you will not get away with this
What do you mean Ivo?
Norman, it is difficult to see any detail in your photos, does your camera have a 'close up' function or macro, sometimes shown on the camera as a small flower? If it does take some more photos with differing and darker backgrounds (this sometimes helps to pick out the engraved detail). If the camera shakes when you take a photo (mine does when I press the button) try resting the camera on a small cardboard box or similar so that the camera does not move.
I have all sorts of boxes for different heights, simpler and quicker for me than using a tripod.
