I got the link from Joris and studied about it. As Phil said that EXIF IFD contains InteropIFD ( TIFFTAG_INTEROPERABILITYIFD), but i got that this is part of normal image IFD. Libtiff just read the TIFFTAG_EXIFIFD tag but doen't parse the EXIFIFD. Anyone could suggest me that how it will be handle by libtiff. Or i have to handle it independently without using libtiff. Act our main aim is to make exact copy of the image, so at this point of time i don't want to ignore any tag or IFD. Thanks Anurag
