Bitmap Image File
The classic uncompressed Windows image format.
BMP (Bitmap) is a raster graphics image file format used to store bitmap digital images, independently of the display device. It is one of the oldest image formats still in use, historically associated with the Microsoft Windows operating system.
BMP files typically store color data for each pixel in the image without any compression. This results in very large file sizes but perfect quality and extremely fast decoding. While it supports RLE compression, it is rarely used.
Introduced with Windows 3.0 in 1990. It was the standard format for Windows wallpapers and system graphics for decades.
Photoshop Big
The 'Large Document Format' for managing gigapixel images.
PSB (Photoshop Big) is an extension of the PSD format designed to break the barriers of the 2GB file size limit and 30,000 pixel dimension limit of standard PSD files. It is structurally almost identical to PSD but uses 64-bit offsets inside the file to support massive files up to 4 Exabytes (theoretically) and 300,000 pixels in width/height.
Internally, a PSB file mirrors the block structure of a PSD (Header, Color Mode, Image Resources, Layer and Mask Info, Image Data). The key difference is the bit-width of length integers; PSB uses 8 bytes (64-bit) where PSD uses 4 bytes (32-bit) for describing file offsets and dimensions.
Introduced in Adobe Photoshop CS (v8.0) in 2003 to support the growing needs of astronomical imaging, billboard printing, and HDR photography.
