Does photography have to be in RAW format? Why do some people say that JPG format is not photography? What is the difference?

We often see photographers' friends posting their latest photography works on social software such as friends circle, which obviously shows that their published works are better. Those photos are accurate in exposure, bright in color and perfect in saturation, so do they make thorough preparations before pressing the shutter every time? Not necessarily!

Then we have to say that there may be some things that can't be considered at the moment of pressing the shutter, such as underexposure or overexposure, and the camera settings are not adjusted back to make the photo saturation too rich or too lacking. These can be retouched later! Then it became what we saw as "beautiful camera work!"

I have to talk about RAW format and JPG format here!

First, let's look at the imaging principle of the camera. First, when we enter the camera, the optical signal is converted into an electrical signal, and then the electrical signal is converted into a digital signal, and the digital signal is superimposed into unprocessed raw data. At this time, an original file is formed. Because the picture has not been processed, it looks gray.

If you choose JPG format, the unprocessed raw data will process your picture according to various camera settings, and discard irrelevant data for compression, and finally form a JPG format picture. Because of the optimization and processing of the camera, the picture looks gorgeous.

For professional photographers, they like unprocessed RAW files and use post-processing software such as LR and PS to modify their works. The benefits are obvious. They can discard irrelevant image information through their own ideas, keep what they like, and even brighten curves and save pictures with serious underexposure, with almost no loss of image quality, because the RAW file retains all the details!

But for JPG, the camera has already processed the picture through your settings and discarded irrelevant data, so there is little room for post-processing because the part you want to process may have been discarded by the camera.

In this way, some people will say that JPG format is not photography, because the early and late stages of photography are inseparable, and the advantages of RAW format are undoubtedly stronger than JPG. Even some professional cameras no longer have the option of direct JPG format!

I wish you happy every day and can take excellent photos. The picture comes from the internet.
