[magick-users] unknown field with tag 50296 - what is this message ?

[Shameer Khadar]

Dear all,

I have around 10K images in tiff format. I need to level them using convert
-level option.
I used the following command to generate images using level.

convert 0180211b_ori.tif -level 10,1.0,35000 tt.tif

tt.tif is created with this warning message. Is this something important or
just a warning ?
convert: 0180211b_ori.tif: unknown field with tag 50296 (0xc478)
encountered. `TIFFReadDirectory'.
I googled abt it, but didnt get anything useful, hope the ImageMagicians can
let me know the details.
