.TIFF & .BMP files
A Panorama Factory project is actually a collection of files.
When you choose 45-bit image files, image data are stored in individual files with .tiff extensions (double f). These are TIFF (Tagged Image File Format) files with 48 bits per pixel - 16 bits per color. Only the most significant 15 of the 16 bits are used to store image information. The least significant bit is used for housekeeping information such as noting which areas of a warped image do not correspond to areas of its original, unwarped image.
When you choose 24-bit image files, image data are stored in individual files with .bmp extensions. These are Windows device independent bitmap files with 32 bits per pixel - 8 bits per color. Only 24 bits of each 32 are used to store image information. The additional 8 bits are used for housekeeping information such as noting which areas of a warped image do not correspond to areas of its original, unwarped image.
Color data stored in .tiff files remain unaffected by color correction values. That is, the color correction values affect only the display of the .tiff files. To commit the color correction values you must save an image file with a .tif (single f), .bmp or .jpg extension using the File Save View As command. Usually, .tiff files are unsuitable for printing or importing into other applications.
Color data stored in .bmp files are affected by color correction values (if you enable color correction) and so are suitable for printing or importing into other applications.
