The 3 images below were taken using a home-made light box. The idea was to use ambient light evenly distributed and, if needed, a screen to diffuse the built-in flash. Does it work? I think the diffuser needs work.
The beetle is a little bit on the nose. Great subject - formaldehyde?
Looks nice and soft. Not sure if you did anything different between the 3 shots, but the first 2 seem to have lit the front a little better. Very hard to control light on dark, shiny shells like this. Well done in that regard.
Thanks H and Troy. I'll persist with the box and make some modifications. There is a tinge of flash to the first two images. The last is filtered sunlight. Looks like I need some flats as well.
