The Power of Light and Dark

I thought I would try something different. This is a glass solar radiometer sitting on a black & white check table cloth. It is illuminated from behind with a single light which is sited centrally, just out of of shot, above the black background and pointing straight at the camera.

I found that having the light in front of the camera but behind the radiometer removed any unwelcome reflections of the light itself and also believe that this makes this image a form of contre-jour.

I tried a whole range of depth of field from F2.8 to F32 but decided that the best results were with the check pattern reasonably sharp along the entire sight-line so settled on F25.

Shot in my dining room using a tripod mounted Pentax K-1 and a D FA 50mm Macro.
1sec, F25, ISO100 and -2.0 exposure compensation.

Shot raw then processed in LR6 with some final tidying-up in PSE14.

Shot on 12/09/18 at around 4pm.
