Question on install 8bits vs 16bits to support 16bits

[feelart]

RE: http://www.imagemagick.org/script/download.php

The Windows version of ImageMagick is self-installing. Simply click on the appropriate version below and it will launch itself and ask you a few installation questions. Versions with Q8 in the name are 8 bits-per-pixel component (e.g. 8-bit red, 8-bit green, etc.), whereas, Q16 in the filename are 16 bits-per-pixel component. A Q16 version permits you to read or write 16-bit images without losing precision but requires twice as much resources as the Q8 version.

Compatibility
Maybe it's obvious to you, but for me it is ambiguous, does this means:
Q8 version permits to read 16-bit images, converts it in 8-bit and only exports in 8-bit
or
Q8 version can NOT read 16-bit images, only reads 8-bit image and solely exports in 8-bit.


Thanks for answering and possibly updating the info on http://www.imagemagick.org/script/download.php

It means the first, "Q8 version permits to read 16-bit images, converts it in 8-bit and only exports in 8-bit"
