Bonneville, what's your lighting set-up and camera?
A pretty old Canon EOS Rebel T5i, just recently added an older Ultrasonic 28-135mm lens and
some external lighting. I use side curtains on this setup sometimes, and various
large pieces of brown cardboard and white board to deflect / reflect / direct / or otherwise attempt to control
light and shadow and reflections...
I'm an enthusiastic stumbling amateur, still taking way too many shots to get a few decent photos and never close
to satisfied with any of it
... but endlessly fascinated / frustrated with how light reacts / reflects on and
around the beautifully complex surfaces of a guitar, so I'll keep banging.
I'll add another thing - I see incredibly gorgeous photos of guitars all the time on instagram,
and I stop and study and marvel at how rich, interesting and soulful many of these photos are.
I don't have the knack for serendipitous still-life / kind of mind blowing shots like that, so I'm more or less
trying to stick with more of a documentation-approach to whatever guitar it is I'm photographing.
It's not the least bit sexy but I hope it captures something compelling and factual about the guitar.
