What is the default format used by almost all digital cameras?

• A. BMP
• B. PNG
• C. JPG
• D. TIFF

Answer: (C)

The default format used by almost all digital cameras is JPG, also known as JPEG (Joint Photographic Experts Group). This format is widely chosen for several reasons. JPG files utilize lossy compression, which significantly reduces the file size while retaining a reasonable level of image quality. This is particularly beneficial for photography, as it allows users to store more images on their memory cards and facilitates easier sharing and uploading online, where bandwidth may be limited. In everyday photography, where lighting conditions and content can vary greatly, the JPG format balances image quality and manageable file sizes, making it the preferred choice for most users. Additionally, this format provides good compatibility with most photo editing software and online platforms, ensuring that images can be easily accessed and shared. While BMP and PNG are also image formats, they tend not to be as common for photographs taken with digital cameras due to their larger file sizes and lack of support for certain color profiles or compression methods. TIFF, on the other hand, is favored for professional photography and archiving due to its lossless nature, but it generates much larger files which can be impractical for everyday use. Thus, JPG's blend of efficiency, accessibility, and quality makes it the standard format for digital cameras.
