when saving an image using tile width at 256, tile height 256 and lzw compression on the image I'm linking below, the output is a black image.

It worked for me on macOS with current homebrew:

$ vips tiffsave KatherineMcLean_FESP.tif x.tif --compression lzw --tile --tile-width 256 --tile-height 256

$ vips copy x.tif x.jpg

And x.jpg is viewable.

x.tif looks black in the Apple preview tool (though it is not black). Perhaps there is a problem in their libtiff?
