Final answer:
RAW images are not commonly used because they are highly compressed; rather, they are large uncompressed files. JPEGs are preferred for their ability to support colors and compress images effectively.
Step-by-step explanation:
The statement that RAW images are the most common and convenient image files to work with because they are highly compressed into a small size is false. RAW files are usually very large because they contain all the data captured by the camera's sensor with no compression or processing. This allows photographers greater flexibility when editing images, as no information has been discarded. On the other hand, JPEGs are the most common format for digital photos because they strike a balance between image quality and file size using compression.
JPEGs are preferred because they support millions of colors, making them suitable for colorful digital photos, and they utilize compression to create smaller image files that look good and save space. Two main reasons for using the JPEG format for digital photos are its color support and its ability to compress images effectively.
