Today I got home from work too late, so I brought some flowers inside and dug out my light box. The flowers are columbine, lilac, and lily of the valley, with my new macro lens. I think they all were at f/8 with whatever shutter speed worked.
I might have overdone it with the levels adjustments on this one
I went to buy a lens, and they had a new one for cheaper. It's a Canon 100mm f/2.8 (a macro lens). The one I got is an older version, but seems to work fine.
