I don''t know if I''m just obviously missing this, but I can''t find a way to convert a 24 bit/32 bit graphic in Photoshop down to 16 bit. It is rather necessary, and I can''t find a way to do it. The standard RGB with 8 bits per channel works on 24 bit level. And I can''t find anything lower than that other than 8 bit (256 colors).
So is there an easy way to do it? Maybe some button I somehow missed?
