    Photoshop vs. WinZIP

    Can anyone explain why Photoshop compress .TIF file in ZIP better than any archiver?


    Example:


    Original .TIF file size: 39.2
    Compressed by WinZIP: 29.5
    Compressed by Photoshop: 18.1

    photoshop is using zlib in latest specs away from LZW but sometimes lzw+prediction can beat zlib and also there is something called "layer compression" .. did you test Stuffit it blindly beat winzip and has photoshop plugin that CG's are using to share designs.
