Without compression, each photo would take up a significant amount of storage space, limiting the number of pictures that can be stored on a 4GB SD card.
Common image formats and their storage sizes
Different image formats have varying storage requirements. JPEG (Joint Photographic Experts Group) is the most common format used for storing photos because of its ability to compress images without sacrificing quality. A high-quality JPEG image can occupy about 3-5MB of storage space, while a medium-quality JPEG may range from 1-2MB. On the other hand, RAW files, which preserve all the original data captured by the camera’s sensor, can take up several times more space compared to JPEG files.
Other formats such as PNG (Portable Network Graphics) and TIFF (Tagged Image File Format) offer lossless compression, meaning they retain all the original image details but result in larger file sizes. PNG images typically have a larger file size than JPEG, making them less practical for storing numerous photos on a limited-capacity SD card. TIFF files, while maintaining excellent quality, can easily exceed 10MB per image.
It’s important to note that the storage size of an image is impacted not only by the format, but also by the content of the photo. Highly detailed or complex images tend to have larger file sizes compared to simpler or less-detailed images.
By understanding the different image formats and their storage sizes, photographers can make informed decisions about the compression and format settings on their cameras. Opting for JPEG compression and adjusting the quality settings can help strike a balance between image quality and storage capacity.
