Thanks for all comments.  I had NO artificial light on the subject pen.  I took the picture on my dinning room table, in a light box, no lights attached. Homemade light box, top and left and right side cut out and white cloth covered.  I have a window on the right side of the lightbox, no window on the left side (only kitchen) and a window behind me.  Camera on a table tripod, pointing down toward the pen about 8" from pen.  I took three pictures plus2, 0, minus 2, as I was going to try it out on PhotoMax.  Maybe had I shaded the pen a little darker or the background a little darker you could not see thru' it.  Maybe using a different larger tube and turn closer would help.  Thanks again for the comments as I really appreciate them.
