Stoves and goldThere was a story about a very poor family who lived on a raw coal stove for warmth. The protagonist found two pieces of gold while sorting out the coal ash. There was a similar story. A man found a piece of gold in a coal stove and found it in his brother's belongings two years later. If one wanted to purify the gold with impurities found in the coal stove, they could use the method of the Swiss PMP Gold factory. First, put the gold bars into the furnace, melt the gold into a liquid, and then perform the electrorefining process. Then, connect it to the power supply to become the positive pole, and then immerse the positive pole in the solution to remove the impurities. Finally, pure gold could be obtained, which could be melted into different types of products, such as gold grains, gold bars, or gold bars.

How to differentiate between a picture taken by a camera and a mobile phoneYou can distinguish whether the picture was taken by a camera or a mobile phone from the following aspects:
1. ** Picture quality and color resolution **: Cameras usually have obvious advantages in picture quality, color resolution, and tolerance. The camera was equipped with a large sensor and a high-quality lens, which could provide better image quality and a wide dynamic range. In low-light scenes, the large sensor could get more light and better dark details, while the mobile phone was limited by the size of the smaller sensor and lens, so the image quality and details were slightly inferior. If it was difficult to distinguish on the phone, you could put the picture on the computer or on the PS to check. It would be easier for professionals to distinguish.
2. ** Picture resolution and size **: Cameras are usually equipped with large-sized sensors, which can produce higher-resolution photos. They also usually support taking photos in the RAW format, saving more image information and larger file sizes. The size of the phone camera's sensor was relatively small, and the number of resolution was usually between 10 million and 40 million. Due to the size of the sensor and the quality of the lens, the size of the picture taken was usually smaller than that taken by the camera.
3. ** Depth-of-field control **: The camera's sensor size large, and the lens aperture can be adjusted. For example, if you use a high-quality lens with a large aperture or a constant large aperture, the depth of field control and out-of-focus imaging effect will be significantly different from that of a mobile phone. Although the cell phone could simulate the aperture adjustment effect through software, the difference in optical structure made the depth of field effect inferior to that of the camera.
4. ** Viewing angle and composition **: The size of the camera's sensor determines that its viewing angle is narrower than that of a mobile phone. Under the same focal length and shooting position, the camera has an advantage in shooting vast landscapes or magnificent buildings, while the mobile phone has a wider viewing angle and is suitable for shooting close-up scenes. Moreover, the phone screen was small, so the composition needed to be more detailed.
5. ** Light and texture **: The camera has a larger aperture, longer exposure time, and better control of light to obtain clearer photos. The camera's sensor, image processor, and algorithm were more powerful than those of a mobile phone. Under the same conditions, the image texture and color performance were better.

The camera continued to delay the shootingHe wasn't too sure what 'continuous camera delay photography' meant. If it's about how to use a camera for time-lapse photography, here are the relevant points:
** I. Pre-planning and preparation **
1. ** Thesis and Plan **
- He chose scenes with obvious dynamic changes such as clouds, sunrise and sunset, and city traffic as the theme. The estimated total shooting time and the estimated number of shots were used to calculate the shooting interval. For example, if you want to record changes for two hours, you need to take one photo every 15 seconds. You need to take 80 photos in total.
2. ** Equipment and accessories **
- [Cameras: Use a digital single-lens reflex camera, micro-camera, or advanced portable camera with manual mode and B-door (long exposure) function.]
- "Lenses: Choose the focal length according to the subject. Wide-angle lenses are suitable for large scenes, and telephoto lenses can compress the sense of space.
- Tripod: It must be sturdy and stable to ensure that the camera does not move during the shoot.
- Shutter release or remote control: Reduce the vibration of the camera and accurately control the shooting process.
- Timer or interval shooting function: Many cameras have this function built in, or you can connect an external smart timer.
** 2. Setting the parameters **
1. ** Shooting Mode **
- Manual mode (M): It can ensure that the exposure parameters are consistent during the shooting process. Aperture priority mode (A) is suitable for situations where the light changes greatly. It can fix the aperture value and the camera will automatically adjust the shutter speed.
2. ** Exposing parameters **
- Aperture: Usually choose a small aperture of f/8 - f/16 to obtain a larger depth of field, so that the front and back scenes are clear.
- Shutter speed: Choose according to the scene's dynamic. Daytime scenery can be set to 1/60 seconds or more. Starry sky delay may take a few seconds or even longer.
- <strong></strong>
3. ** Shooting interval settings **
- Activate the interval shooting function, find it in the camera menu, and activate it.
- Set the shooting start time to 3 - 5 seconds to eliminate the effect of camera vibration when the shutter is pressed.
- The shooting interval is calculated according to the expected final playback speed and shooting time. If you want to play 24 frames per second, the shooting interval should be a multiple of 1/24 seconds, usually ranging from 2 to 30 seconds, depending on the speed of the scene change.
** 3. Shooting Techniques **
1. ** Stable **
- Lock the tripod and hang a load to increase stability if necessary. Pay special attention in windy or uneven terrain. Use a tripod head to block the wind or install a windbreaker.
2. ** Focus and composition **
- Manual Focus: Focus on the point of interest in advance, lock the focus and turn off the autofocus to prevent the focus from drifting.
- Fine composition: Arrange the elements of the picture well, considering the movement trajectory of the dynamic subject and the relationship between the background and the background.
3. ** White Balance and Color **
- Fixed white balance: Set manual white balance or custom color temperature to maintain color stability.
- Shooting in the RAW format would allow for fine adjustment of white balance, exposure, and so on.
4. ** Storage and Power **
- Make sure that the memory card has enough capacity to store all the photos, and use a high-speed card to reduce the write delay.
- Bring backup batteries because time-lapse photography takes a long time.
** 4. Post-production **
1. ** import and sort **
- Use a video editing software (such as Adobe Premiere Pro, Final Cut Pro, etc.) to import the photos, select the "image sequence" option, and the software will automatically arrange them in time order.
2. ** Adjusting and Stabilizing **
- Color correction: Unify the color of the photo, and perform tone imaging, contrast adjustment, etc.
- If there was any slight movement during the shooting, use the software's stabilization function to correct it.
3. ** Editor and output **
- [Material editing: Remove the excess parts at the beginning and end, and add elements such as transition and music according to creativity.]
- Choose a high-quality programmer (such as H.264), set the appropriate bit rate and resolution, and export the final delayed video.
