1. Press the menu key to enter the camera setting menu, and then enter the image quality option.
2. Press the menu key to enter the menu and select the image quality option.
Select the picture format through the camera dial. In the picture quality option, we can choose raw and JEPG respectively, and the bar indicates that there is no choice. When choosing the format, we can choose different combinations according to our own needs, which is very convenient.
Gap between camera parameters RAW and JEPG:
1, the file size is different.
Both are image files. What's the difference between raw and JEPG? First of all, in terms of file size, the file in RAW format is obviously much larger than the file in JEPG format, and the volume difference between them is almost four times.
The reason why the number of files is so different is that the original format records the original information of the photosensitive element without losing any information, while the JEPG format is a compressed image file, which compresses the image file in a large proportion. Although the visual loss of JEPG is almost imperceptible, the greater the compression ratio, the higher the merging degree and the greater the color loss. Therefore, JPEG compression is a lossy compression.
2. Difference of image quality
Because the file size of RAW format is much larger than that of JEPE format, the image quality will be improved at the expense of memory card capacity. Let's compare the two groups to see their differences in image quality.
From the above comparison, we can clearly see that the image in the original format is more stereoscopic than the image in JEPG format, which improves the clarity and fineness of the image and enriches the details of the image.
Because the original format records all the information received by the sensor, its image quality will be better than the "lossy compression" JEPG format file.
