low Saturation Natural Tune **: Adding exposure compensation can produce a refreshing feeling, and lowering exposure compensation can produce a gentle tone. 5. ** Warm tone (when shooting portraits and characters 'skins)**: It is recommended to increase the exposure compensation by 0.7. 6. ** Black and White Film **: Adjusts the appropriate exposure compensation according to the surrounding light. 7. ** Daily Film **: Increase exposure compensation to give a refreshing feeling. 8. ** Pear Blossom Shooting **: The exposure compensation is set to +3 to make the pear blossom photo bright (because the pear blossom is white, increase the exposure to prevent the white balance from identifying the white color). ** 3. Other Data ** 1. ** D-Lighting **: Normally turned off. It is recommended to use high-dynamic HVR in high-light environments (take multiple photos with different exposure and then combine them, but the color may be distorted). 2. **M (Manual)**: If you are traveling or taking photos, try not to use M. Use A (Aperture priority). In A, you only need to adjust the aperture, and the machine will automatically adjust the shutter speed to reach Ev balance, reducing the situation of undershooting or overshooting. 3. ** Metering **: During the day, you usually use range or central evaluation measurement. At night, it is best to use spot measurement. 4. ** USB (Light Speed)**: - The higher the value, the faster the shutter speed, but the noise would increase. - 400 during the day, 1600 indoors and above, and 6400 at night. 5. ** Aperture ** - The larger the aperture value, the smaller the actual aperture. The larger the aperture (the smaller the value), the more light reached the mos, the faster the shutter speed, and the large aperture would produce a shallow depth of field (the background blurring was strong). - Aperture was calculated based on the human eye 1.0. - When shooting scenery, the aperture was usually between F8 - F11, and the close-up was around F4. 6. ** Focus ** - The smaller the focal length, the larger the scene, and the larger the focal length, the smaller the scene, and the smaller the depth of field, the easier it was for the background to blur. In addition, if the photos taken by the DSLR camera were gray (due to inaccurate contrast, camera tolerance, and other factors), in post-processing (if it was taken in raw format), you could use the relevant operations of the Histogram to adjust, such as adjusting color levels, curves, RAW filter, sharpening, and so on. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Data analysts and data analysts
Data analysts and data analysts were both related to data processing and analysis, but there were some differences in responsibilities. ** 1. Data analyst ** 1. ** Job responsibilities ** - He was responsible for the technical management in the early stages of the project, controlling the data processing process during the project, constructing data analysis models, and assisting researchers in data analysis and mining. - For example, in the job requirements of Guangzhou Zero Data Technology Co., Ltd., it was required to have a more comprehensive participation in the data-related work of the project, from the early stage to the management and technical support in the process. 2. ** Basic Requirements ** - Usually, bachelor's degree is required, and major in statistics or applied statistics is preferred. They needed to have relevant data analysis and mining work experience, master data analysis tools, love data work and have the spirit of research. At the same time, they also needed to have good communication and teamwork skills, as well as strong ability to withstand pressure. 3. ** Skill Requirement ** - It emphasized the full participation in the project data work process, and had certain requirements in data-related technology. It focused on basic analysis and mining work, and had certain responsibilities for the technical management of the project itself. ** 2. Data analyst ** 1. ** Job responsibilities ** - Data analysts in different industries specialized in collecting, organizing, and analyzing industry data. They also made industry research, assessments, and predictions based on the data to provide recommendations to decision makers. - For example, the data science team in the ByteDance Management Office (docking the TikTok business) should have a clear understanding of the TikTok ecosystem, and make data-driven business decisions by analyzing user behavior, author supply, and platform ecological output business cognition; Build business analysis or machine learning models and continuously optimize them; Carry out data report presentation and data product design; Meet the data needs of the business side and the team; To provide data support for strategic decisions. 2. ** Skill Requirement ** - They needed to have a deep understanding of the industry and be able to dig out valuable information from industry data for research, evaluation, and prediction. In addition to basic data analysis skills, they also needed to have the ability to build higher-level business analysis or machine learning models. They also needed to closely link data with business decisions to provide a basis for high-level decisions such as company strategies. 3. ** Current Development Status and Requirements ** - In the current job market, companies were constantly demanding data analysts. In the past, you only needed to master some basic tools such as Excel and SQL database to get a good job. However, by 2024, in addition to basic tools such as mysvl and Python, you also need to understand statistics, data cleaning, modeling, algorithms, and other knowledge. Moreover, more and more enterprises and institutions required data analysts to be certified (such as CDA certification). At the same time, due to the trend of digitizing basic positions, the competition for data analysts was more intense. If they wanted to stand out in this position, they had to be in the top 5% of the practitioners. "When a programmer meets a psychologist" is equally exciting. Everyone is welcome to click to read it!

The Future of Data Analysis and Data Engineering
With the acceleration of digital transformation, the demand for data analysts and data engineers continued to increase. All industries valued the value of data. From retail to finance, from medical to manufacturing, data applications were everywhere. According to a market research report, the demand for data-related positions will increase by 20% per year in the next few years, which means that they have a broad career development space. However, the stats analyzer profession also faced some challenges. On the one hand, a large number of job opportunities were concentrated in cities such as Beijing, Shanghai, Guangzhou, and Hangzhou. These cities were filled with talent and the pressure of competition was high. On the other hand, with the popularity of artificial intelligence and machine learning technology, companies had higher requirements for data analysts. Not only must they have solid data analysis skills, but they also needed to master machine learning algorithms to deal with complex data sets. Moreover, after more than 20 years of development, many products and operating methods of the Internet have become increasingly mature. Many companies 'businesses have stabilized, and the demand for data has fallen back to "looking at data" to maintain operations. The problems that need to be solved through data analysis have drastically decreased. In recent years, technological development has spawned many data analysis and operation tools, which have lowered the threshold for product managers and operators to use data. Business personnel rely on tools to solve many problems that used to be solved by data analysts, resulting in a decrease in job demand and an increase in the threshold of existing positions. The change in the national economic cycle and the impact of the epidemic have caused many companies to live carefully. As a "high-cost" functional department, the risk of data being cut is extremely high. The promotion ceiling was obvious, and most companies had smaller teams. The career paths of data analysts and data engineers were diverse and could meet the career planning needs of different groups of people. Data analysts could be promoted from junior analysts to senior analysts, data scientists, and even data department managers. Data scientists were the common development direction of data analysts and data engineers. This position required both professional skills. At every stage, one had to constantly learn new skills to improve their professional level. " When a programmer meets a psychologist " is equally exciting. Everyone is welcome to click to read it!

It's all about presenting the data clearly and highlighting the key points. You need to make it easy for people to understand the story the data is telling.
Mobile Data Card Pure Data Card
Pure data cards generally referred to IoT Link, which were different from regular mobile data cards. Regular mobile data cards had many functions, such as making calls, sending text messages, etc., while pure data cards only had data functions. The monthly rent of a regular mobile data card was an entire number. If the monthly rent had a decimal point (such as 9.9, 19.9, etc.), it might be an IoT Link. Regular mobile data cards can be recharged in official business halls (such as Green Weiwei, Blue Baby, Palm Business Hall, etc.). If you can only recharge through a third-party platform, it may be an irregular card. In addition, most mobile data cards had contracts, and there were few long-term plans. The data was usually general data + targeted data. The first month of data was converted by the day, and the first month of phone bill was free. The novel "Gilded Palm" is equally exciting.
