Hola Ralph,
Great advise so far from all the other OLD guys here ;), but I have some more for ya. I do a bit of art work for a living and I can pass you a technique to go along wit all these magnification suggestions (which is good by the way).
First: support your elbow a solid flat surface, and thats doent mean your knee (youll get the shakes that way). Do not lock up your wrist or elbow, youre not a robot so dont move like one.
Second: Direct lighting to your subject, nothing matters no matter what if you can't see what youre aiming at.
Third: Magnification... already gone over above.
Lastly: Don't go slow, but not to fast either. Practice on scrap to you find your speed. To slow, shaky To fast, Wild and the lines dont start and stop together
Hope this helps ya out
Jeff
