PJ, 'tis wonderful to be able to justify a feathered room.  : )     

Yvonne, here is one I did today using the same method.  I tried a peacock feather but it was too dusty and worn.   These are gelcaps.

The camera is Flatbed Scanner.** Different backgrounds can be used.  The drawback is limited output size but depth of field is surprising.  I did a refrigerator magnet which is about 1 inch deep and it was in focus.

I would love to do a dandelion fluff placed under a gray box or similar, just to see the results.
