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.
