Every photo taken by the camera has an attachment. I don't know what happened. Who can solve it?

You may have set the photo file to the storage mode of RAW+JPG! In this way, every time you take a picture, the camera will automatically store the RAW mode photos and JPG photos. You can look at JPG photos, and the original photos need to be processed by special software! What is the RAW format?

Nowadays, many digital cameras can store not only JPEG and TIFF images, but also RAW images. In fact, RAW is not an image format, but an original record of the level when the CCD or CMOS of the camera converts the optical signal into an electrical signal. It is obtained by simply digitizing the image data without any processing inside the digital camera, that is, the electrical signal directly obtained by CCD and other photographic components. For example, for a 3-megapixel digital camera, a RAW file stores 3 million photosensitive data points. When we usually shoot JPEG format, the digital camera adds parameters such as white balance and saturation inside the digital camera on the basis of RAW format, and then generates image data and compresses it.

RAW data processing software attached to digital cameras can convert RAW data into common image data such as TIFF, and users can set parameters such as white balance, sharpness and contrast at will, so that users can create their favorite images. Processing RAW format image data is different from JPEG image because image data will not suffer from image quality deterioration.

How to get RAW format files? You must have a camera that supports RAW format to create RAW format files. You need to save the camera in RAW format before shooting.

You can use Photoshop or Bridge to process RAW format files.

In Photoshop, you can open RAW files directly. In Bridge, browse to the RAW file to be processed, select one or more RAW files, right-click them, and then select Open in Camera Raw (you can also use the menu File → Open in Camera Raw).
