What is the file format of files with the RAW suffix? What software can be used to open files in this format?

Raw is a raw image file format, generally used by digital cameras and other equipment. Some professional image designers also often use this image file.

Generally, you can use xnview and acdsee. Editing can use photoshop, etc.

Advantages of JPG format

·The file is relatively small, and this format can accommodate more in the memory card Photos

·The image quality meets most applications, such as family photography, photojournalism, etc.

·Small files are easy to transfer and publish online. This is more important for photojournalists.

·Many players do not have the time or inclination to do post-processing.

·When most digital cameras record pictures in RAW format, they cannot complete the picture very quickly, and some momentary shots are difficult to capture. Low-end cameras cannot record RAW format at all.

Advantages of RAW format

·RAW files are almost information obtained directly from CCD or CMOS without processing. Through post-processing, photographers can maximize their Artistic talent.

·RAW files do not have white balance settings, but the real data has not been changed, which means that the author can adjust the color temperature and white balance arbitrarily without any loss of image quality.

·Color linearization and filter row transformation are processed more quickly on computers with microprocessors, which allows the application of more complex algorithms that are not allowed on cameras.

·Although RAW files are accompanied by saturation, contrast and other mark information, their actual image data has not changed. Users can freely make personalized adjustments to a picture without having to base it on one or two preset modes.

·Perhaps the biggest advantage of RAW is that it can be converted into 16-bit images. That means there are 65,536 levels that can be adjusted, which is a big advantage for JPG files. This is very important when editing an image, especially if you need to make important adjustments to the shadows or highlights.

JPG or RAW?

In fact, we can think that all digital cameras use RAW mode, but when we choose JPG as the storage format, we submit the image to the RAW conversion program built into the camera. If we allow RAW as a storage format, it means that photos can be better adjusted on a complex platform, and even if the modification is not good, it can be re-adjusted in the future. In other words, the choice between the two is: do you decide to do the RAW conversion in the camera now, or do it on the computer later?

Some important aspects must be decided before generating a JPG file, namely white balance, contrast, saturation, etc. The advantage of RAW is that these do not need to be carefully considered at the time, and there is sufficient time to think about it.

For some photographers (sports, news), ease of use and speed are the best, but for others this may not be the case. Of course, if you want the best image quality, RAW is the best choice. Some cameras save both JPG and RAW formats, which is great for photographers, but it also takes up additional storage space.

Some people don't like the RAW format because the files in this format are too large and they need more space. RAW files do require larger capacity and cheaper memory, as well as excellent decoding and editing software. With the continuous advancement of technology, I believe RAW will have a bright future.
