The most common format for photographic images is which of the following?

• A. TIFF
• B. JPEG
• C. RAW
• D. PNG

Answer: (B)

JPEG is the most common format because it offers a practical balance between image quality and file size, along with universal support across cameras, editors, and devices. It uses lossy compression that dramatically reduces file size without noticeable quality loss at typical viewing sizes, which makes it ideal for sharing online and storing large photo libraries. Other formats serve specialized needs: TIFF is often used for high-quality archival work and professional editing due to its large, often uncompressed files; RAW contains unprocessed sensor data and is great for heavy editing but isn’t a universal final output and requires processing; PNG is lossless and excellent for graphics or images needing transparency, but its larger file sizes for natural photographs make it less convenient for everyday photography.
