Yes it seems to be quite round. Both are taken with E-P1, FL-36R, OM Zuiko 50mm 1.4 (aperture set to 4 or 8), one small tripod and 3 sheets of white paper. The first one is in colours and the second is b&w. Iso 100, exposure 3,2 seconds and flashed manually with the test button. Flash is on the right side 90 degrees and the white sheets are on the left side also 90 degrees. The room was very dim. Photos are cropped, sharpness and contrast applied with PSE. Shot as SHQ jpeg.
