This is what I get for a panorama with crop applied in hugin. What is the important aspect? I can't see it. languitar@miles:~$ tiffinfo Desktop/temp/DSC_6577\ -\ DSC_6589.tif TIFF Directory at offset 0x8 (8) Subfile Type: (0 = 0x0) Image Width: 2969 Image Length: 2769 Resolution: 150, 150 pixels/inch Position: 29.8667, 7.63333 Bits/Sample: 16 Sample Format: unsigned integer Compression Scheme: LZW Photometric Interpretation: RGB color Extra Samples: 1<unassoc-alpha> Orientation: row 0 top, col 0 lhs Samples/Pixel: 4 Rows/Strip: 88 Planar Configuration: single image plane Make: NIKON CORPORATION Model: NIKON D7000 Software: Hugin 2013.0.0 built by Matthieu DESILE Artist: Johannes Wienke Copyright: Johannes Wienke EXIFIFDOffset: 0x688 ICC Profile: <present>, 940 bytes TIFFReadCustomDirectory: Warning, Unknown field with tag 42033 (0xa431) encountered.
