I found this leaf while in the park at the weekend. Tonight I soaked it in water so that I could press it flat (well almost, hence there is some depth of field at F2.8). I then put a lamp on the floor and rested the leaf on the lamp shade so that the light bulb acted as a back light, then set up the camera on a tripod above it.
Autumn is well and truly here, sigh, the long slog of winter is ahead.
