This is my IRTC entry for this round (almost) I didn't have a lot of time so
it is quite simple. Testing my theory that if you use high enough quality
settings and plenty of focal blur even the simplest image can look good.
The final entry is still rendering only difference is I have toned down the
specular highlights on the strings as they look too fake. The image takes
about 3-4 days to render at 1600x1200 due to blur_samples being set to
500.. Even with this there is still a bit of graining on the image.

I have already spotted a mistake, funny how you miss these things until you
have spent 3 days rendering but I seem to have messed up the rotation of
the right hand side top string.. Oh well don't think I will get another
copy rendered before the deadline so it will have to stay like it.

Rendered with megapov using my Museum HDRI probe and one area light.

    Wow! That's an impressive image!

    My only concern is that I've never seen gold coloured guitar strings 
before, and actually, your guitar looks like an acoustic which would have 
cat-gut strings for the top three, (steel sprung for the lower three).

     (This is only my experience, you may know different).

   I can't see this?

    Turn everything fancy off for rendering, and you would still have a fine 
image for the IRTC.

     Excellent wood grain.

       Good luck,

Very nice, I love the texturing.  Great brushed metal on the tuning keys.

That's why I rarely get quality renders out.  Halfway through a 24hour 
render I stop it to change something.

Nice!  Very convincing on the wound strings, the highlights on the plain
ones look a little soft though.  If you're using phong I'd say a higher
phong_size.

This topic is one I'd really like to participate in, but I've been home only
about a week total in the last two months, so doubt I'll get something done
in time. I've got a couple ideas started, but neither looks like it'll
develop to a point I'd submit it by the deadline :-(

Why, oh why couldn't this topic have waited til next round!

I used to have only steel strings on my acoustic guitar and the lower 
strings looked a bit like gold. The sound was more clearly. I liked it 
more than the soft sound of the platic (cat-gut?) strings. But it was 
harder for my fingertips. ;-)

Of course this are my two eurocents,

I always put steel plain strings and bronze wound strings (they look golden
and some alloys actually contain a small amount of gold) on  my guitars. one
puts gut strings only on classical guitars.

Well done !
You'd better clean up your guitar before shooting it ;-)
I miss a pretty golden "Martin&Co. EST.1833" kind of logo
For the rotation of the string, do you mean it doesn't fit with the machine
head rotation?

Hi Steve,

Thanks.

Well spotted for noticing it is meant to be an acoustic guitar, you have
already proven that you know more than me about guitars. I only know it is
acoustic because the photo I used to model it from said so.. The photo did
however have steel/gold looking strings.

Not that I like to elaborate on my mistakes but I rotated the string around
with out rotating the tuner so the part of the string that goes through the
hole actually goes through the tuner.

Thanks, I was fairly pleased with this texture as well, source is below..

Hi Trevor,

Thanks, I actually decided against using normals for the brushed metal
effect as I thought it might not work well enough when viewed close up. I
actually used a difference (a bit OTT but it does look better).

I think only my RSOCP images have no errors, normally though after spending
a couple of days rendering I cannot be bothered to stop/start again as I am
usually keen to use my computer for something else. I figure if it took me
that long to notice the problem then most people won't even spot them.

Thanks, I spent a fair amount of time trying to get the highlights looking
correct but couldn't seem to get them just right. I might try a couple of
adjustments and see if I can get it done before the deadline.
