Well, RAW is basically the unprocessed data from the camera's sensor. It contains a lot more information compared to JPEG. JPEG, on the other hand, is a compressed and processed format. A major difference is in the editing capabilities. With RAW, you can make much more significant adjustments to things like white balance, exposure, and color grading without losing quality. JPEG, once you start making major edits, can quickly degrade in quality because it has already been processed and compressed by the camera.
The 'akaza sad story' might refer to the tragic backstory of Akaza from Demon Slayer. Akaza was once a human with a strong will. He had a family and a normal life, but due to various misfortunes and being turned into a demon against his will, he lost his humanity and was forced to do cruel things. He also had a lot of inner struggles as he still retained some of his human emotions deep down, which made his story a sad one.
For professional photography, RAW is generally better. It offers the most flexibility in post - processing. Professionals often need to make precise adjustments to images, and RAW allows for that. For example, in a studio setting where lighting conditions need to be perfected in post, RAW gives the ability to change white balance and exposure in a more accurate and non - destructive way compared to JPEG.
