signature: TIFFField(TIFFTag tag, int value)

according to docs,

     * Constructs a {@code TIFFField} with a single non-negative integral
     * value.
     * The field will have type
     * {@link TIFFTag#TIFF_SHORT TIFF_SHORT} if
     * {@code val < 65536} and type
     * {@link TIFFTag#TIFF_LONG TIFF_LONG} otherwise.

TIFF_LONG is "32-bit (4-byte) unsigned integer" (http://partners.adobe.com/public/developer/en/tiff/TIFF6.pdf), so, e.g., 2^32 -1 is a correct value.

but we obviously cannot set values greater than Integer.MAX_VALUE (2^31 - 1) using this constructor (NOK) (exception - negative argument).

possible solution -- to use long type for the 2nd arg.
