File Formats

Three advantages of a RAW file: Lossless data, more control in editing the photo post shot, and an uncompressed file.
One disadvantage of a RAW file: produces a very large file, so if you don't have a memory card that holds a lot of space you will be limited in how many pictures you can take
Three advantages of a JPEG file: sharper and higher in contrast, immediately suitable for printing and sharing, not (usually) in need of correction.
One disadvantage of a JPEG file: some color and resolution are lost when processed by camera.

1. A RAW file captures and retains all the data from a photo without compressing it
2. White balance, contrast, highlights, shadows, colors, and saturation
3. Some cameras cannot shoot in RAW, and RAW files take up a lot of space
4. Most professional photographers edit and enhance their photos

1. I have used JPEG
2. A raster image is made up of pixels, while a vector image is made up of paths. Raster images don't retain their appearance as size increases, while vector images do.
