Eu só uso RAW, ha muitos anos, e não tem nenhum problema com isso. JPG limita, fotos com a quantidade muito grande de stops (EVs), fora as correções que os colegas já citaram aqui, é impossível editar satisfatoriamente em JPG.
Não sei porque ninguém ainda comentou que um JPG é um arquivo de 8 bits, o RAW são arquivos de 12, 14 ou 16 bits, é uma diferença muito grande na qualidade das informações.
Extraído do site Nikon:
https://www.nikonimgsupport.com/na/NSG_article?articleNo=000026447&configured=1&lang=en_SG"The camera either captures 12 bits of data per colour or 14 bits of data per colour depending upon the camera's analogue to digital circuitry. The table below illustrates the number of shades per colour depending on the bit depth:
8 bits ---------- 256 shades of red, blue and green
12 bits --------- 4096 shades of red, blue and green
16 bits --------- 65536 shades of red, blue and green
RAW files are 16-bit files whereas JPEGs are 8-bit files, so a RAW file can contain as many as 65536 levels of each colour whereas a JPEG file can contain only 256 shades of each colour. When an image is saved as a RAW file, the digital camera actually captures 12-bits of colour and steps it up to 16-bits. When saved as a JPEG, the image is stepped down to 8-bits."
"Benefits of shooting in RAW
The histogram of an 8-bit JPEG images will begin to band after applying small amounts of levels and the image will most likely get posterised as an effect. A RAW image preserves the continuous flow of colour tones."
