My feeling is that the focus is so critical with the MPE 65mil (I have one) that you have to be absolutely spot on to get a result. I wouldn't have though the thickness of flesh on a child's arm is translucent enough to permit a necessary amount of light for a decent exposure. However, if you focussed on the entry point, you should be able to photograph that i would have thought - though maybe more like 4X or so? You can borrow my ring light if you like ;-) -- Cheers, Cotty ___/\__ || (O) | People, Places, Pastiche ||=====| http://www.cottysnaps.com _____________________________ * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
