Tiff image display wrong (tiff tags not interpreted)

[andife]

Hello, thank you for your answer.
I tried to reproduce what you were saying

Code:

user@pc1:~$ convert gimp_question3.tif gimp_question3_afterconvert.tif

user@pc1:~$ tiffinfo gimp_question3.tif 
TIFF Directory at offset 0x8 (8)
  Subfile Type: (0 = 0x0)
  Image Width: 3 Image Length: 9
  Resolution: 1200, 1200 pixels/inch
  Bits/Sample: 8
  Compression Scheme: None
  Photometric Interpretation: min-is-white
  Samples/Pixel: 1
  Rows/Strip: 9
  Planar Configuration: single image plane
  ImageDescription: ImageJ=1.52e
unit=inch

user@pc1:~$ tiffinfo gimp_question3_afterconvert.tif 
TIFF Directory at offset 0x24 (36)
  Image Width: 3 Image Length: 9
  Resolution: 1200, 1200 pixels/inch
  Bits/Sample: 8
  Compression Scheme: None
  Photometric Interpretation: min-is-black
  FillOrder: msb-to-lsb
  Orientation: row 0 top, col 0 lhs
  Samples/Pixel: 1
  Rows/Strip: 9
  Planar Configuration: single image plane
  Page Number: 0-1
  ImageDescription: ImageJ=1.52e
unit=inch

so the convert of imagemagick changes the "Photometric Interpretation".

But what does "Inverting LUT" mean? This is not a tiff-tag?
