Electronic digital storage format, why should digital cameras format memory cards?

1. The main reason why the new memory card should be formatted is because after the camera itself is formatted, some system information of the camera is stored in the card, and it can be used without formatting. Basically, it's not too much of a problem, but it's best to format it.

2. The memory card is damaged, resulting in the loss of the format and the camera does not recognize it.

3. Virus in the memory card, resulting in format loss, camera is not human.

4. The memory card is formatted in NTFS format on the computer, and the camera does not recognize it. If this happens, it means that the state of the card is unstable. It is recommended not to use it to prevent data loss from corruption. Use Disk Utility to measure the status before using it.

In that case, there may be a virus Trojan in it. Format it to avoid these problems!

If the digital camera prompts you to format the memory card, it means that the camera does not recognize the memory card.

If you don't format it, you won't be able to shoot with this card.

The main reasons for this problem are as follows:

1. The memory card is damaged, resulting in the loss of the format and the camera does not recognize it.

2. Virus in the memory card, resulting in format loss, camera is not human.

3. The memory card is formatted in NTFS format on the computer, and the camera does not recognize it.

If this happens, it means that the state of the card is unstable.

This card will not be used for the first time to prevent damage and loss of data.

Use Disk Utility to measure the status before using it.

Most of the reasons why the digital camera card prompt is not formatted are due to hot unplugging, such as: the camera is not turned off to pick up the card, inserted into the computer and not safely exited to pick up the card, etc., so that the digital camera card prompt is not formatted due to unplugging.

2. Running the software, we choose "Universal Recovery" to help us retrieve the lost files in the computer hard disk effectively and comprehensively.

3. After clicking to select "Universal Recovery", we will enter the disk partition interface, we select the hard disk partition that needs to be recovered, click the "Start Scan" button, the software will scan the disk we selected, we need to wait patiently.

4. After the scan is completed, we can see the scan results on the most side of the software interface, we click on the files in the scan results, find the lost files, on the right side we can preview the data in the files, and then click the "Recover" button.

5. Then a page will pop up, set the path to save the recovered files, and we can click the "OK" button to recover the lost files in the computer hard drive.

In general, JPEG is fine, and the format is different because different industries have different requirements for drawing. Nowadays many cameras use RWA files, which are used for post-PS processing.

1. There are three categories of digital camera formats, the first is JPG (JPGE) format, which is available in all cameras and camera phones; The second category is RAW format, which is available for high-end camera phones, mid-to-high-end portable phones, mirrorless, single-handed, single-lens reflex, and double-reflex; The third type is the TIFF format, which is only available for high-end SLR and double reflex systems;

2. JPG format. JPG stores a single bitmap in 24-bit color, depending on the level of the camera, JPG can also be subdivided into different compression ratios, such as ultra-fine JPG, fine JPG, standard JPG, etc., some also use L, M, S, etc. to represent the compression ratio of JPG, the larger the volume of JPG, the more image information it contains, the richer the imaging details, but the larger the storage space it occupies (the same goes for RAW). JPG is a universal format, the advantage is that the application range is the widest, all image carriers can read JPG documents, the disadvantage is that the JPG format generated by the camera is affected by the intelligence of the camera image processor, and the re-creation space is relatively small;

3. RAW format (some cameras use DNG format, such as Leica, etc., which is the same as RAW format, but it is more versatile). The original meaning of raw is:"Unprocessed"According to the different levels of the camera, RAW can also be subdivided into large volume (L) RAW and small volume (S) is a compressed original image data package, divided into lossy compression and lossless compression, more than 14bit (including 14bit) RAW is called lossless compression, and less than 12bit (including 12bit) is called lossy compression. The advantage of RAW is that it has the most abundant image data, which can be recreated (that is, post-production, jpg can also be post-processed, but the post-production margin is much smaller than that of RAW), and the authorship of the photographer can also be proved, and the disadvantage is that special image software is required to read, and it must be converted to jpg format to be used as a general ** format;

4. TIFF format. TIFF is an uncompressed (uncompressed) raw image packet that is only available in high-end cameras, and is equivalent to lossless compressed RAW. The disadvantage is that the image capacity is large, and the advantage is that it does not require special image software, and it belongs to the professional universal ** format, which is the most widely used image format for professional images (such as printing, etc.).

Image files scanned in black-and-white binary mode are generally stored in TIFF (G4) format. Documents scanned in grayscale mode and color mode are generally stored in JPEG format. The selection of compression ratio during storage should be based on the premise of ensuring that the scanned image is clear and readable, and the storage capacity should be reduced as much as possible.

Scanned images for web queries are provided and can also be stored in CEB, PDF, or other formats.

Hello! **Files in JPEG format are minimal as this is a compression format.

If it's any of the three you listed, then it's TIF

However, it is recommended to use either gif or jpeg.

Because not only is the compression large, but the picture quality is also better.

JPEG format is the smallest, but it also has to take into account the image quality.
