Graphic selection of JPEG and raw

One, JPEG is a compressed photo

The basic difference is that the RAW file will fully retain the image of each pixel message and information, but JPEG is a camera based on a compromise compression, so the size of the two files are significantly different, RAW files can be JPEG file 两、三倍, it is not difficult to imagine, RAW file image quality and level sense , which is much higher than the JPEG that is straight out.

Second, RAW files need to be processed

Unlike JPEG, when a RAW file is taken, we usually use the software to process it, and then it becomes JPEG. But the biggest advantage is that we can deal with white balance, contrast, saturation and so on, but will not let the camera limited processing power, cut off the original rich information and the image level.

And a lot of cameras that can make raw files come with software that can handle raw files, but they can't expect too much, perhaps Lightroom and Photoshop will be more of a professional tool.

Third, other tips

First, many of the older small DCs are not able to take the raw format, and secondly, because the raw file is 10MB or above, pay attention to whether the memory card is enough; third, it's simple common sense that you can turn RAW to JPEG, but you can't reverse it because JPEG is a compressed format.

Four, how to choose?

If you're already satisfied with your work, it's easy to get a JPEG right. But if you want the quality of your photos to be higher, and more importantly, you want to have more flexibility in your work, you will not be able to modify it as much as JPEG, as the quality of the product is drastically reduced, RAW will be a choice. In fact, many professional photographers spend a lot of time working on photos, even more than filming, to get an excellent level of image and compete in the industry.

V. Please practice yourself.

It's no use saying so much, because you have to try it yourself, you can experience the RAW file flexibility and charm, which is very valuable. Of course, although shooting RAW can retain a rich picture of the message, but these are only the improvement in quality, can not take good photos, but also to see a lot of factors, not too dependent AH. n-us; RAW can retain a rich picture of the message, but these are only quality improvement, can not take good photos, but also to see a lot of factors, not too dependent AH.
