The ISH file type is associated with the Image System (Hires), a format used for storing high-resolution images. Originally designed to handle detailed graphical data, ISH files are typically utilized in environments where image clarity and precision are paramount. These files can encompass a wide range of visual data, from digital art to sophisticated scientific imagery. Due to their high-resolution nature, ISH files are often larger in size compared to standard image formats, necessitating more storage space.
An image file format mainly used in storing cell phone photos and they are saved in the High Efficiency Image Format (HEIF). They store one or more images and the metadata description for each image. Also known as .heif files
