Appreciate the comments on the photos... yes, being in love with your subject matter helps :wink:
Setup in the basement is anything but glamorous...
Base under the paper is a 32 x 48 x 3/4 piece of MDF sitting on four 5-gallon buckets.
There's currently 42" wide paper hung on 3 sides minimum, sometimes two additional vertical sections at 45° angles
with a gap for the camera to poke through, illuminated by standard 24 x 48 4-bulb diffused fluorescent fixture in a dropped ceiling.
Sometimes white or black card held in a boom tripod, also generally at an angle to the guitar.
Cropping followed by levels adjustments in photoshop to get a clean background, but not much else.
Guitar is positioned so that the stand is concealed.
Camera is a Canon T5i on a tripod in manual mode, no flash, various bracketing going on but
generally slow shutter speeds.
The D25 in the second photo (Corona-built, fantastic instrument!) was shot without using the additional 45° angled paper
or card in the boom tripod, hence the darkness on the left side of the top of the guitar - which can be ok,
depending on what I'm trying to show.
