Nice work,,, To take good pics of the flake scars you need good lighting and macro on the camera for close up shots,,, Try using a lamp with a 60 watt bulb for your lighting source if your taking inside.........You can also take an arrow shaft and stick it i the ground and lay your point on top of the shaft and get some awesome photos, looks like the point is floating in air.
Good Chippin
