Adobe After Effects®Register TIFF tag and compression numbers
You may register up to four TIFF tags or compression numbers at one time. It is recommended that you register only as many as you need immediately. You can always return and register additional tags. If you have special requirements, use the Feedback Form. Select the TIFF Tag/Compression Number Registration option.
Read the section entitled "Private Fields and Values" on page 8 of the TIFF 6.0 Specification before registering.
