Tried a few more shots the other night, but unfortunately the temperature was causing moisture to build up on some of the panels, so I only got a few photos. Tried some layering techniques, used a different light source (worked better in some ways, but was also challenging to get the right amount of light.
Composition will have to wait for a better opportunity. Thanks again for the tips so far. One day I'll figure out how this camera works.
