JPEG vs RAW

Part 1
                3 Advantages of a RAW

•  The 8-bit jpeg format can contain a maximum of 16 million colors (256 shades each of red, green, and blue). Not bad, I suppose. 
• Raw files record and retain all the information captured by the sensor; this takes maximum advantage of any given camera’s dynamic range capabilities — the ability to accurately record the subtle transitions between the lightest and darkest parts of a scene. This translates into properly exposed highlights and shadows that don’t lose detail.
• Since raw files are lossless/uncompressed files, they don’t exhibit any of the jpeg-related compression artifacts that can really distract from the aesthetic quality of an image.

1Disadvantage of a RAW

• Although shooting in RAW gives us more flexibility to make adjustments, this will make for a slightly longer workflow. As mentioned before, RAW images need to be processed and then converted to JPEG for HDR processing.

3 Advantages of a Jpeg

• Since the images are already processed and are ready to be directly taken into your HDR processing software, shooting JPEG bracketed images is generally a slightly easier workflow. '
• JPEG images are much smaller than RAW images and therefore consume a lot less storage and need much less processing power.
• Smaller size also means faster and more efficient backups.
• 1 Disadvantage of a JPEG

it is impossible to shoot a single-shot HDR image. This is because a JPEG does not capture enough tonal range or does not have the information to give us the options to process the image the way we want to in Lightroom.
