Thanks, 
have you tested it with JPEG compressed TIFFs? I remember there were some problems before with those.

I test with this image. It works fine.

Can I get another JPEG compressed tiff image?

Try these two please: one is from TIFF test suite, another one is saved by Imaging with older LibTiff version.

I tested samples. It works fine  :)

I heard tiff jpeg compression problem is fixed at 3.9.2.

Hello! I was very happy to find your forum that helped me to resolve my problem with reading exif in TIFF files. So I think it may be useful for you or for somebody:
 I've a little bit modified LibTiffDelphi.pas (3.9.1) found here so  it's possible to read exif tags in TIFF files using LibTiff 3.9.4 in such way:

TIFFGetField(pTiffFile,TIFFTAG_EXIFIFD,@ExifIFD)
TIFFReadEXIFDirectory(pTiffFile,ExifIFD)
TIFFGetField(pTiffFile,EXIF_TAG_NAME,VARIABLE)

Thank you for all! :)
