Hi Harsha,

No complete answer on your question but on this site a number of private tags are mentioned. It would be great if you would add information about your private tags too. http://www.awaresystems.be/imaging/tiff/tifftags/private.html

Private tags are difficult to handle as they can mean anything. If you do not know their meaning the savest strategy is not copying them at all. If you know the meaning of the tag (eg from site above) you can deduce if your modifications will 'corrupt' the private tag or not.

sofar my 2 cents,
regards,
rob tillaart
