   Your rafters and plywood are so attractive you don't want a finished ceiling under them?  

   My recent roof was similar but I won't use asphalt shingles, if that was your plan.  I installed a copper roof on full dimension 5/4 purlins with 1 1/4" copper nails.  Looking up, the nails don't show but one can see the diagonal braces I let into the oak rafters.  Mine's a tractor shed, but I too care what it looks like.

   You could bump the plywood up to 3/4" and use 1" nails.

   Use translucent fiberglass panels instead.

   I've dealt with this situation several times by installing 5/8 in. T1-11 over the rafters with the finished face down. Then, I installed 1/2 in. OSB over the T1-11. Use 1 1/4 in. nails for the roofing. Done.

   Put something you want to look at on those rafters.

   Fur up each rafter with 1/2-3/4" strips.

   Put down your sheeting and shingle away.

   Examples of good looking-1x8 barnsiding (v-groove) stained.  The heat will cause the knots to halo-or blead through-not entirely a bogus look.............if you stain with a light, solid color stain.

   Other T&G boards.

   Decent exterior grade paneling if you can find it.

   T-111, but be wary-the rough sawn look is a cobweb magnet.

   We run into this situation alot.  Sometimes with roofs and other times with outbuilding sidewalls.  If we are shingling a roof or sidewall with cedar shingles and the homeowner doesn't want nails to show on the underside/inside we use 2"x6" tongue and groove spruce for the sheathing.  I have never thought of the T-111 idea though.  That could look nice and give you some shear strength too, whick is always a good thing.

   Fine

   Forgot another sheetgood, Arauco beadboard.

   the Long edges of this and t-111 are invisible and the butts are  hidden by the rafters.

   shed roof

   Im dealing with this right now in a really windy area in hawaii and dont want to skimp on the nail size, so what i came up with was to use two layers of 90# felt under my shingles which will give you about a 1/4 inch and your shingles are 1/4 to 5/16 thick.To ad strength i used a bead of roof tar on every row of shingles and a 3/4 deck screw on the corners of each shingle along with 1" roof nails.it slows down the shingle process a bit but visually it works.
