About Multiple TIFF
Multiple TIFF image format provides for storing a stitched panorama where each original image is in its own TIFF image file. After saving a panorama in Multiple TIFF format, you use an external blending program such as Enblend or Smartblend to blend the layers into a finished panorama. The Panorama Factory includes powerful built-in blending tools, but some users may feel that external blending software produces better results under some circumstances.
When you enter a file name on the Save Image As dialog box, The Panorama Factory appends “_01.tiff”, “_02.tiff”, etc. to create the actual output file names for the individual layer files.
The PSD export filter can be applied only to stitched images and crops of stitched images. The Panorama Factory creates a TIFF image file for each original image. If you have cropped the panorama, some portions of original images may fall outside the cropping bounds. In this case, the boundaries of the image files are set to The Panorama Factory’s cropping bounds.
You can use options on Multiple TIFF settings dialog box to control whether The Panorama Factory’s own layer blending is applied before saving the TIFF files. Normally, if you are using external blending software you would disable The Panorama Factory’s blending.
Using other options on the Multiple TIFF settings dialog box you may also choose to crop the individual layers images or leave them uncropped. If you leave them uncropped, the parts that fall outside The Panorama Factory’s cropping bounds are written to the TIFF files. This means you can crop the finished image with an external program. Cropping individual layer images reduces the size of the TIFF files, but it limits your ability to edit the overall cropping in Photoshop.

Capabilities of the Multiple TIFF export filter
- Stitched and cropped images only — The Multiple TIFF export filter can be applied only to stitched images and crops of stitched images.
- Warping— Each original image is warped before saving in its own layer file.
- Alpha channel mask — The TIFF alpha channel is used to produce the blending effect used by The Panorama Factory’s stitcher. The blending effect can be disabled.
- Associated or unassociated alpha channel — The Multiple TIFF export filter provides for marking the alpha channel as either associated or unassociated with the image data. Some external blending programs require a setting for this option. Refer to the documentation of the program you are using to determine whether one or the other is required.
- 8 bits or 16 bits per color channel — The PSD export filter can save with 16 bits per color channel if the stitched image was made with 45-bit pixels. Photoshop CS or newer is required to read PSD files with 16 bits per color channel. If you have an older version of Photoshop, you should use 8 bits per color channel.
