Yesterday noticed my Peonies were starting to bloom, so I grabbed my el-cheapo Canon 100mm (non-IS) macro. I was shooting for an artsy look. These were all natural light shots, taken at the worst time of day, around noon. I did use a diffuser, (5-1 reflector kit) to soften the harsh sunlight. In one of the shots I used m poor-man reflector(aluminum foil on cardboard) to kick some light into the center.
