Thanks, it sounds like a patch is in the works.
I should have mentioned that those unknown tag warnings are expected
because the tiff is actually a GeoTIFF as exported from GDAL. It's an
indexed file because each pixel is actually a landscape
classification (forest, water, etc.). From a GIS standpoint it
wouldn't make as much sense as an RGB.
Thanks,
Seth

Can anyone verify? Thoughts?

I have: Version: ImageMagick 6.3.3 04/15/07 Q16 http://
www.imagemagick.org
Running convert on the TIFF to PNG produces a black image.
However, it also produces the following errors:
convert: N048W093.sm.tif: unknown field with tag 33550 (0x830e)
encountered. `TIFFReadDirectory'.
convert: N048W093.sm.tif: unknown field with tag 33922 (0x8482)
encountered. `TIFFReadDirectory'.
convert: N048W093.sm.tif: unknown field with tag 34735 (0x87af)
encountered. `TIFFReadDirectory'.
convert: N048W093.sm.tif: unknown field with tag 34737 (0x87b1)
encountered. `TIFFReadDirectory'.
Now, I noticed your original TIFF is not in RGB color space, but
Indexed. I re-saved it out as an RGB file (Photoshop) and then re-
ran the convert command. This time I got no errors and the PNG
file wasn't black...it was what I would expect it to be, the actual
image.
Just in case the IM team needs more info...
